How to cite the Publish or Perish software

If you are using the Publish or Perish software in one of your research articles or otherwise want to refer to it, delight utilize the following format:

Harzing, A.W. (2007) Publish or Perish, available from https://harzing.com/resource/publish-or-perish

Why use Publish or Perish rather than online portals?

Hither's the response of ane of our users; nosotros couldn't have said information technology better ourselves:

Searching for publications through internet portals is a pain as they are typically quite slow, all take different interfaces that aren't peculiarly intuitive and don't help at all to go along track of the searches you have already washed. PoP solves all the issues higher up, it is both easier and faster to use than web portal alternatives. With Pop I experience much more confident that I can perform a systematic review of bachelor literature on a topic when using PoP. I also really like how the results from a search are displayed; it is easy to rank them and/or filter them past a broad diversity of criteria and this is really helpful.

Writer disambiguation (getting simply the author you lot want)

This is a very tricky problem. Even commercial databases like Thomson Reuters Web of Science (ISI) have problems with this, see:

Harzing, A.Due west. (2016) Health alert: Might contain multiple personalities. The problem of homonyms in Thomson Reuters Essential Science Indicators, Scientometrics, vol. 105, no. 3, pp. 2259-2270. Available online...

Nonetheless, there is a lot you can practise to go the correct author by "smart searching". Have a wait at the Publish or Perish tutorial which has lots of tips and tricks. In particular, read the pages on author disambiguation.

Where are "any of the words", "all of the words" and "none of the words" fields in PoP7?

We removed these fields [specific to Google Scholar] to allow for a more flexible and repeatable search across data sources. However, these kind of searches are still possible in the new Title words and Keywords fields by using the Boolean operators OR, AND and NOT [in capitals]. Please note not all data sources allow all operators.

For more information on this see Full general/keyword search in the documentation.

Tin you bring dorsum the discipline categories?

Sorry, information technology is Google who removed them!

Many longstanding users are request to reinstate the subject/subject area categories. Removing them was certainly not past choice: Google Scholar abolished them in 2012; they merits they were not used by most users.

For more information on this come across Google Scholar: missing field of study areas in the documentation.

Why practise y'all requite me these stupid CAPTCHAs?

Nosotros don't issue CAPTCHAs; Google does.

Once more, remember that Publish or Perish is an interface to Google Scholar and other data sources. Nosotros have absolutely no interest in blocking your use of Publish or Perish. On the contrary, we do our best to comply with the various data sources' requirements in terms of query rates and query volumes.

For Google Scholar this may occasionally cause the appearance of a CAPTCHA to verify that y'all are a human, not a robot, if you do regular searches. When that happens, Publish or Perish displays the CAPTCHA to allow yous solve it, then uses the resulting Google Scholar access token to proceed with your search.

In extreme cases Google might return an HTTP condition code 429 (Too Many Requests); in that case you will have to refrain from using Google Scholar for 24 hours or so before retrying.

For more information see Google Scholar: Captchas.

Please notation: Google Scholar Profile searches are non subject to the same captcha requests; the other data sources in Publish or Perish do not display CAPTCHAs either, but may impose their ain limits in other ways.

Why is my h-index in PoP different from ... [Google Scholar,Web of Scientific discipline, Scopus]?

Provided you employ exactly the same search syntax in both, your h-index in PoP and GS will identical (come across Accuracy: PoP vs GS).
The Web of Science (ISI), Scopus, Google Scholar and Microsoft Academic have dissimilar levels of coverage for different disciplines. For a comprehensive comparison, please see: Microsoft Academic: is the Phoenix getting wings?

I'chiliad getting an "Invalid certificate" error when performing a query

This may occur in Publish or Perish version v.ten if you are still using Windows XP. Y'all volition typically see a dialog box like to the following:

Invalid certificate warning

The underlying crusade of the error message is a mismatch between the SSL certificate that Publish or Perish expects for its connection to Google Scholar and the actual certificate provided by Google Scholar'due south server.

It appears that Google sends an SSL certificate for www.google.com instead of scholar.google.com or *.google.com for requests that originate from older versions of Cyberspace Explorer (such as IE8 that Publish or Perish uses on Windows XP, because no subsequently versions than Cyberspace Explorer eight are bachelor for Windows XP).

A more sinister potential cause is that you are using a web proxy (perhaps your organisation's) and that its SSL certificates are invalid or even compromised, or that you lot are using an anti-virus tool or like security program that actively intercepts HTTPS connections and offers its own SSL certificates.

In that location are several (partial) solutions to this issue, depending on the exact crusade. Yous will have to try them each until you detect i that works.

Before you start, brand sure that you are using Publish or Perish 5.27 or later. We accept added some automatic mitigations for the certificate problems in this version of Publish or Perish.

