This case study investigated how 23 students adapted to using a completely online textbook in lieu of a traditional paper text. All were enrolled in a single advanced MSW practice course. A variety of adaptation styles evolved. The students' primary strategy was to revert to making paper copies when permitted to do so instead of reading the assigned materials online. While a few students adapted to the electronic textbook, most generally did not because of interface design, time constraints, and study strategies. Implications for further research on relying completely on electronically-distributed reading materials are discussed. (Contains 1 figure.)
