E-books offer several key benefits, both to producers and consumers of texts, including shortened production cycles, distribution channels that permit wider circulation of more timely material,and new ways of representing content on a particular topic. Sound, movies, and simulations facilitate a deeper understanding
of subject matter, while annotation features let users create customized versions of a text. Marked-up versions of texts give students an opportunity to demonstrate comprehension by highlighting patterns or themes they discern in a text, and e-book functionality applied to dissertations similarly provides scholars with a broad range of tools to express meaning. E-books offer new ways for readers to experience and interact with content. An e-book that abandons the notion of reading from front to back, for example, encourages readers to take an active, self-directed role in how they learn, letting them make individual decisions about which path they take through a text.