Simply click "Yes" when asked if y'all want to continue. This doesn't solve anything, but it might go you through. It might be necessary to retry your query subsequently clicking Yep for the first time.
--or--
Make sure that yous are Not using a proxy. Proxies are ofttimes badly configured, particularly when you try to perform HTTPS (secure) web connections. Y'all can discover the applicative proxy settings, if any, by choosing Tools > Internet Options from Pop'due south main menu, then going to the Connections tab, clicking on the LAN settings button, and making sure that no proxy is configured.
--or--
Change the Google Scholar URL (if you are trying to perform a Google Scholar lookup, and not Microsoft Academic) to use patently HTTP (insecure) instead of HTTPS (secure): choose Tools > Preferences on the PoP main menu, go to the Google Scholar tab, and edit the Query URL field so it starts with http:// instead of https:// This won't work for Microsoft Bookish --which always uses HTTPS-- and may not work much longer for Google Scholar, because Google is also transitioning to HTTPS-only.
--or--
Upgrade your organization to at least Windows 7 and at least Internet Explorer 11, and make sure that all "recommended" Windows Update updates accept been applied.

Search questions

Why accept Google Scholar queries become so much slower?

To avoid exceeding the maximum acceptable Google Scholar request rate.

In Feb 2013 Google Scholar reduced the maximum number of results per request from 100 to 20. Later on it reduced this further to 10 results per request. This ways that Publish or Perish at present has to perform up to 10 times as many requests per query in lodge to prove the total results.

More data requests mean that Publish or Perish hits the maximum number of requests that Google Scholar allows per 60 minutes sooner.
If the number of requests exceeds the maximum that Google Scholar allows, your IP address volition be temporarily blocked past Google Scholar. This cake tin can last for up to 24 hours.
To avoid hitting the maximum commanded request limit, Publish or Perish now uses an adaptive request charge per unit limiter. This limits the number of requests that are sent to Google Scholar within a given menstruation, both brusque-term (during the last 60 seconds) and medium term (during the last 60 minutes).
To achieve the required reduction in requests, Publish or Perish delays subsequent requests for a variable amount of time (upwards to i minute). The higher the contempo request rate, the longer the delays.

The net result is that queries will take longer than earlier. The culling is being blocked by Google Scholar for upwards to 24 hours. Nosotros consider the relatively short delays during queries every bit the lesser evil, hence the adaptive rate limiter. If you perform queries with few results or but occasionally, so the request charge per unit limiter will have little or no consequence on the query time. In this example, the required delays are curt or non-existent, and Publish or Perish will retrieve effect pages as fast as information technology did in the past.

However, if yous perform queries that yield many results (several hundred or more) or issue a number of queries in short succession, and so the asking charge per unit limiter volition insert progressively longer delays to keep the overall request charge per unit within adequate limits. If you want to avoid this, then the all-time remedy is to spread your queries over the day.

To use the adaptive request rate limiter, make sure that:

You are using Publish or Perish version 4.0.12 or later (if non, and then we strongly recommend that you upgrade to the latest release).
The adaptive rate limiter is enabled and uses the recommended settings.

Publish or Perish merely searches for English language names?

Non so; you can search for any name (or other words) regardless of the language.

Publish or Perish submits your query properly encoded to each data source, so as long as a information source has matching information, the information volition be found. Withal, it tin exist that the data source's coverage of not-English language source textile is less complete than that of English language.

How do I search for names with accents?

If you are looking for an author whose name contains accented letters, then it might help if you include several variations of the name, both with and without accents, and also with the absolute messages missing. The reason for the latter is that some data sources cannot handle absolute letters and either omit them or map them to the closest accent-less equivalent.

For example, to search for someone with the surname Veríssimo (note the accent on the commencement 'i'), utilise the post-obit names in the Authordue south field:

Veríssimo OR Verissimo OR Verssimo

I accept published under several names. How do I detect all my papers?

By using an OR query in the Authors field and specifying all names under which y'all published. For case, if you lot changed you proper name when you married, then use a query that includes both your maiden name and your married name.

How do I exclude cocky-citations from the results?

You cannot practice then directly.

Publish or Perish uses a number of data sources and identifying self-citations requires numerous follow-upwardly queries, potentially exceeding the adequate number of search requests for the data sources. For that reason, Publish or Perish implements starting time-level queries only. If you want to exclude self-citations, you lot must identify them yourself and then exclude them from the Results list by clearing their check boxes.

Can I use Boolean expressions in an author search?

