Build your personal collection with a clear five-book preview, shared across scans, manual entry, barcodes and imports. Pro unlocks unlimited collection building. The preview no longer resets daily. Existing books remain accessible. Large imports can preview their first new books before you upgrade. Cancelling an upgrade keeps your entry or reviewed matches ready to continue. Shelf Scan now finds far more of your books. Each spine is read on its own, so neighboring books mix far less often. Misreads, price stickers and publisher names now block far fewer matches. Titles missing from Open Library are also looked up in Apple Books. Spines the catalog could not check show Not checked with a Retry button. Add by hand can search the catalog by title or author. New installs start with an empty library.
