By default, all digital books under 20 mb (basically e-books only) will download to Libby automatically for offline reading. Unless you tell it otherwise (see the Kindle FAQ below), Libby downloads digital books in the Read or Listen formats. What format are the digital books in Libby? If you want the kids in your life to be able to browse only for kids’ books, and not see other titles, you’ll want to stay with the OverDrive app as well. If you’re concerned about excluding mature content in your digital reading app, stick with the OverDrive app. Also, if you make use of accessibility features in the OverDrive app, you’ll need to stick with that until more accessibility features get added to Libby.

If you like to read books on many devices, or prefer to browse for new titles on your computer, stick with the OverDrive app for now. If you use one iOS or Android device to browse, download, and read or listen to digital books, we recommend trying Libby. Libby is new, and doesn’t yet have all of the features that the OverDrive app does, such as the ability to recommend titles for purchase or robust accessibility features. It also allows for transfer to MP3 players from computers. OverDrive is the “classic” app, and is compatible with more devices, including Kindle Fire, Macs, PCs, and Windows mobile devices. Libby is great if you just want to download a book to your Android or iOS phone or tablet. Libby is compatible with Android and iOS devices, and OverDrive is working on and app for Kindle Fire/HD devices. Libby is a fast and attractive digital browsing experience. It has the same collection of titles as the OverDrive app - it’s just a different way to access the same digital library collection.

Libby is a new app released by OverDrive.