Yes to some extent. The following seem to work with the Authors field:

To perform an "and" search, enter multiple writer names separated past AND [non supported in Crossref]
To perform an "or" search, enter multiple author names separated by OR
To perform a "not" search, enter multiple writer names separated by Not [not supported in Crossref or Microsoft Academic]

Note that if you utilize initials or given names, you lot need to put quotes effectually the proper name, e.yard. "A Harzing". Also notation that the Boolean operators need to exist in UPPERCASE to exist recognized as such.

How do I search for all publications by authors affiliated with <my academy name> in Google Scholar?

You cannot exercise so straight.

Google Scholar does non have a amalgamation field in the same fashion that some other data sources have. Hence a search like the one you describe will not always requite reliable results. Yous can endeavor to search with your university name in the General Search Keywords field (for details see General Search: Institutions), simply this volition match the name anywhere in the documents (non only equally author affiliation) and for some universities is not comprehensive. Currently, nosotros therefore cannot recommend this type of analyses with Google Scholar beyond very full general curiosity driven experiments.

Other information sources let for affiliation searches with varying levels of reliability.

For more than information see Affiliation search in the documentation.

Can I use Publish or Perish to identify the main publications in a certain area?

Yes, upwards to a point. Search for relevant keywords in the Keywords or Title words field (see helpfile for description of these fields). The most cited results are (probably) the principal publications.

Tin I utilise Publish or Perish to place the primary authors in a certain expanse?

Yes, upwards to a betoken. Yous can find the main authors (or at to the lowest degree the most cited ones) in both a subject area and in a specific journal.

In a subject: Search for relevant keywords in either theKeywords or Title words field field (see helpfile for clarification of these fields).

In a specific journal: Search for the relevant journal in the Publication name field. You may want to restrict your search to a sure period by using the Year of publication fields.

The near cited results belong to (probably) the primary authors in the field or journal. You can also sort the results list on the Authors column; this groups papers by the same author together and may tell you at a glance who the about agile authors are in a given area or journal.

Why practise I get so many irrelevant results?

Perchance considering your search is overly broad and you just see a tiny subset of the results.

Example: if you search for all papers published in:

"Strategic management journal" OR "Academy of Management Journal" OR "Journal of Concern Venturing" OR "Entrepreneurship Theory and Practice" OR "Academy of Management Review" OR "Administrative Science Quarterly"

then at that place are hundreds of thousands (for some information sources perhaps even millions) of potential matches. However, all data sources restrict the maximum number of results that they return to a much lower number, typically 200-g. You will therefore only see a miniscule portion of the matches and probably not what you are looking for.

To resolve this, brand you search specific. Only search for one or a few journals (for example) at a fourth dimension, and fifty-fifty then restrict the potential number of results by using year ranges, adding keywords, or adding specific author names.

Alternatively, and in particular if you perform a Google Scholar search, you may get too many results or irrelevant ones because your search contains as well many terms and Google Scholar ignores the surplus (empirically, anything beyond the first 250 or so characters) and returns results based just on the first few search terms. If your search contained additional, more specific terms, and then those will simply exist ignored, causing irrelevant results to be shown.

Other data sources than Google Scholar usually have higher limits on the length of the search terms or produce a more or less meaningful error message if you exceed their limits. All the same, you should still listen our advice and make your search specific because overly broad search terms may crusade internal overflows in some of the other data sources, causing them to render zippo results or another error message fifty-fifty if there ought to be a reasonably modest set of results.

How exercise I get more than results than the 200 or 1000 that Publish or Perish allows?

Publish or Perish does not past itself limit the number of results that you will receive. Any limits are imposed by the original data source:

Crossref: 200
Google Scholar: 1000
Microsoft Academic: 5000
PubMed: 1000 (199 for author and amalgamation searches; 199 or 398 for some title and keyword searches, exact details unknown at present)
Scopus: 200
Web of Science: 200

Remember: Publish or Perish is only an interface to these information sources!

The other thing to consider is this: practise y'all actually need more results? Volition y'all really utilize all 200 or 1000 results, or even more than? Would it not be meliorate to make your search more specific, and then you will only get the results that are really relevant to you lot?

If yous really, positively, admittedly, need more than than the number of results that the data source allows for any given search and y'all cannot make your search more specific, then partition your search past using non-overlapping yr ranges. Publish or Perish makes this easy: when you lot click the New push button, the new search will exist preset to the aforementioned parameters equally the original search, and so all you have to practise is adjust the year range in the new search.

Missing papers or references

Publish or Perish doesn't find whatever of my papers!

Assuming that you really have published scholarly papers, there may be several reasons why Publish or Perish doesn't render whatsoever results for your proper noun.

