ps - if anyone has found a good solution for sharing a single EndNote file (so that multiple people on a research team can update a single database over a network), can you please let me know how you do it?

I've observed that this (serious collaboration among numerous people) is generally the point at which it begins to make sense to switch from endnote to bibtex for reference storage. Several of the lab groups I've interacted with use BibTeX as the central point of storage for bibliographies, with updates managed via either CVS or SVN checkins. This seems to work well; individual users can still import the revised version of the bib into endnote for their desktop use if they like. Part of the reason for this is that .enl files are binary, and that version control of binary files doesn't often make much sense. (And when it does, people call it "asset management" instead... :) ) <tangent> People seem to find that good version control of their documents is a miracle, of sorts -- once you've experienced it, generally when it saves you from a disaster of some kind, you never want to give it up. Ever :-) Version control, from a sociotechnical perspective, is a *very* interesting set of moves. </tangent> --elijah
