Open textbooks are digital educational textbooks made freely and legally available for anyone to reuse, revise, remix and redistribute to meet their course needs.

Studies investigating student success – as determined by factors such as course completion, course grades, GPA, or withdrawal rates – have demonstrated that students in courses utilizing open textbooks did as well or better than students in similar courses utilizing traditional, commercial textbooks (Clinton & Khan, 2019; Fischer, et al., 2015; Griffiths, et al., 2022).
