Since 2012, Saylor Academy has shared a selection of openly-licensed textbooks on this page. Beginning in mid-2024, we will no longer host copies of these books. Saylor Academy’s mission to open education to all continues through our catalog of free online courses at https://learn.saylor.org.

If you have a question about a textbook previously hosted by Saylor Academy, please refer to our help center or contact us.
