BibDesk
BibDesk is an open-source reference management software package for Mac OS X, used to manage bibliographies and references when writing essays and articles. It is primarily a BibTeX front-end for use with LaTeX, but also offers external database connectivity for importing, a variety of means for exporting, and capacity for linking to local documents.
First launched publicly in 2002, BibDesk is under continuing development by various contributors via Sourceforge. The original developer was Michael McCracken, and much of the code has subsequently been written by Adam Maxwell and Christiaan Hofman. Also available directly from SourceForge, it is currently bundled with the MacTeX distribution of TeX.
Features
BibDesk offers a front-end for creating, editing, managing, and searching BibTeX databases. With integrated connectivity to external databases including PubMed, the U.S. Library of Congress, Web of Science, (and any other databases searchable via the Z39.50 or Entrez protocols), BibDesk enables one-click importing of references to articles and books listed in these databases and library catalogs. It also eases importing unformatted references from websites or documents without requiring that they be re-typed.
