from pybliographer-general, several bugfixes and better BibTeX handling are now available. Go get it here.
from freshmeat: "Corrected problems when opening an empty bibtex file. pybconvert script fixed. Updated German and Italian translations." see pybliographer.sourceforge.net (new url) for more.
from freshmeat: "bibmaster is a user interface to BibTeX databases. It is text-based and does not require a graphical interface. Features include direct use of the BibTeX format, the ability to add and edit entries, online help, search in any database field (using regexes), keyword editor enabling deletion and replacement of keywords in the database, produce a postscript file of selected entries, and the ability to read and write RIS files (used by ReferenceManager)." Read more here.
bp is a freely licensed perl package for manipulating and accessing bibliographic information. It supports bibtex, refer, endnote, procite, inspec, medline and other formats for input/output/conversion. I emailed the author as the bp homepage does not seemed to have changed in two years... will post any response as a comment.
seen at freshmeat and from the site: "pybliographer is a tool for managing bibliographic databases. It currently supports BibTeX files for reading and writing, and can also read Ovid files... It can be used for searching, editing, reformatting, etc. In fact, it's a simple framework that provides easy to use python classes and functions, and therefore can be extended to any usage (generating HTML pages according to bibliographic searches, etc)."
new features listed at Pybliographer site include speedups, French language support, Medline, and LyX support as well, along with documentation. any end note users should try this out and let him know if it works...
as seen at freshmeat, and at SIXPACK site: "SIXPACK is a free BibTeX and Reference Manager designed to edit, convert and manage reference files, search and sort bibliographies, import and export many different bibliography types. Sixpack uses the excelent perl package bp by Dana Jacobson to covert between formats." and it reads/writes bibtex, refer, endnote, tip, procite, rfc1807, and plain text along with one-way for several others. written in perl/tk... looks real good.
as seen on gnome-list, what's new includes "multiple documents interface, with copy/paste and drag'n'drop; multiple selections (useful with LyX citation for example); all the supported formats (bibtex, medline, ovid, refer) can now be read and written; better date handling; bug fixes." for more see the pybliographer download page at gnome.org. if you haven't tried this yet give it a shot; i might finally get rid of endnote + msword (and there was much rejoicing). :)
As seen at freshmeat, gnome-list, and noted by Matt W.: "Many annoying bugfixes, a graphical configuration mechanism, and an XML-based style format for bibliographic outputs." Go to www.gnome.org/pybliographer (note new url) for more.
as seen at gnome.org: "This version is only a minor bug-fixes release." Btw I've been using this a bit and I'm getting ready to let go of Endnote for good. Wooh-hooh... :)
