I recently downloaded a trial for
Endnote, a proprietary reference manager. I wouldn't recommend it, especially for the price as free open-source alternatives like
JabRef do a much better job at no cost. That, and I use
LaTeX with
BibTeX for my papers, and JabRef works much better with that. Another option that is more LaTeX friendly is the
Mendeley beta. It looks better than JabRef, but doesn't have all the functionality and is definitely beta. The built-in pdf viewer isn't to good, either.
However, if you need to get references from BibTeX into Endnote, you can easily use JabRef to do so. First, open your .bib file in JabRef. Then, go to
File->Export
and select
RIS (*.ris)
as the file type. Save the export, then open up Endnote. Go to
File->Import
and choose the saved export. Pick
Reference Manager (RIS)
for the import options and hit
Import
. Viola!
