Good! The new beta of JabRef, 2.6b3, now has a properly-working interface to JSTOR. One can search by keyword for JSTOR entries, and JabRef lists the hits and lets you import whatever you want to your bibtex database. JabRef even helpfully marks possible duplicates. Very nice indeed, especially for us humanists.

At the moment, JabRef and Mendeley seem to be moving forward fast. They approach the problem of bibliography management slightly differently, and offer different feature-sets. However, both are emerging as seriously useful tools.
