I'm currently in Bloomington for a database workshop. There I met Stacy Kowalczyk, who is working on Indiana University's Digital Library program: http://www.dlib.indiana.edu/
I've already given Stacy a brief summary of Wikisource and where I see potential for collaboration (metadata, translation, proofreading..). I will still be here until Friday, so if you guys can come up with useful questions to ask or suggestions to relay, I can do so.
