Textbuch is a creator of digital textbooks for university and high school students. The current model of textbooks is flawed. Current digital textbooks are no more then digital copies of real world textbooks; yet they can be so much more. Professors should be able to edit textbooks on the fly, and add relevant content. Students should be able to read their textbooks on any device they want and should be see all of their content synced wirelessly between them.
