CLZ Books

Effortless cataloging for serious book collectors

CLZ Books is designed for readers who are tired of juggling spreadsheets, sticky notes, and half-remembered titles. Its focus is simple but powerful: turn your entire library into a clean, searchable, and richly detailed catalog.

The star feature is the barcode scanner. Using your device’s camera, you can add books in seconds by scanning ISBNs, and the claimed 98% success rate feels realistic in practice. For older or obscure titles without barcodes, you can search by author and title, pulling data from the CLZ Core online database. This database is impressively complete, automatically filling in cover art, publisher, publication date, plot, genres, and more.

Once added, every entry is fully editable. You can tweak metadata, upload your own cover images (front and back), and append personal notes such as condition, location on your shelves, purchase details, or whether a book is loaned out. Multiple collections, presented as neat tabs, are handy for separating physical books from ebooks, family members’ libraries, or items for sale.

Customization is a major strength: view items as lists or large cover cards, sort by almost any field, and group your collection by author, genre, publisher, or even storage location. CLZ Cloud sync keeps your library backed up and consistent across devices, and makes it easy to access your catalog wherever you are.

The subscription model—£1.75 per month or £17.50 per year after a 7‑day trial—may deter casual readers who only own a few shelves of books. However, for collectors, librarians, or anyone managing a large or growing library, the price feels justified by the time saved and the level of control offered.

CLZ Books is a polished, feature-rich organizer that genuinely streamlines book collection management.