You spelt your name incorrectly. Right whatever typos and try over again.
Y'all entered your given names in full instead of as initials. This may find some papers, merely many publishers just listing the writer'due south initials and a full name search misses those papers. To exist on the prophylactic side, endeavour using both full names and initials in a single query, like this (the "quotes" are highly recommended): "A Harzing" OR "Anne-Wil Harzing"
Your papers are non bachelor online, neither through your publishers nor through your ain spider web pages. If that is the case, so Google Scholar and Microsoft Bookish do non know about your papers.
Yous published in a language other than English. Google Scholar's and Microsoft Academic'south coverage are improving, merely non-English publications still are underrepresented in the results.

Here are more search tips and an explanation of Google Scholar limitations.

Tin yous please add/right [...]?

Sorry, we practice non maintain a publication database.

Publish or Perish is an interface to the various information sources (Crossref, Google Scholar, Google Scholar Profiles, Microsoft Academic, PubMed, Scopus and Spider web of Science). We practise non sit up at night entering your publications in a "Harzing database" as some users seem to remember :-).

Some information sources collect their information by scraping publishers web sites (for example, Google Scholar and Microsoft Academic exercise so), while others rely on data entry past publishers or authors, or employ another form of curation (for example Crossref, PubMed, Scopus, and Web of Scientific discipline).

Regardless of the method used for information collection, occasional errors volition and exercise occur in the external data sources, so you volition need to contact the private data sources for any problems with your publications or citations.

For more than information, run into the Accuracy folio of the Publish or Perish manual.

My newspaper/book does non announced in Publish or Perish. Can you correct this?

Sorry, no. We practise not personally maintain a database of academic publications.

Publish or Perish uses a variety of data sources to obtain its raw data. The quality and scope of their databases vary; some data sources practise automatic processing, others (like Web of Science or Scopus) perform a mixture of automatic and manual curation. However, none of the information sources are perfect and occasional errors or omissions do occur.

This may exist due to:

Papers that are non (yet) available online. This includes many older papers.
The nature of the publication: some books and other non-periodical publications might not be accessible to the data source, or only not included in its corpus.
Publishing in journals to which the data source in question has no access because of the periodical publishers' policy or publishing agreement.

For more than information limitations of Google Scholar, see the Google Scholar pages in the PoP tutorial.

My periodical does not appear in Publish or Perish. Can you correct this?

Deplorable, no. We do not personally maintain a database of academic journals.

Publish or Perish uses a variety of data sources to obtain its raw data. The quality and telescopic of their databases vary; some data sources do automatic processing, others (like Spider web of Science or Scopus) perform a mixture of automatic and manual curation. Nevertheless, none of the information sources are perfect and occasional errors or omissions do occur.

If a particular journal does not appear in a data source, that could be due to i or more than of the following reasons:

The periodical in question is not accessible to the data source in question because of the journal publishers' policy or publishing understanding. This is likely to apply to automatic information sources such as Google Scholar and Microsoft Academic.
The journal in question is non included in the information source'due south corpus. This is likely to apply to curated information sources such every bit Scopus and Web of Science.

Whatever the exact cause, you will need to contact both the journal'due south publisher and the possessor of the data source (recollect, that is non us!) to become them to sort things out between them.

I am a journal editor. How do I become Publish or Perish to listing my journal?

Nosotros do not personally maintain a database of academic publications.

Publish or Perish uses Google Scholar and Microsoft Academic data to summate its citation metrics. You will therefore need to contact them to include your journal. One time they do, Publish or Perish will utilise the same data.

The number of citations for my paper is also low. Can you right this?

Sorry, no. We do not personally maintain a database of academic publications.

As indicated elsewhere on the this website, Publish or Perish uses Google Scholar and Microsoft Academic information to calculate its citation metrics. Their processing is automatic (dissimilar ISI's or Scopus' that involves manual handling and checking, with the associated cost tag) and hence occasional errors or omissions exercise occur.

This may be due to:

Incorrect or sloppy referencing of your paper by others. Try to detect the referencing works to meet if this is the case.
References in older journals or in journals that are not available online. Google Scholar only uses online information; if your paper or the references to it are not online, they will be omitted.
References in journals to which Google Scholar or Microsoft Academic has no access considering of the journals publishers' policy.

For more information limitations of Google Scholar, run into the Google Scholar pages in the PoP tutorial.

Publish or Perish does not find all my publications, but Google Scholar does. Why?

Publish or Perish uses the Google Scholar Advanced Search options. This is not the same as the standard Google Scholar search box. The search results might differ for one or more of the following reasons:

A Google Scholar general search returns papers in which the search terms that you entered announced anywhere - equally author, title, or even in the contents. In contrast, a Publish or Perish search is more specific and will only return papers that match in the fields that you specified: author names only in the author field, championship words only in the title, etc.
Perhaps Google Scholar did not classify your name correctly as an "author", but somewhere else (for example as function of the title - this is ordinarily due to sloppy references to your commodity). A Google Scholar general search volition even so include the paper, but the more specific search that Publish or Perish uses will not if information technology does not discover your name in the "Author" field.

