If you have general questions about copyright, the University of Michigan Copyright Office has a webpage with many useful resources, including information on Creative Commons, Open Access, and Rights Reversion, among others.
They also host workshops, allow scheduled appointments for in-person consultations, and maintain an online guide for common copyright questions.
If you are an author and want to ensure you maintain certain rights for a publication, consider adding a University of Michigan Author's Addenda to your publisher's agreement.
Copyright is an issue with regard to scanning services. Generally, our scanning department can only scan ~10% of a book (or ~1 chapter) to stay within the limits of copyright.
