It is well worth reading through Bruce D'Argus' blog that focuses on bibliographic metadata <http://netapps.muohio.edu/movabletype/darcusb/darcusb/>. Bruce is a social scientist, and has become active in the MODS community. He is also promoting the project to add bibliographic support in OpenOffice <http://bibliographic.openoffice.org/>. If a web application would be an option, Simon Fraser University has a very nifty web option called Citation Manager <http://stalefish.lib.sfu.ca/CitationManager/>. I get the sense that the "cite while you write" and integration with applications like Word are key functions for ProCite users, and this often gets into COM bridges and other messy platform-specific plumbing. I went through some options for creating a toolbar at one time and this was one of the major dilemmas, I did not want to get into platform-specific software but it's often hard to achieve close integration with third-party applications if you don't want to work at this level. The Research Task Pane <http://www.devx.com/codemag/Article/18214> in Office might provide another route into this space. If you can get the hooks into word processing programs, I suspect that a web option is far more preferable for collecting citations on every other front. art