For more details on this, please see Accurateness of the results.

Why do some results accept truncated (...) fields, such as "International Journal of ...."?

In the early days, Google Scholar provided complete records for authors and the publication source. However, since almost 2012 both fields are regularly truncated, with part of the field replaced by dots […..]. We do not know why Google Scholar decided to introduce truncation. It might be related to the "infinite" available in these fields. Unfortunately it can brand finding the right publication very frustrating, both in the Google Scholar interface and in Publish or Perish. For more details see: Google Scholar: Truncation

Workaround: Use Publish or Perish to generate a list of manufactures (including truncated entries) and save the results as BibTeX, EndNote, or RIS/Reference Manager (Select the Query, Correct-click and click Save to File). Import this file into a new binder in Mendeley, correct click and select 'update details'. This completes about of the truncated entries. Delight annotation that this is express to entries where Mendeley can discover the full entry and is thus more probable to piece of work for traditional publications such as journal articles. [Thank you to Alex Harrison at the European Guild of Endocrinology for this tip]

Duplicate entries

My paper appears equally several different entries in Publish or Perish. Tin can't yous combine these?

Publish or Perish uses Google Scholar and Microsoft Academic data and these data occasionally split what yous know is a single paper into multiple entries. This is usually due to incorrect or sloppy referencing of your paper by others, which causes Google Scholar to believe that the referenced works are different. Every bit of Publish or Perish release 3.0.3780 information technology is possible to merge duplicate results manually in the results list.

My paper is duplicated under unlike languages of the same periodical. Tin't you combine these?

Publish or Perish uses Google Scholar and Microsoft Academic data and these data sources volition typically consider different linguistic communication editions of what you know as the same journal every bit separate journals. For example, English language and French versions of a Canadian journal (or merely of different versions of the journal title) will typically be considered to be different. As of Publish or Perish release 3.0.3780 it is possible to merge duplicate results manually in the results list.

Other search and results issues

How do I amend the accuracy with which Google Scholar lists my papers?

In general, this is rather hard, considering a lot depends on the accuracy with which your papers are referenced by others.

However, if you have divide spider web pages for each of your papers, then Google Scholar advises that you lot can add several meta tags to your pages to assist Google'southward crawler to list your paper. In particular, they recommend using the following tags (replace the content="..." bits with your ain data):

<meta proper name="citation_journal_title" content="Journal Name"> <meta proper name="citation_authors" content="Terminal Name1, Beginning Name1; Last Name2, Get-go Name2"> <meta proper name="citation_title" content="Article Title"> <meta name="citation_date" content="01/01/2007"> <meta proper noun="citation_volume" content="10"> <meta name="citation_issue" content="ane"> <meta proper name="citation_firstpage" content="1"> <meta name="citation_lastpage" content="15"> <meta proper noun="citation_doi" content="x.1074/jbc.M309524200"> <meta name="citation_pdf_url" content="http://world wide web.publishername.org/10/1/1.pdf"> <meta name="citation_abstract_html_url" content="http://world wide web.publishername.org/cgi/content/abstract/10/i/one"> <meta proper name="citation_fulltext_html_url" content="http://www.publishername.org/cgi/content/full/10/1/1"> <meta proper noun="dc.Contributor" content="Final Name1, First Name1"> <meta proper name="dc.Contributor" content="Final Name2, Start Name2"> <meta proper noun="dc.Championship" content="Commodity Title"> <meta name="dc.Date" content="01/01/2007"> <meta proper noun="citation_publisher" content="Publisher Name">

If yous don't know what meta tags are, then this data is not for you.

Tin can Publish or Perish automatically identify authors in the list of results?

No; this is too hard with the current results from Google Scholar. Hither is what the Publish or Perish developer had to say about this when he investigated the outcome in March 2009:

