OpenStax Textbooks is an educational nonprofit based at Rice University that provides cost-free access to open educational resources. Openstax is an ideal choice for a first introduction to the world of open textbooks: Its reputation for quality, user-friendly interface, and commitment to student success make it an excellent resource.

OpenStax has created a library of 27 peer-reviewed open textbooks that are updated through a centrally controlled errata process. These texts are used widely by institutions all over the United States, and are geared towards general ed courses. OpenStax also features supplementary materials that can be used in conjunction with these textbooks for assignments and for additional instruction. For students who prefer a physical copy of their textbooks, students can purchase a printed text at low costs, or can print the relevant portion themselves.
