RefDB is a reference and note database. Use it to manage your collection of offprints of scientific publications, or basically any other collection of printed or electronic documents along with your personal notes.

RefDB is also a bibliography tool for markup languages. The bibliography tool allows to create printable or online documents with formatted citations and bibliographies from DocBook SGML/XML, TEI XML, and LaTeX sources.

RefDB can also serve as a data source for other applications. You can either use the SRU interface, or use the Perl and PHP libraries to integrate RefDB functionality directly into your own projects.
