OpenStax (formerly OpenStax College) is a nonprofit educational technology initiative based at Rice University that produces peer-reviewed, openly licensed textbooks for undergraduate education. Founded in 2012, OpenStax publishes digital textbooks and low-cost print editions under Creative Commons licenses, with the goal of reducing the cost of higher education. Their materials are used internationally across a wide range of disciplines including science, mathematics, social sciences, and business. OpenStax has created peer-reviewed, openly licensed textbooks, which are available as free downloadable PDFs, web versions, audiobooks and for a low cost in print. Most books are also available in Kindle versions on Amazon.com and in the iBooks Store. OpenStax's first textbook was College Physics, which was published online, in print, and in iBooks in 2012. OpenStax launched OpenStax Tutor Beta in June 2017, adaptive courseware based on cognitive science principles, machine learning, and OpenStax content. However, it was announced in October 2022 that Tutor was being discontinued. More information...
