Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
With iTunes, you get a program that does many things. It serves as a database for all the audio, video, book, and podcast files in your media library. It converts tracks from compact discs into digital files for iPads, iPods, and iPhones. And it even has its own online mall that you can pop into any time of day or night to buy the latest Stephen King audiobook, grab a copy of the new U2 album, or rent a digital download of Julie & Julia for the evening.
