A book title can refer to many editions. Page counts, covers, publication details, and ISBNs may differ between a hardcover, paperback, ebook, or audiobook. Searching by ISBN helps MyBibliotheca find a result for the specific edition you are reading.

Search or scan an ISBN

On Add a book, search by title, author, or ISBN. ISBN-10 and ISBN-13 can both be used. If you are holding a printed copy, choose Scan ISBN and point a supported phone or computer camera at the barcode. Check the result before adding it; you can still type the number if camera access is unavailable.

If search does not find the book, enter it manually with at least a title. You can fill in the author, ISBN, status, rating, and notes when you have them, then update the record later.

Choose a cover for your own copy

If the automatic cover is missing or belongs to a different edition, open the book’s detail page and choose Change this cover. Search with the ISBN for the edition you want, review the available options, then choose the one that matches. You can also upload a JPEG, PNG, or WebP image up to 5 MB. Uploaded covers are processed and private to your library entry; they do not replace the shared catalog cover for other readers or appear on your public profile.

The page count matters for progress too. Set Edition page count to the number of pages in the copy you are reading so a position or percentage is meaningful for that edition.
