E-books are becoming ever more popular in education. They are cheaper for students and better for the environment than print books, saving about 9.8 million trees per year (Wahl, 2018). They satisfy ADA requirements as the text can be enlarged and read by a print reader. They allow for various types of media, such as audio and video, and can include interactions, such as questions, to reinforce understanding. They are more portable than a backpack full of books and can be downloaded from anywhere. Instructors can modify open-source versions as well as cut them up to use only certain parts in class. Above all, because e-books do not require a professional publisher, anyone can create them.
