When the checkout period for an e-book expires, the book is automatically returned to the Library collection. You may have to manually delete the book from your computer, e-reader, or mobile device.
A free Adobe Digital Editions account is also required. Adobe Digital Editions is a software program that manages your downloads and helps to transfer e-books to many devices. To use Adobe Digital Editions, you'll need a Windows or Mac computer or laptop that meets Adobe's system requirements.
