James S. Heller, The Librarian's Copyright Companion (2012)
“ Letting others use the works your library publishes will increase the social benefits of your publishing efforts. A good way to grant copyright permissions is through open licenses. Think of these like copyright notices, but for granting permission rather than reserving rights. By using an open license, you grant blanket permission to anyone who wishes to use your works, subject to conditions prescribed by you. ”
