Greetings, Please let me suggest one very helpful book in this area: Permissions, A Survival Guide: Blunt Talk about Art as Intellectual Property by Susan M. Bielstein. 188 pages. University of Chicago Press. Cloth $30.00 ISBN: 9780226046372 Published July 2006 Paper $15.00 ISBN: 9780226046389 Published July 2006 Also, I would echo James Cortada's comments. Keep good records, be nice, and give yourself plenty of time to obtain any needed permissions. I've been the Illustrations Editor for the History of Cartography Project for 11 years now and it took me nearly two years to wrap up permissions for the over 1000 images used in our last volume. Some were easy, some were really painful, some were free, some put a big dent in our budget. It had to be done as our publisher would not print the book until I gave them copies of the signed permission forms/letters from the 250 sources worldwide. Hoping this is useful, cheers, Dana Freiburger, Doctoral Candidate History of Science Dept, UW-Madison
