Searching externally using Online Services
Using online databases to search for references
JabRef is not intended to be a tool for mass download of citations. The purpose of the Web search is to easily gather a few entries directly from within JabRef. If you use the search functionality too extensively you might get blocked (for some time). To fetch entries from an online database, choose View → Web search, and the search interface will appear in the side panel. Select the database you want to search (e.g., arXiv) in the dropdown menu. Note that it might be necessary to scroll downwards to find certain fetchers. An example for this is provided in the image below. You may opt to download the abstracts along with the cite information for each entry, by checking the Include abstracts checkbox.Then enter the words of your query, and press Enter, or the Search button. The results are displayed in the import inspection dialog. Some online services support advanced search queries. These are described below at the respective fetcher.
Apart from fetching entries by using a full search, it is also possible to directly create an entry using a unique identifier.
Mass downloading of articles
However, it is still possible to import hundreds or even thousands of entries from these databases. The process depends a bit on the specifics of each database, but in general works as follows: Search the database in your browser, export the result in one of the supported file formats and then import the file into JabRef.
Using a Proxy Server
If you need to use an HTTP proxy server, you can configure JabRef to use a proxy using the "Network" preferences (File → Preferences → Network).
Search Syntax
Since version 5.2:
JabRef searches the databases by using the specified keywords. One can use quotes (") to keep words togehter: An example is "process mining". It is also possible to restrict the search to dedicated fields:
Thereby, JabRef supports following fields:
| field | meaning |
|---|---|
| The author of the work |
| The title of the work |
| The title of the journal of the work |
| The year in which the work was published |
| The year range (e.g., |
| The document object identifier of the work |
One can usually combine different searches using the Boolean operators AND and OR. Thereby, the default operator is OR.
Examples
author:smith and author:jones: search for references with authors "smith" and "jones"author:smith or author:jones: search for references with either author "smith" or author "jones"author:smith and not title:processor: search for author "smith" and omit references with "processor" in the title
Technial note: The search syntax is adapted from Apache Lucene. JabRef takes the Lucene syntax and transforms it to the syntax required by the supported databases.
Supported databases
ACM Portal
The ACM Portal includes two databases (Wikipedia):
the ACM Digital Library is a text collection of every article published by the Association for Computing Machinery, including over 60 years of archives from articles, magazines and conference proceedings.
the Guide to Computing Literature that is a bibliographic collection from major publishers in computing with over one million entries.

ArXiv is a repository of scientific preprints in the fields of mathematics, physics, astronomy, computer science, quantitative biology, statistics, and quantitative finance (Wikipedia).
Bibliotheksverbund Bayern (BVB)
The Bibliotheksverbund Bayern (BVB) provides bibliographic information from all public libraries in Bavaria, Germany. The format used is MarcXML, which has been modified, which in turn is based on other modifications.
Biodiversity Heritage Library
Biodiversity Heritage Library makes biodiversity literature openly available to the world as part of a global biodiversity community. It is the world’s largest open access digital library for biodiversity literature and archives (Wikipedia).
CiteSeerX
CiteSeerX is a public search engine for scientific and academic papers primarily with a focus on computer and information science. However, CiteSeerX has been expanding into other scholarly domains such as economics, physics, and others (Wikipedia).
Collection of Computer Science Bibliographies (CCSB)
The Collection of Computer Science Bibliographies is a public search engine for bibliographies of scientific literature in computer science.
Crossref / Unpaywalll
Unpaywall is an open database with over 20 million free scholarly articles harvested from over 50,000 journals and open-access repositories around the globe. Sources for these articles include repositories run by renowned universities, governments, and scholarly societies. Unpaywall is integrated into thousands of existing search engines, library platforms, and information products, making articles easy to find, track, and use for your scholarly communication needs.
The Unpaywall database has a very simple structure: it has one record for each article with a Crossref DOI. It harvests from many sources to find Open Access content, and then matches this content to these DOIs using content fingerprints. So for any given DOI, we know about any OA versions that exist anywhere.
To fetch entries from Unpaywall indirectly through Crossref, choose Search → Web search, and the search interface will appear in the side pane. Select Crossref in the dropdown menu. To start a search, enter the words of your query, and press Enter or the Fetch button.
DBLP
DBLP is a computer science bibliography website listing more than 3.1 million journal articles, conference papers, and other publications on computer science (Wikipedia).
DOAB
DOAB (Directory of Open Access Books) is is a community-driven discovery service that indexes and provides access to scholarly, peer-reviewed open access books and helps users to find trusted open access book publishers.
DOAJ
DOAJ (Directory of Open Access Journals) is a database covering more than 10000 open access journals covering all areas of science, technology, medicine, social science, and humanities (Wikipedia).
It is possible to limit the search by adding a field name to the search, as field:text. The supported fields are:
| key | description |
|---|---|
| The title of the article |
| The DOI of the article |
| The ISSN of the journal |
| The publisher of the journal |

