The OpenStax project at Rice University provides high-quality, Open Access textbooks that are freely available on the Internet. The textbooks can be accessed on multiple convenient formats, including view online, PDF, Kindle, and print. The OpenStax web site (<>) serves as the main gateway for the project. Users can access textbooks here, sign up for instructor access, and get support. Currently there are 40 textbooks available aimed at popular undergraduate general education courses. The main web site is generally well organized and functions as expected; however, there are some confusing interactions with the legacy CNX web presence that hosts OpenStax content. One major limitation is the current lack of coverage (more textbooks are under development). Overall, it is a highly recommended resource.
