James S. Heller, The Librarian's Copyright Companion (2012)
“ Fair use ensures that copyright owners do not have a monopoly over transformative uses of their works. The converse is also true. When a use merely supplants a copyright owner’s core market rather than having a transformative purpose, it is unlikely to be fair. Thus, for example, a library clearly cannot acquire current books for its collection simply by photocopying or scanning published editions. ”
