Is the Concept of Copyright Changing?

Pat Moser, Sidwell Friends School, asked a group of educators, "What's a librarian to do?" and we could stretch that to add teachers and students as well. The confusion over copyright and Fair Use seems to be growing as more and more content is available digitally. Moser wants to know "if copyright laws are destined for oblivion", "if we should feel free to copy and adapt", how authors will be compensated for their work, and "what DO we tell our students about copyright?" She suggests we check out Joyce Valenza's Fair Use and Transformativeness: It May Shake Your World and Harvard's Opt Out Plan as we think about where we are heading. Renee Hobbs, Temple University says, "Copyright is designed not only to protect the rights of owners, but also to preserve the ability of users to promote creativity and innovation." What does that mean to those in the classroom and what does that mean to those producing writing, film, photographs, and other works that may be copyright protected?
