Many websites offer ebooks and audiobooks at no cost. Project Gutenberg lists more than 67,000 out-of-copyright titles which can be read online or downloaded in a wide range of formats. Similarly, Librivox offers more than 16,000 audiobooks of old titles, read and recorded by volunteers all over the world. Your local library may also lend copies of ebooks, comics and audiobooks via your library card and an app, such as OverDrive, Libby or BorrowBox. You can then read your choice on a smartphone, tablet or a compatible e-reader like a Kobo, Nook, PocketBook or Tolino – Kindles are not supported. The books will disappear from your “shelf” in the app on the day they are due back, so you don’t have to worry about late fees.
