I just attended a webinar on the CLIR Hidden Collections grant that would be great for your project. I would recommend going to their site – they solely fund cataloging projects that deal with unprocessed collections like yours. They’ve just opened their application but it is due rather quickly, I believe it’s due March 22. There are also great resources listed on that site. http://www.clir.org/hiddencollections There are many institutions they’ve funded that I am sure would be happy to help you.
