Unglued Ebooks

Ungluing and Copyright

Why does an unglued book have to be in copyright?
Because books out of copyright are already free for you to copy, remix, and share! If a book is in the public domain, it doesn't need to be unglued.
How can I tell if a book is in copyright or not?
Unfortunately, it can be complicated -- which is why wants to simplify things, by making unglued ebooks unambiguously legal to use in certain ways. The laws governing copyright and the public domain vary by country, so a book can be copyrighted in one place and not in another. In the United States, the Library Copyright Slider gives a quick estimate. signs agreements assuring the copyright status of every work we unglue, so you can be confident when reading and sharing an unglued ebook. lists a book that I know is already Creative Commons licensed or available in the public domain. How can I get the link included?
If you are logged in to, the "Rights" page for every work lists the edition we know about. There a link for every edition that you can use to tell us about Creative Commons or public domain downloads. We do require that these books be hosted at certain known, reputable repositories: Internet Archive, Wikisources, Hathi Trust, Project Gutenberg, or Google Books.
