The Libby app allows users to access library books from home, requiring a valid library card for setup. It has evolved from its original version, Overdrive, and integrates well with Android devices. Users can borrow books easily through the app, which is available on the Google Play Store. E-readers like Onyx Boox and Bigme are recommended for use with Libby, particularly the Boox Palma. Transferring library data from an old e-reader to a new one is simple with the Libby app. The app offers various categories for browsing books, a waitlist feature for checked-out titles, and a search function for specific authors or titles. Recent updates include an AI assistant for discovering new books. Libby is ad-free and prioritizes user privacy, making it a valuable resource for readers, especially during the holiday season.
