Open Textbook Library
Verified working Aug 1, 2026
A searchable catalog of free, adaptable textbooks for college courses.
Open Textbook Library is a University of Minnesota–based directory of open textbooks that can be used, downloaded, modified, and redistributed at no cost. The collection covers a wide range of academic subjects and lists more than 1,800 textbooks, with search, subject browsing, new releases, and forthcoming titles from Open Education Network members.
Why it stands out
- Focuses specifically on textbooks rather than mixing them with every type of educational resource.
- Large collection size for a curated open-textbook directory, with 1,866 titles listed on the page.
- Emphasizes reuse and adaptation rights, not just free online reading.
- Backed by the Open Education Network and the University of Minnesota’s Center for Open Education.
Good to know
- Collection scope is limited to open textbooks, so it is not a complete courseware or lesson-materials platform.
- Users should review each textbook’s individual license and available formats before adapting or redistributing it.
- Forthcoming titles listed on the site may not yet be available for teaching use.
Under the radar: Check the “Coming Soon” section when planning future courses; it can reveal in-development textbooks from OEN member institutions before they appear in the main catalog.
