Latest software updates

I would like to congratulate you on recent changes. The new design for the Book Connect is excellent, it is cleaner and crisper, plus it is faster to use. That is always a plus. Additionally, the changes to searching in the Core are beneficial as well, much faster, especially the new integrated search blank (author and title together), plus the way we can now see more information about each book in the Core. That is a big help in selecting a good volume out of many. Bravo! — Debbie Cox on January 10, 2018

Life changing app for bibliophiles
This app does what it says it will. I have been using it for ten years now and it has changed our lives. We now know what books we own and the value of our collection. It doesn’t put the information in by itself but it does keep it safe once you have entered it. The wonderful support provided by the developers makes me weep that I can’t get the same from work related IT team. Thank you. — Ozetrvlr on CLZ Books

Absolutely amazing app!
It is so useful when it comes to shopping, since I own a lot of books. It's easy to use, but is organized well. I hope to unlock the whole database soon when I get the moneu to unlock it- I know I have more than 100 books! It'll be worth the investment for such a time-saver. — Eddie Wright on CLZ Books

Online database finds virtually every book
Handles thousands of books without any problems and their online database finds virtually every book I throw at it. Their other products are just as good. The desktop versions also let you configure the fields and display to suite your specific needs. — A Google user on CLZ Books

Great home cataloging system for personal library
In process of loading over 2200 printed books into CLZ Books. Learning curve is fast. Great features and able to customize for my needs. I bought both PC and IOS versions and the latest update was to auto sync. Customer and Tech support tops also. Great job. — Arm mike on CLZ Books
