The most appealing aspect of this solution for publishers would be the cost efficiency of it. Most publishers say that the excessive cost of textbooks is caused by the extra frills in them (cite). These frills are the supplementary items like CDs, workbooks, and other materials used to help students practice (cite). With a switch to online textbooks publishers could still have those materials with textbooks but instead of them printing them out separately they can just bundle them together. One publisher that I’ve seen does this is McGraw-Hill, for their online textbooks students can read and get questions after every section or chapter to see what they learned. This type of bundle helps publishers can push out extra practice material if needed
