Open-Source Textbooks

This page contains some links to similar open-source textbooks. Notice however that a book that is free to download, but with a copyright that reserves the author's rights, is not really free. For a book to have freedom, the copyright holder needs to grant the text additional freedoms through a license that makes these conditions explicit. For this reason, I have included some links to different licenses and essays on open-source.
