Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
Once you tap the Store icon, you’re transported into the iBookstore—which looks quite a bit like the iTunes Store and the App Store, but with book titles instead of music, videos, and TV programs. But like those other iStores, browsing and searching works pretty much the same way.
The main storefront features new best sellers, popular titles, and books the iBookstore staff finds interesting. If you’re browsing for books on a specific subject, tap the Categories button (circled) and select from the pop-up menu.
