From “Free 'Video Book' From MIT Press Challenges Limits of Scholarship” (The Chronicle):
The [Learning From YouTube] book was peer-reviewed and comes with an ISBN number, but beyond that it has little in common with the books we're used to seeing. Users get to it by visiting a Web site that consists of about 250 "texteos," pages that combine text and video. The videos, many of them produced by Ms. Juhasz's students, encourage readers to reflect on YouTube by learning inside it. The closest thing to chapters are "YouTours," which guide viewers through related pages. That format also makes the book a test of staying power: Since much of the content isn't owned by Ms. Juhasz, its owners could take it down, leaving holes in her book.
