These ebooks are available through a non-commercial agreement. Publishers are not paid for content available for Worldreader e-reading solutions under the "Donated" licensing model. Donated books, however, are sometimes subject to copy limits or geographic restrictions. Donated books include some e-books which contain content in the public domain.
