Am doing research into the Mound City (IL) Naval Yard for a paper I'm doing in school. I've searched the local histories, related web-sites, etc. Would anyone else have any ideas on where to look? Like good history of the yard, I know the ships built (from o.r.'s) and have a basic history of the place, looking now for details of the ship yard, possibly what the ship ways looked like, and the such. Looking for photos also.

Thanks, Mike
