Did you know that Saylor Academy maintains dozens of open online courses?
In addition to these textbooks, students, schools, and professors are also using Saylor vetted, curated and/or created OER located in our open course library. In some cases, the courses become the textbook replacement. Please review our course catalog where you’ll find commonly taught courses matched up with learning outcomes supported by professor-vetted OER. We encourage educators to mine our courses and put them to work in their own classrooms. Find out more at our Open Course Resource Center.
Most HTML versions of these textbooks are available on our GitHub page, where we invite improvements and contributions back to the repository. We will also periodically review errors submitted here (view current list).
How to search
Use Ctrl + f (Windows) or Cmd + f (Mac) to look for specific terms in the books’ titles. Most mobile browsers also have a “find in page” function. The titles and contents of the books are fully searchable here.
