Love this app
I absolutely love this app. Easy to use and helps me keep my growing library in order plus I can take it anywhere and if I come across a book that I'm not sure whether I have it or not all I have to do is search it in my app. Love it!! — Brenda Cosner on CLZ Books

Always have my list with me
I have this software for my 800+ books. A great way to always have my list with me, to prevent the occasional "double purchase" of a book. I recommend to you for your library. — Thomas L Hiegel (USA) on Book Collector

Makes the lending of books a breeze
As Library Coordinator for our chapter of a national environmental organization I use Book Collector to stay organized. The software makes the lending of books a breeze. We have over 230 books which some of your respondents would scoff at but, since I haul the books to monthly meetings, it is plenty big enough.
I value Book Collector highly and rely on it to keep track of all details of running a much used chapter library. Thank you and keep up the good work! — Virginia Watson (USA) on Book Collector

A great product
We are using this at our car club Library with 5000+ books and 500+ lenders. A great product, at a very reasonable price, easy to use, easy to maintain and runs on machines with minimal resources.
I recommend this product to anyone wanting a maintain a small library....and I am an IT manager at a library for a living. — Neville Butler (Australia) on Book Collector

Just what I needed

Saves me from buying duplicates
I have been using this software for years to track my library as well as all books given as gifts. It saves me from buying duplicates. I also know exactly which shelf to find a book on. — Carol Bostian (USA) on Book Collector

Paid for itself
Fabulous program that's already paid for itself in saved duplication. As a portable catalogue of my library I couldn't ask for better. The seamless integration between phone app and desktop is fabulous. — Micheal O Doibhilin (Ireland) on Book Collector

Marvelous software program
Collectorz is a marvelous software program. It is so intuitive, beautifully designed and user-friendly. I have a fairly large library and I have never had it more cataloged and organized! — Dan G. Olson (USA) on Book Collector

FABULOUS!
Been using it for years. My book buddy and I can check which books we have in order to avoid duplicates. Also use it at the bookstore and library to see if I have it or read it. — Lucy Looney on CLZ Books

Great!
It's been working great for a few years now. My only comment would be the plethora of options available means I can spend even more time in my library making adjustments. — A Google user on CLZ Books

A real time saver
I love your programs (I also have the Music Collector). I have an extensive library of English and German language books. A substantial part of my library is reference material and Book Collector and its search features are a real time saver. I currently employ an IT student for data entry and proof his work on my iPad. The next step for myself will be entering all my eBooks. I use the iPad for my own data entry. Works great! — Irene Hahn (USA) on Book Collector

Greatest library software
I have a vast library and the thought of getting software to automate it had me horrified. This software was well priced and the customer service has been tremendous. They have gone the extra mile to help a non-computer guy like me to make sure I was able to get up and running. When I have had trouble because of my ineptitude the customer service has gotten back up and running again. I will never stop using this software. — Ron Clites on CLZ Books

Fantastic app for organisation
Makes sure I know what books I have so I don't buy twice! Also lets me be in control of my library. — Sherfazz on CLZ Books

Wonderful!
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 on CLZ Books

Great App
Makes organising my library easy. — Ian Gwilliam on CLZ Books

Handy when I'm book shopping
I use it to keep track of what books I have, so that when I shop I know if an interesting book would be a new addition to my library. I find it easy to add books by scanning ISBN bar code on back cover or inside cover, which works for almost all books. Older books (~40+ yrs) that don't have recognizable ISBN, I search by author and title then select to add (still relatively easy). In very rare cases I've added a book manually and included the front cover picture that I took myself. — C101481 on CLZ Books

I've been using this program for many years. Outside of professional library databases this is the best product out there. — Bob Kentner on CLZ Books
