There was some discussion of this event a few months ago:
I just wanted to let everyone know that I'm definitely going to be attending and giving a brief presentation on VuFind. There will also be a couple of talks related to the new Brandeis VuFind instance (http://loufind.brandeis.edu/). Will any other VuFinders be in attendance? It might be a good opportunity to meet some of the people from the mailing lists....
