Fabulous app

This app is brilliant for recording books I have read or want to read. I no longer buy books I have already read

Best out there

This is by far the best book library on apple. So easy to add books to library and lots of options to get your library organised the way you want. Worth the subscription!

My Go-To For Years

Iโ€™ve used CLZ Books (and Music) for years. Itโ€™s the simplest way Iโ€™ve found to keep track of my collections. The camera driven ISBN scanner is brilliant. And in the rare case it doesnโ€™t find the book Iโ€™m adding, the manual entry method is easy to use as well.

Donโ€™t let โ€˜simpleโ€™ put you off though. The app allows you to filter as many ways as you can imagine. Its ability to track books series is excellent and extremely useful for me.

Highly recommended.

Smooth Transition From Readerware

Just moved about 4000 entries from the now discontinued โ€œReaderwareโ€ and the move could not have been easier using the CLZ tool. Effective concept of Core Collection is well considered. More to come as I explore

Disappointing

Not many of the independent books I have in my library that have isbn numbers are findable and i have to enter the majority of information myself and I cannot include pictures of the book, so itโ€™s a blank cover. Very disappointed. Will start looking for another way to catalog my books.
