Some people like the sound of a good book, and iTunes has plenty to offer in its Audiobooks area. You can find verbal versions of the latest bestsellers. Prices depend on the title, but are usually cheaper than buying a hardback copy—which would be four times the size of your iPod anyway. Click any title's name and then the Buy Book button; the rest of the process works just like buying music.
If audio books are your thing, you can find even more of them—all iTunes- and iPod-friendly—at Audible.com (http://www.audible.com), a Web store devoted to selling all kinds of audio books, recorded periodicals like The New York Times, and radio shows. To purchase Audible's wares, though, you need to go to the site and create an Audible account. The Audible site has all the details, plus a selection of subscription plans to choose from.
If you use Windows, you'll need to download a small piece of software from Audible called Audible Download Manager, which slings your Audible files into iTunes. Mac fans don't need to worry about that, as the Audible files land directly in iTunes when you buy them.
