The iPad is not classified as an eReader, but you can download books to this device. The iPad allows you to surf websites, write emails, flick through photos or watch videos. The device has a touch screen and thousands of apps are available.
The Library's Digital Downloads collection is awaiting a native app for the iPad. In the meantime, you can access thousands of ebook titles via apps from Amazon, Borders, and Barnes and Noble. Free ebooks can be found through Project Gutenberg.
