So professional
This is the first app for cataloging books that is so professional and easy to use I give it 5 stars. — Robin Shertzer on CLZ Books

I Can't Imagine Better
This app is a robust, easy to use, companion to the desktop version of this book cataloging database. The support is excellent. Moreover, the communications with the firm's leadership are friendly, evidencing that the entire team likes what they are doing. — Bernie of Ohio on CLZ Books

Great app
Not the prettiest app, but the scan function is way superior to every other book cataloging apps I've tried. — Browniecheng007 on CLZ Books

A joy to use
I downloaded a dozen or so book cataloging apps to try them out. Mostly, they went from bad to worse. CLZ Books was superlative: user-friendly, smart, fast, and intuitive. Keep up the good work! — Sistah Eve on CLZ Books

Wonderful! Catalogue your books
This and its desktop counterparts go from strength to strength. They interact seamlessly via the cloud and hugely facilitate the making and keeping of a book catalogue. Since you can carry the catalogue in your pocket it will pay for itself in prevented duplicate purchases. There is room for improvement; I would happily pay a modest amount extra if Dewey numbers were routinely included in the online catalogue; at present the majority of my non-fiction books have them, but many don't. The subject indexing field is chaotic and anarchic. It seems that users can dream up their own format for each subject, with the result that one subject may have several labels differing only in punctuation or some other trivial respect. There must be a better way. The handling of diacritical marks is deficient. The book price fields give no indication of the currency: this makes the field essentially useless if one buys in several currencies. A way of printing labels including spine labels would be a useful addition. However the app is continually being improved over the years. Support is excellent, with prompt and intelligent responses. It's by far the best solution I know of for a private collection or small library. — Leighton008 on CLZ Books

Best I've found
While it's not perfect, this is the best application I've found for keeping a book catalog synchronized between several Mac computers, iPad and iPhone. I recommend it; if you need very detailed records, the Mac or Windows application is more complete and works perfectly in conjunction with this one. Barcode scanning for ISBN works well; note that some books (mainly from the 1980s & 90s) have a UPC code instead, which doesn't identify the book. — Anton Rang on CLZ Books

Awesome
We have spent many hours cataloging books in our book collector software. The software is awesome! Really, one of the best I have ever used and very affordable. It is so simple and intuitive. My seven-year old does a lot of cataloging and really enjoys it. She often says she wants to be a librarian. ;) Well done! — Erin Daly (USA) on Book Collector

A Great Program
This book app is worth every cent (especially if it can prevent you from buying duplicates!) and with the new update has become increasingly user friendly. The design is very laid back and easy to use. Definantly the best book cataloguing app out their. One feature I would like seeing however is database totals so I can view the worth of my collection. — LongHairedFreakyDude on CLZ Books

CLZ
I have the full version of Book Collector and Music Collector therefore have both CLZ's. The good thing about these programmes is they have NO missing artwork, and the support is amazing. Since buying these programmes I have stopped buying duplicates.
If you like to catalogue books, music, comics etc,etc then these programmes are for you. — Amdramsing on CLZ Books

Oh happy day!
I have been searching for a broad and diversified book cataloguing program, at one time beginning to design my own, but think you have come up with everything I am needing to include.

An academic colleague referred me to you - oh happy day! — H Adams on Book Collector