Hi Anne-Wil, I have looked into the weighted author contribution problems that you lot raised, and here are my findings. (a) The actual calculations are simple enough and not a limiting cistron. (b) The trouble lies with reliably identifying and tracking individual authors in a set of results. Let me analyze point (b). In a typical prepare of Publish or Perish search results, the Authors field of each results item contains a semi-formatted list of writer names. It is possible, upward to a signal, to dissever each author list into its split up author names. We already do so for the purpose of the Private h-alphabetize, and as well to provide an overview of papers with 1, 2, 3, etc. authors. For the Private h-index this is sufficient, considering each author receives the same weight (namely, 1/due north if 'n' is the number of authors for that paper). Withal, reliably recognizing and tracking a given author, as would exist required for any scheme that assigns diff weights to authors based on their position in the authors list, is a different matter. The Google Scholar information contains a lot of noise (usually through no error of Google, but simply the result of sloppy or inconsistent referencing by humans) that makes this harder than information technology appears. To give merely one example: an author search for "a harzing" [sic] results at the moment [March 2009] in 158 papers, most of which appear to be (co-)authored by you. Looking at the results, your name appears as: A Harzing AK Harzing AW Harzing AWK Harzing AWIL Harzing ...but in some of the results it doesn't announced at all. Now you lot and I may know that all these variations refer to the same person (y'all), but this cannot be universally assumed: - For an author search, the search phrase "a harzing" might give a inkling, but only if you are prepared to follow English naming conventions of one or more than initials followed by a surname. For other cultural conventions, this might non exist appropriate. - What if the author search phrase used several author names, like: "a harzing" OR "c kulik"? - For non-author searches, you don't even have this starting betoken. - For any searches, you lot might want to extract a list of all author names from the results, but and then the matching procedure across the results prepare is even iffier -- perhaps not for semi-unique names such as Harzing, but certainly for the Smiths and Browns of this world. - And then there are completely garbled results, like this one from the same sample: Authors: AW Harzing, R Wal Title: van der (2008). A Google Scholar h-index for journals... This refers to the commodity you lot co-wrote with "R van der Wal", but no algorithm would exist able to find this person in the Authors field. Therefore, to get this to work, we would take to implement some sort of user interface that allows the user to betoken which authors should be combined. This in itself is not rocket science, but information technology will take more than development work to make information technology usable to the average user than nosotros have available at the moment.

Why does Publish or Perish always count years until the current year, and not the indicated menstruation?

Situation: You have simply done a search (any search) with specific start and end years, for instance from 2000 to 2005. However, the results exercise not prove "half dozen years active" as yous expected, simply "ten years agile" (if the search is done in 2009). What'southward going on?

Answer: The search period (2000 to 2005 in the example) restricts the original publications. It does non restrict the citations.

Regardless of the start and end years in your query, the results will ever bear witness the citations until the nowadays twenty-four hour period, requite or take a few weeks. And because Publish or Perish shows citation statistics, we must count all years from the start yr until the present day.

Before you enquire: No, Publish or Perish does non accept control over this aspect of the results; it'southward Google Scholar that provides these data.

What does the Rank column indicate?

"Rank" is but the club in which the information source returned the results, with college-ranked (i.east., lower-numbered) items returned before lower-ranked (i.e., college-numbered) ones.

Depending on the data source, this usually ways that the higher-ranked ones were a better friction match for the search terms, which is not the same thing as existence more highly cited (in the "Cites" cavalcade). On the other paw, another data sources do return more highly cited results showtime, then for those data sources the "Cites" and "Rank" orders more or less correspond.

Common errors

What does error thirteen (was: 8228) hateful?

This means that the Google Scholar response to your query contained a refusal to accept further requests from your IP address. This is usually acquired by an excessive number of prior queries. Google Scholar will ordinarily lift the block after 24 hours.

In most cases, y'all can prevent this blazon of block by using Publish or Perish's adaptive asking rate limiter. This limiter is enabled by default every bit of Publish or Perish release 4.0.12.

If yous are using an older version of Publish or Perish (before 4.0.12) so nosotros strongly recommend that yous upgrade to the latest release.
If y'all are already using Publish or Perish 4.0.12 or afterward, then make sure that the adaptive rate limiter is enabled and uses the recommended settings.

If you lot are unlucky, it could be that your computer is located backside a web proxy that forwards your queries and those of your colleagues to Google Scholar. In that example, all those queries appear to come from a single system equally far as Google Scholar is concerned, which may cause information technology to block further queries from any of you. Contact your local system administrator if you suspect that this might be the instance.

Tip: Equally of Publish or Perish 4.0.15, you can enable Google CAPTCHA support in Publish or Perish past checking the Answer to verification requests option. When enabled, Publish or Perish will reply to Google's request for human identification and present the CAPTCHA image from Google. You can then type in the words shown in the paradigm and submit them to Google. If you solved the CAPTCHA correctly, and then Google volition allow farther admission from your Publish or Perish session.

What does error 514 (No matching data found) hateful?

This ways that the response to your query contained no entries. Possible causes include:

A query that did not lucifer any papers. Attempt changing the query parameters.

Tip 1: The API of some information sources does not permit the use of the words "and", "or", "non" or other mutual/end words in a keyword or title search. Attempt omitting these words.
Tip 2: If you want to use Boolean operators, you lot will need to use capitals e.g. AND, OR, Non. For farther details on search syntax come across: General/keyword search

Your Internet connexion does not piece of work.

What does error 522 (Invalid data) mean?

This means that the information source's response to your query contained no recognizable data. Possible causes include:

The information source's output format has inverse.
Your Net connexion does non work.

