Copyright textbooks for librarians and educators

I am teaching copyright again this fall and again will be using the Crews textbook, Copyright Law for Librarians and Educators.  However, a recent book catalogue had me wondering what other copyright or intellectual property-related textbooks are on the market and I found these.  Among them are some interesting titles and topics, including censorship and licensing.  I'm providing Amazon.com links for the books, however, they are also available - both new and used - through other booksellers.  Enjoy!
