Apple's tablet comes with the company's iBooks app installed by default. The app works seamlessly with the company's iBooks Store, but the iPad also supports many other types of digital book formats. You only need to download the appropriate app. There are dozens of e-book formats that you can access on your iPad, but these are the most common ones: Apple Books The books purchased through the Books Store are in the ePub format, but they are modified to include Digital Rights Management to prevent unauthorized sharing or copying. Any ePub digital book can be opened in the Books app or in other downloadable apps. ePub The ePub open format is one of the most commonly used e-book file types. Apps like iBooks and Nook can read ePub files purchased from their respective online stores or downloaded from the web. Several programs for Mac and Windows convert other kinds of e-books to ePub format. Barnes & Noble Nook Barnes & Noble sells e-books on its website and through its Nook app. Access these books using the free Nook app available at the iPad App Store. Nook e-books are a renamed version of the common ePub file type. Kindle Amazon's Kindle isn't just an e-reader that competes with the iPad, it's also an app for the iPad. Read Kindle books on the iPad using the Amazon Kindle app. Kindle e-books are a modified version of the Mobipocket file format and use the .AZW file extension. PDF PDF is probably the most popular downloadable document format on the web, so you're sure to find e-books in this format in a lot of places. There are tons of PDF-compatible apps for the iPad, including Adobe Acrobat Reader, GoodReader, and iBooks. CBR and CBZ CBR and CBZ formats are related types of digital book formats that are used to present comic books and graphic novels. To read them on the iPad, you need an app such as the free Manga Storm CBR app or the paid app Comic Zeal. comiXology Amazon's comiXology is the leading online comics and graphic novel store. You buy comics on the website and then use the comiXology app on your iPad to download and read your purchased comics, which come in file types that include PDF, CBZ, and the company's proprietary CMX-HD format. KF8 Kindle Format 8 is the next-generation version of the Kindle e-book file. It adds support for HTML and CSS to the existing Kindle format and uses the .AZW3 extension. The Kindle app on the iPad supports the KF8 format. Microsoft Word Microsoft Word creates .docx files. Some e-books, usually those sold as direct downloads by self-publishers, come in this format. While there are a number of iPad apps that can read DOCX files, Microsoft Word for iPad is free. Mobi Amazon's use of a modified version of Mobi for the Kindle makes this file format one of the most widely used for e-books. Outside of the Kindle, though, you likely won't encounter it too often. The best way to read Mobi files on your iPad, which does not support the Mobi format, is to use a program like Calibre E-Book Management Software to convert the Mobi files to ePub format. Then read them in iBooks or another ePub-compatible reader app. Plain Text Plain text files, which have the .TXT file extension, pop up from time to time, especially on sites that offer free, public domain books, such as Project Gutenberg. A large number of apps support plain text files, including the paid app GoodReader, and iBooks. iPad Audiobooks Support The iPad can also be of use if you prefer to get your books in audio form rather than text. Some of the most common audiobook types supported by the iPad include: Audible: Audible.com uses its proprietary formats (.AAaa, .AAX, and .AAX+) and is probably the most popular and widely used audiobook service on the internet. With the free Audible.com app for the iPad, enjoy any book from that site on your tablet.MP3: Other audiobooks are often delivered as standard MP3 audio files. Because that's the same format as many music files, download an MP3 and then sync it to your iPad to listen to it using the built-in Music app.
