Latest software updates

Just a short note to tell you I would be totally lost without your program (Book Collector) with 2000 books on the shelves it would be impossible to know where to find a specific book, and I would finish up with a lot of doubles on my shelves.
Thank you very much.

You are the best
I could not manage my collection without. I love the option to scan a book in the store and find out if I already own it. Happened a couple of times before I converted my collection to your program. — Frank Bernhardt (USA) on Book Collector

Easy to use system
I finally found an easy to use system for cataloguing my specialist book collection. I am sure I only use a small proportion of its capabilities but it’s straightforward and the customer service is excellent. — Toucan 2oo (United Kingdom) on CLZ Books

It works!
I just got this app and I love it! It was rocky setting up some of the books I have but didn’t check my email which had a welcome note with clear instructions on how to add books! I contacted customer service with some search questions and received a nice response very quickly. It’s not an automated reply! I even deleted a different book tracking app because this one is easier to use and faster! Feature I like are seeing books I own that are marked read or not read, the ease of scanning. and the folders for categorizing! Oh and the friendly customer service! Thank you! — LisNeal on CLZ Books

Textbook catalog
I am trying to catalog my husband’s library of about 2500 textbooks in different languages. I searched all over the web and finally came upon CLZ. This sounded just like what I needed. I emailed them to inquire about this and got a positive answer in less than 24 hours. We bought the app and I started to catalog all the books. By now I have entered about 1150 and moved to the cloud. Every time I had a question I got an answer in less than 24 hours. Their support staff is excellent. This is really a great app and I couldn’t be happier with it. I highly recommend it to anyone who tries to catalog their libraries. — ollldie on CLZ Books

Un team di sviluppo molto disponibile
In assoluto il miglior programma+app per la catalogazione e la gestione delle biblioteche personali. Utilissimo avere sempre a disposizione in mobile le proprie raccolte. Aggiornamenti costanti e un team di sviluppo molto disponibile. — stefano stefanutti on CLZ Books

Great book catalogue
Love working with this app. Books can be entered by scanning their barcode, so it’s a powerful bookcataloguing system that’s very quick and easy to use. I make heavy use of options that allow you to personalize the settings and stored details, so it’s tailored to my needs.
Over the 7 years that I’ve used this app, I’ve seen lots of improvements. The developers are in-tune with their customers—if we ask for new functionality, it’s actually considered and often implemented. I even had the owner email me when I had an issue! — Kxt213 on CLZ Books

Highly recommended
Easy to use, extremely detailed app that allows me to keep my library nice and organized... not to mention, keeping me from buying the same book more than once. Highly recommended. A++ — Rodrigo Mendonça on CLZ Books

What a joy
So far I'm enjoying the app. To be honest, haven't really explored the app much to know what it will or won't do. But I do love always having my wishlist handy. — Robin Clark on CLZ Books

Wonderful software
This software has been wonderful for me - I have over 6000 books and this has made cataloging them much easier. — Randall Sykes (USA) on Book Collector

The best one
For a book organizing app, this is the best one I have found so far. Its ease of entry is well done, and getting your collection or inventory in this app is quick. This app deserves 5 stars for its function, and another 5 for its support. My initial review asserted a critical error against the app, when in fact it was mine own ignorance. These folks care about your experience, your privacy, and the app. — Spencer Burton on CLZ Books

My collection at my finger tips
Just download this app today but I truly appreciate how functional it is. Let me preface this by saying I did purchase the sub so I have both the scanning and cloud storage. I estimate that I have nearly 1000 books in my vast collection and often can forget which series I might have missing book in. Now I can keep everything at my finger tips! — Mara Jenkins on CLZ Books

I love this app
It helps me to keep my library in order and keeps me from buying the same book twice. I want to give a special shout out to Alwin in support for working with me to fix some issues that I had. Great support and great app!! — Morgan Holmes on CLZ Books

Absolutely superb
I am a professional library worker and this app holds its own against our system. Love the way you can adapt it to your own individual needs. — A Google user on CLZ Books

I love this app
I use it daily to manage my extensive book collection. It has very many useful options for sorting your books. It also has an option to add your thoughts on the book such as a rating, whether you have hauled or unhauled the book, when you read it and purchased it etc. Excellent app I have been using it for several years now. — Sarah Barden on CLZ Books

Perfect app, makes things so much easier!
As someone who is always buying books, and couldn't keep track of what I had, this was a must have for me! You can mark them as part of a series, and what order they go in, you also can edit any field to what ever you want if you want a different way. Now I always know what books I have in a series and never bought a double again! I've enjoyed it so much I use their Movie app too, and subscribe to the online service for a version of both on my laptop! — Rob Conley on CLZ Books

Love this app
I love this app and have been using it since its inception years ago. It's a great ways to organize and track all the books I buy and read. It has evolved a lot over the years and is continually getting better. The developers are very attentive to detail and very responsive with support and even suggestions. — John Barber on CLZ Books

Love this app!
I use CLZ books to manage my quilt books library. It helps me avoid buying duplicates which is good for my wallet. It’s also easy to add new purchases to the collection. Thank you, CLZ, for keeping me organized!! — JCquilter on CLZ Books
