About

What this site is, who runs it and how it stays free.

FreeTextbookRadar tracks free, open college textbooks — peer-reviewed OpenStax books and the newest titles in the Open Textbook Library — on one page.

Every textbook links to its official page, where you can read it online or download a PDF.

The list refreshes every hour. The site is free to use and funded by unobtrusive advertising.
