Here's what customers have said about CLZ Books

Fantastic app for organisation
November 30, 2016
“Makes sure I know what books I have so I don't buy twice! Also lets me be in control of my library.” — Sherfazz

“I have the CLZ Book Collector program on my PC, and sync my library to the cloud. I can then download my whole library onto the app, and have a handy reference for whether I already own a book or not. If I'm out and buy a book, I can add it through the app and sync it with my computer later. Fabulous!” — Khatcher23