While we try to adapt equally rapidly every bit possible to changes in output formats, there may exist a delay of a few days after a information source introduces a new format.

Furthermore, even after we release a new version of the software, y'all must update your own copy of Publish or Perish to receive the benefit of the new software version. Yous can do so through the Publish or Perish spider web page, or by using the Aid > Bank check for Updates command from the Publish or Perish main menu.

After updating the Publish or Perish software, retry the query using the Search Straight push (instead of Search). This retrieves fresh query information, which might resolve the problem.

If nothing else helps, and so please social club an fault study to Publish or Perish technical support as follows:

Repeat the query that failed.
Choose the Tools > Report Error command from the main card.

This generates an mistake report (a plain text file) called PoPError.txt that you should attach to your email to the Publish and Perish support address. We need the information in the error report for an accurate diagnosis.

What does mistake 1027 (Server error) mean?

Sometimes you lot see an error message like the following*:

*The screen shot is from Publish or Perish 6.x. In Publish or Perish vii.x the same mistake may occur, but with numeric code 1027 instead of 12152.

Google Scholar error 12152

The second role of the error message (We're lamentable but it appears that...) originates with Google Scholar. It is occasionally returned past Google Scholar, and e'er (to our knowledge) at the end of a long search -- like the results 980-thousand of a search.

In that location is nothing that we can exercise nigh this and, despite appearances, there doesn't seem to be anything that Google does about it either, so y'all volition just have to live without the last 20 or then results of that search.

What does mistake 1028 (Invalid client asking) hateful?

If you see an mistake 1028: Invalid client asking then the data source found some sort of syntax fault in the query that Publish or Perish submitted. There is ordinarily some additional information nearly the nature of the error displayed as well; if this doesn't make the problem and its solution obvious, and so please submit an error report.

What does error 1150 mean?

This error code appears when Google Scholar sends a CAPTCHA in response to a request and your system contains an out of date version of Cyberspace Explorer. Solving the CAPTCHA requires a recent version of Net Explorer (IE8 on Windows XP and IE11 on all later Windows versions). The Wine emulation of IE is insufficient for this and will also cause this error message.

Y'all can exercise one of the following:

On a real Windows system, run Windows Update to install the latest version of Internet Explorer (in fact, PoP will offer to kickoff Windows Update for you); or
Use a different data source within PoP (nosotros support six different sources, most of which are free or require a free subscription cardinal); or
Wait 3-four hours earlier resuming your queries; or
Proceed on a full Windows organization if y'all are currently running on Vino. This tin can also be a virtual automobile; we employ VirtualBox on Linux and macOS (both iMacs and MacBooks) with Windows 7 inside.

What does error 1544 (Authentication required) hateful?

This error code appears under the post-obit circumstances:

The current data source requires an API central or login account, but none is available; this applies to Microsoft Bookish, Scopus, and WoS, and will exist indicated in the error details.
Your Internet connection requires authentication, usually because of a proxy server.

In the case of a missing API key or missing login credentials, Publish or Perish volition automatically display a dialog box that allows you to enter the required information or employ for an API cardinal as advisable.

If proxy hallmark is required, and then you should either use your regular web browser to cosign yourself to the proxy, or disable the use of a proxy for Publish or Perish.

On Windows, yous can alter the proxy settings as follows.

Start Publish or Perish
From the Publish or Perish main menu bar, choose View, then choose Cyberspace Options. This should evidence the "Internet Properties" dialog box from Windows.
In the "Internet Backdrop" dialog box, click on the "Connections" tab, then click on the "LAN settings" button. This should open the "Local Area Network (LAN) Settings" dialog box equally shown below.
Brand sure that the "Use a proxy server..." checkbox is clear. If it is already clear, then also brand sure that the "Automatically detect settings" box is articulate every bit well. (In the attached screen shot, this box is checked -- but uncheck it if the trouble persists.)
Click OK to close the "Local Area Network (LAN) Settings" dialog box, and so click OK again to shut the "Internet Properties" dialog box.
Retry the search with Publish or Perish.

Updating Publish or Perish fails with error lawmaking 740

This occurs when you attempt to update the Publish or Perish software on Windows XP and later (including Vista and seven). The full error message is:

Mistake 740 while updating the software. The required operation requires height.

This is caused by an old version of the update software; it is not related to the Publish or Perish software itself. To resolve it, do the post-obit.

Close whatsoever running instances of the Publish or Perish software.
Download the latest version of the software from the Publish or Perish page. This volition result in a file called PoPSetup.exe on your reckoner.
Run the PoPSetup.exe programme that you but downloaded. This will update the Publish or Perish software on your computer to the latest version.

This procedure needs to be performed only once; afterward versions of the Publish or Perish updater no longer cause the error message.

