LibreTexts
Verified working Aug 3, 2026
Open textbooks and adaptive homework tools for educators.
LibreTexts is a nonprofit platform for finding, adapting, and publishing open educational materials. It hosts subject-based textbook libraries, supports remixing chapters into custom course texts, and connects those materials with interactive elements such as homework questions, notebooks, videos, and visualizations.
Why it stands out
- Combines open textbook hosting, authoring, remixing, and homework in one connected OER ecosystem.
- Large cross-disciplinary collection, including science, math, humanities, social sciences, K-12, workforce, and Spanish-language resources.
- Built around educator customization rather than simple read-only textbook access.
- ADAPT adds openly licensed assessment infrastructure, not just static course readings.
- Nonprofit model aimed at institutional OER adoption and publishing programs.
Good to know
- Not a general online course platform; its main focus is textbooks, homework, and supporting course materials.
- Creating custom books or assessments may require learning LibreTexts-specific publishing and ADAPT workflows.
- Coverage and ready-made assessments vary by subject, so specialized courses may still need original authoring.

College faculty and OER librarians can build lower-cost course materials by remixing open textbook chapters and assessments. Adopt an existing open textbook for a biology, chemistry, math, humanities, or workforce course. Create a custom textbook by combining chapters, instructor-written content, labs, and interactive media. Use ADAPT to assign openly licensed homework questions and adaptive assessments. Support an institutional open publishing or zero-textbook-cost initiative.
Subject libraries covering 17 fields; thousands of open textbooks; remixable textbook chapters and ancillary materials; ADAPT homework and assessment system with a large shared question bank; support for embedded Jupyter notebooks, 3D visualizations, videos, and other interactive learning objects; training, webinars, and institutional collaboration programs.
