The USF Tampa Library has a useful site about copyright at http://www.lib.usf.edu/public/index.cfm?Pg=CopyrightInformation.
Two new websites, created by the University of Texas-Austin’s Harry Ranson Humanities Research Center, could also be useful, especially as they build up.
- Firms Out of Business (FOB) can be searched for the contact information of copyright holders for out-of-business printing and publishing firms, magazines and literary agencies
- Writers, Artists and Their Copyright Holders (WATCH) contains copyright holders information for authors and artists
