With the proliferation of ways in which consumers can get their hands on books today, it's easy to forget that public libraries offer much of that material completely free of charge; the Libby app, however, makes using the power of the library simple. The app is connected to public libraries, and it makes use of their audio book stores to offer up tons of free content for users.
Just like with the public library, Libby app users will need to connect their library card. However, the app lets users connect to as many libraries as they'd like — they only need a card for the library in question, and then they've got access to every e-book and audio book on file.
Considering that people can use so many different online means to purchase books, the Libby app is a reminder of the utility of the library as a public resource.
