There's some interesting repartee going on in The Library, discussions between Siva Vaidhyanathan and Peter Hirtle of LibraryLaw Blog as to the scope of fair use with respect to nonfiction. Hirtle, applying the traditional fair use factors, explains how a reasonable librarian might conclude copying a whole chapter of a book for school-assigned reading is not fair use. Why not just put a statement in the front of the book giving permission for such uses? The terrible secret, Siva asserts, is that authors typically do not control their works. Publishers do, and publishers don't just apply copyright law but an imaginary, extreme copyright policy. They should be smarter and bolder, given that they are both owner and users of copyrights.
