Keep a shopping list and a record of your reading, too. Core features are free, with no ads. ■ Add books by barcode Scan an ISBN barcode to look up the title, author, cover, and other details. Add several books with continuous scanning or a list of ISBNs. No barcode? Use the camera to read a printed ISBN. You can also enter book details yourself when a search finds no match. ■ Know where your books are Create shelves for rooms, storage boxes, or ebook stores.

When you rearrange your shelves or move home, select several books to change their shelf together. ■ Browse covers or narrow your search Choose a cover grid or a detailed list. Search by title or author, and filter by shelf, tag, or reading status. Save a rule such as “unread books” as a Smart List, and matching books appear automatically. ■ Keep a list of books to buy Add books to your cart, track preorders, check the total price, and set release reminders.
