Open access textbooks are textbooks and related materials that are openly licensed and freely available for anyone to use, reuse, and redistribute. They offer several benefits over traditional textbooks such as being available in digital format at low or no cost to students. Creative Commons licensing allows faculty and students to customize and remix open textbook content to better meet their needs. However, open textbooks still need to demonstrate their quality and ability to meet pedagogical standards. Advocates argue they could help reduce the financial burden on students from high textbook costs if adopted more widely.