Installation under Vino on Linux fails with "Telephone call to unimplemented function"

This is a problem in Wine.

The DLL (sxs.dll) and part (CreateAssemblyCache, or a related function) in question are not bachelor on all Windows platforms, so our installer very carefully:

Checks for the presence of sxs.dll, and then
Checks for the availability of CreateAssemblyCache, and only so
Calls that function.

What Vino does wrong is to provide the DLL and the function, but and so bomb out when the part is called. What they should do instead is either not provide the function at all, or merely return an error lawmaking when it's called.

Update: This problem was resolved in Wine release 1.1.20 when sxs.CreateAssemblyCache() was modified to render an fault code (E_NOTIMPL) rather than causing a fatal error (fix courtesy of Kai Blin). If you experience this issue, and so update your Wine installation to release 1.1.20 or subsequently; this should resolve the problem. You can so use the normal Windows installer as documented on the Publish or Perish on GNU/Linux folio.

Other software issues

What are all these data files doing in the %APPDATA%\Publish or Perish binder?

Publish or Perish stores your queries and their results in files and folders in your personal data folder on your computer. Some of these are essential, while others are merely useful. The precise location of the Publish or Perish data binder depends on the operating arrangement:

Windows: %APPDATA%\Publish or Perish
macOS: ~/Library/Application Back up/Publish or Perish

Yous may find the following folders and files in the PoP information area:

Cache folder: Contains the raw, buried replies from the various data sources. They can be safely deleted (the Tools > Clear Cache control does that) merely volition incur some cost when before queries are repeated and may cause Google Scholar (for example) to throw more than CAPTCHAs at you.
Results6 folder: Contains the parsed results, one .json file per query. Do not delete these, or you volition lose your query results.
Results3, Results5 folders: If you still have these but are now using PoP half dozen.ten exclusively, then you can delete those folders.
Temp binder: Files in this folder may be safely deleted one time PoP has exited.
Trash folder: Contains backup copies of the previous query tree, plus the results of queries that accept since been deleted, just like the Windows Recycle Bin. The Trash contents are (safely) trimmed past the Tools > Clear Garbage command. You can too delete them manually, simply that will make previously deleted results unrecoverable.

Farther information about Popular's backup authorities tin can be plant under "On-disk backup copies" in the Preferences: General dialog box.

Assist! All my folders and queries have disappeared!

Lamentable to hear about this. Couple of points:

You do not have to salvage or archive your data manually. Publish or Perish automatically saves any changes, usually inside 2 seconds of the completion of your query.
But: the last information saving happens just when Publish or Perish is exited normally. This is when the last bookkeeping information is committed to deejay.
Information technology is therefore highly recommended to exit/quit Publish or Perish usually earlier switching off your computer or putting it to sleep. This includes closing the lid of a laptop figurer.
This also applies to virtual machines; just terminating the virtual machine is the equivalent of yanking out the power cable and tin can atomic number 82 to data loss.

It depends on the operating organisation (macOS or Windows) and version (10.13-10.15, or 7/8/10) how well applications are notified of the impending operating system shutdown/sleep/termination, and if Publish or Perish is in the middle of a background save, this may cause issues and pb to data loss.

To restore your queries, do this:

Exit/Quit all running instances of Publish or Perish.
Go to the Publish or Perish data folder on your computer.
- Windows: use Windows Explorer to become to C:\Users\<yourname>\AppData\Roaming\Publish or Perish folder (or just type %APPDATA%\Publish or Perish in the Windows Explorer accost bar and press Enter)
- macOS: in Finder, use the Get > Go to Folder... command to get to ~/Library/Awarding Support/Publish or Perish folder (normally subconscious in Finder)
In that folder, there should be a file called Queries6.qml. There may also be files chosen Queries6.cur.qml, Queries6.new.qml, and Queries6.old.qml.
If there are several of these files, then select the largest (by file size) and rename that to Queries6.qml. You may have to rename the existing Queries6.qml --if any-- for that.
If you tin only notice a small (1-5 kB) Queries6.qml file, then get into the Trash subfolder to look for files chosen q6_xxxxxxxx.qml, where the 'xxxxxxxx' portion is some hexadecimal number.
Select the largest file from these and copy it to the Publish or Perish base folder, and so rename it to Queries6.qml (again, yous may have to rename the existing Queries6.qml file).
Finally, restart Publish or Perish. Your queries should exist back.

And please call up to leave/quit Publish or Perish unremarkably before switching off your computer or forcibly putting it to sleep. (If the estimator is going to slumber due to several minutes of idle time, this is usually non a problem because Publish or Perish will have finished whatsoever background saves by and so, but it's however a expert thought to go out Publish or Perish start.)
