CiteULike is a free online service to organize academic publications, now run by Oversity. It has been on the Web since October 2004 when its originator was attached to the University of Manchester, and was the first Web-based social bookmarking tool designed specifically for the needs of scientists and scholars.

In the style of other popular social bookmarking sites such as it allows users to bookmark and “tag” URIs with personal metadata using a Web browser; these bookmarks can then be shared using simple links such as those shown below. The number of articles bookmarked in CiteULike is more than 3 million (as shown on CiteULike’s homepage). While the CiteULike software is not open source, part of the dataset it collects is currently in the public domain Publication.

CiteULike normalizes bookmarks before adding them to its database, which means it calculates whether each URI bookmarked identifies an identical publication added by another user, with an equivalent URI. URIs have the following format: This is important for social tagging applications, because part of their value is the ability to see who and how many people have bookmarked a given publication. CiteULike also captures another important bibliometric, namely how many users have potentially read a publication, not just cited it. It seems likely that the number of readers considerably exceeds the number of citers [84,150], and this can be valuable information. Time lags matter, too. This is particularly the case with Open Access, where the ‘‘most-accessed’’ Journal of Biology paper of 2007 had in June 2008 been accessed in excess of 12,000 times, but has been cited just nine times (note that early access statistics can provide good predictors for later citations[citation needed]). CiteULike provides metadata for all publications in RIS (EndNote) and BibTeX, providing a solution to the ‘‘Get Metadata’’ problem described in the previous section Metadata: You can’t Always GET What You Want, because every CiteULike URI for a publication has metadata associated with it in exactly the same way.

CiteULike is based on the principle of social bookmarking and is aimed 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 or photographs (with Flickr), scientists can share information on academic papers with specific tools developed for that purpose.

When browsing issues of research journals, small scripts stored in bookmarks (bookmarklets) allow to import articles from repositories like PubMed. Then, the system attempts to determine the article metadata (title, authors, journal name, etc.) automatically. Users can organize their libraries with freely chosen tags which produces a folksonomy of academic interests.
