Web service which allowed users to save and share citations to academic papers

CiteULike was a web service which allowed users to save and share citations to academic papers. Based on the principle of social bookmarking, the site worked to promote and to develop the sharing of scientific references amongst researchers. In the same way that it is possible to catalog web pages (with Furl and delicious) or photographs (with Flickr), scientists could share citation information using CiteULike. Richard Cameron developed CiteULike In February 2019, CiteULike announced that it would be ceasing operations as of March 30, 2019. When browsing issues of research journals, small scripts stored in bookmarks (bookmarklets) allowed one to import articles from repositories like PubMed, and CiteULike supported many more. Then the system attempted to determine the article metadata (title, authors, journal name, etc.) automatically. Users could organize their libraries with freely chosen tags and this produces a folksonomy of academic interests.

Initially, one added a reference to CiteULike directly from within a web browser, without needing a separate program. For common online databases like PubMed, author names, title, and other details were imported automatically. One could manually add tags for grouping of references. The web site could be used to search public references by all users or only one's own references. References could later be exported via BibTeX or EndNote to be used on local computers.

CiteULike provided bookmarklets to quickly add references from the web pages of the most common sites. These small scripts read the citation information from the web page and imported into the CiteULike database for the currently logged in user. Sites supported for semi automatic import included Amazon. com, arXiv. org, JSTOR, PLoS, PubMed, SpringerLink, and ScienceDirect. The RIS file format was also available for commercial bibliography programs such as EndNote or Reference Manager. It also allowed import into the free Zotero bibliography extension of Firefox. Export was possible for individual entries or the entire library. CiteULike gave access to personal or shared bibliographies directly from the web. It allowed one to see what other people had posted publicly, which tags they had added, and how they had commented and rated a paper. It was also possible to browse the public libraries of people with similar interests to discover interesting papers. Groups allowed individual users to collaborate with other users to build a library of references. The data were backed up daily from the central server.

CiteULike was written in Tcl, with user contributed plugins in Python, Perl, Ruby and Tcl; some additional modules were written in Java; data were stored using PostgreSQL There was no API but plugins could be contributed using Subversion. The software behind the service was closed source, but the dataset collected by the users was in the public domain.

The site stemmed from personal scientific requirements. The initial author found existing bibliography software cumbersome. CiteULike was created in November 2004 and further developed in December 2006, running until March 2019. The site was based in the UK. The service was free and was run independently of any particular publisher with a liberal privacy policy.
