Online textbooks a less costly alternative at many colleges

As textbook prices skyrocket, college students and faculty seeking more affordable options increasingly are turning to "open textbooks" as an alternative. Open textbooks are free textbooks available online that are licensed to allow users to download, customize and print any part of the text. Professors can change content to fit their teaching styles. Some authors offer a print-on-demand service that produces professionally bound copies for $10 to $20.
