To fetch entries from an online database, choose View → Web search, and the search interface will appear in the side pane. Select the database you want to search (e.g. arXiv) in the dropdown menu. Enter the words of your query, and press Enter or the Search button. The results are displayed in the import inspection dialog.
Some of the databases support advanced search queries. These are described on the detail page of the database.
Apart from fetching entries by using a full search it is also possible to directly create an entry using a unique identifier.
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 to extensiviely you might get blocked (for some time).
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.
If you need to use an HTTP proxy server, you can configure JabRef to use a proxy using the "Network" preferences (Options → Preferences → Network).
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).
The Collection of Computer Science Bibliographies is a public search engine for bibliographies of scientific literature in computer science.
You may use Lucene syntax, available fields are: ti (title), au (author), yr (publications year). In short: the default operator is 'OR', use '+' and '–' operators to specify ('+') required and ('–') forbidden words. Wildcards: '?' – single letter, and '*' – part of the word (at the end of a word), '~' – specified at the end of a word makes approximate match (allows typos, but takes many seconds to process)
It is possible to limit the search by adding a field name to the search, as field:text. The supported fields area:
title: The title of the article
doi: The DOI of the article
issn: The ISSN of the journal
publisher: The publisher of the journal
abstract: The abstract of the article
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.
You can simply enter words / names / years you want to search for, or you can specify search keys. Supported keys are:
all - all words. Not specifYing a search key results in an "all" search
tit - title words
per - authors, editors, etc.
thm - topics
slw - key words
txt - tables of content
num - numbers, e.g. ISBN
kon - names of conferences
ppn - Pica Production Numbers of the GVK
bkl - Basisklassifikation-numbers
erj - year of publication
queries can be combined with "and". The use of "and" is 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?"
"per grodke and tit db2"
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).
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.
IEEEXplore is a scholarly research database that indexes, abstracts, and provides full-text for articles and papers on computer science, electrical engineering and electronics. IEEEXplore comprises over 180 journals, over 1,400 conference proceedings, more than 3,800 technical standards, over 1,800 eBooks and over 400 educational courses (Wikipedia)
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, except omitting the find or fin command. This help page will only give a brief introduction to the search queries. More extensive help on searching INSPIRE-HEP can be found on the page http://inspirehep.net/info/hep/search-tips .
Your query can be composed of several parts, combined using and and or as logical operators. Each part is composed of a letter or word indicating the type of field to search, followed by a space and the text to search for.
The following list shows some of the field indicators that can be used:
a or author: search author names
t or title: search in title
j: journal. 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.
k: search in keywords
a smith and a jones: search for references with authors "smith" and "jones"
a smith or a jones: search for references with either author "smith" or author "jones"
a smith and not t processor: search for author "smith" and omit references with "processor" in the title
MathSciNet is a searchable online bibliographic database. It contains all of the contents of the journal Mathematical Reviews (MR) since 1940 along with an extensive author database, links to other MR entries, citations, full journal entries, and links to original articles. It contains almost 3 million items and over 1.7 million links to original articles (Wikipedia).
MEDLINE is a bibliographic database of life sciences and biomedical information. It includes bibliographic information for articles from academic journals covering medicine, nursing, pharmacy, dentistry, veterinary medicine, and health care. MEDLINE also covers much of the literature in biology and biochemistry, as well as fields such as molecular evolution (Wikipedia).
There are two ways of specifying which entries to download:
Enter one or more MEDLINE IDs (separated by comma/semicolon) in the text field.
Enter a set of names and/or words to search for. You can use the operators and and or and parentheses to refine your search expression. See OVID operators for full description.
