OS X Mavericks introduced two new apps to the Mac that heretofore had only been available for iOS: Maps was one, and iBooks was the other. iBooks enables you to read electronic books available for download from the App Store. It integrates its own App Store interface so you can buy, download and read samples of books available online. In addition to letting you read and buy ebooks, iBooks does more than that. It's also a terrific study aid for Mac-wielding students, as it enables you to easily make annotations to what you're reading. Drag your cursor across a section of text and you can highlight, add a note, and copy the text. Educators who create coursework can create their own ebooks for iBooks distribution using iBooks Author, a free app available for download from the Mac App Store.