Google Scholar
Currently not working, because Google changed their API
Google Scholar is a freely accessible database that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Google Scholar index includes most peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents (Wikipedia).
Traffic limitations
Google scholar can block "automated" crawls which generate too much traffic in a short time. To unblock your IP, doing a Google scholar search in your browser might help. You will be asked to show that you are not a robot (a CAPTCHA challenge). If no CAPTCHA appears, or JabRef is still blocked after performing a search in the browser, you can also change your IP address manually or wait for some hours to get unblocked again.
Thus, the Google Scholar fetcher is not the best way to obtain lots of entries at the same time. The JabRef browser extension might be an alternative to download the bibliographic data directly from the browser.
GVK
GVK, the GBV Union Catalogue, is a multimaterial bibliographic database of seven German federal states. It covers 41.5 million records of books, conference proceedings, periodicals, dissertations, microfilms and electronic resources.
Advanced search
You can simply enter words / names / years you want to search for, or you can specify search fields.
Supported fields are:
| field | description |

| title words (converted to GVK's |
| Searches author, editors, etc. (converted to GVK's |
| The journal (converted to GVK's |
| The year of publication (converted to GVK's |
| topics |
| key words |
| tables of content |
| numbers, e.g. ISBN |
| names of conferences |
| Pica Production Numbers of the GVK |
| Basisklassifikation-numbers |
Year ranges are not supported. In case a year range is provided, it is ignored. Otherwise, GVK returns no results.
Notes
queries can be combined with
and. The use ofandis optional, though.in many cases you can use the truncation sign
?spaces in person names are not supported yet. Please use the truncation sign
?after the first name for several given names. E.g.per Maas,jan?
Sample queries
marx kapitalauthor:grodke and title:db2author:"Maas,jan?"

INSPIRE
INSPIRE-HEP is an open access digital library for the field of high energy physics (Wikipedia).
Query syntax
The INSPIRE-HEP search function merely passes your search queries onto the INSPIRE-HEP web search, so you should build your queries in the same way. INSPIRE supports the fielded search too. See https://inspirehep.net/help/knowledge-base/inspire-paper-search/ for advanced help.
The following list shows some of the field indicators that can be used:
| field | description |
|---|---|
| search author names |
| search in title |
| Here either the common abbreviation or the 5 letter CODEN abbreviation for a journal can be used. Volume and page can also be included, separated by commas. For instance, j Phys. Rev.,D54,1 looks in the journal Phys. Rev., volume D54, page 1. |

zbMATH Open
zbMATH Open is an abstracting and reviewing service in pure and applied mathematics. Its database contains about 4 million bibliographic entries with reviews or abstracts currently drawn from about 3,000 journals and book series, and 180,000 books. The coverage starts in the 18th century and is complete from 1868 to the present by the integration of the "Jahrbuch über die Fortschritte der Mathematik" database (about).
Structured Search
You cannot use the same query syntax as in the one-line search at zbmath.org; you have to stick with the Apache Lucence syntax. This means that your query can be composed of several terms, combined by the logical operators AND and OR. Queries are case-insensitive. Further operators that can be used are NOT for logical negation, * for a right wildcard, " " for exact phrase matches, and parentheses ( ) to group terms. Optionally, it is possible to add a field name in the form field:text to limit the search results. The supported fields are:
| field | description |
|---|---|
| Author, editor - sent in the |
| Author, editor - sent in the |
| Journal - sent in the |
| Year - sent in the |
| Year range - sent in the |
| MSC code |
| document type (possible values are |
| the zbl id of the document |
| internal author identifier |
| language either as a string or as ISO 639-1 language code |
| search for term in reviews or abstracts |
| reviewer |
| software |
| external identifier |
| biographical reference |
