JabRef is a graphical application for managing bibliographical databases. JabRef is designed specifically for BibTeX bases, but can import and export many other bibliographic formats. JabRef runs on all platforms and requires Java 1.6 or newer.
Just a short comment on version 2.9.2 I like JabRef and especially it's auto file link functions combined with the auto generation of BibTeX keys. But after I installed v. 2.9.2 the file synchronization doesn't work anymore and BibTeX keys are generated in capital letters which I can not (or maybe after searching a lot still don't know how to) change. Both a big problem if handling my old databases. Thus I'm a bit disappointed about the new version which I uninstalled and changed back to v. 2.6. where everything is working fine. I liked the new feature of finding unlinked files which is missing in 2.6 though.
