My book collection
I have been using the program to catalogue my book collection for quite a while and only recently decided to print my catalogue. The program worked very well, allowing me to choose the fields I wanted to include. I am very satisfied so far.

I absolutely LOVE this app!
I have been wishing for a tool like this ever since made my first book collection database in Excel 20 years ago, and now I have finally found it! It is beautifully designed, it's very intuitive and simple to use, it is easy and quick to add new books, and it has all the functionality you could wish for. It is also easy to personalize so that you only use the functions that you need, you can sort and organize your collection exactly as you please. And I LOVE that it has all the cover photos instead of just long lists of titles. I strongly recommend CLZ Books to all book lovers out there!

A serious time-saver!
It's a working quite well, thank you! I've managed to catalog over 160 books in just under 2 hours of time. With a collection exceeding 1500 books, this app is a serious time-saver! Out of these books so far, I've only found 3 needed a little extra love or manual attention. The barcode scanning is awesome!

Very useful
I've started the trial for the cloud version and the desktop version to see which I prefer. I might end up using the cloud version but still keeping the app on my phone as well as it's just more user friendly when in a book shop to open and check my library list.
Honestly out of all the apps I've used this one has been the easiest to get used to, add books to and navigate. As I've now gotten too many books that fit in my apartment I've found that it will be very useful to keep catalogues of what's in storage, what's in the apartment and what I keep at my office and lend out.

Wonderful product
I'm delighted with both Book Connect and now CLZ Books. Initial setup worked well.
I've entered almost 3,500 books in the database, with about 500 more remaining. Collected over more than 60 years.
Thank you for producing, maintaining, and constantly improving such a wonderful product.

The CLZ programs are among my favorites
I have used CLZ software for several years, for my audiobooks, and hard and soft covered books. Also, I use their software for all of my movies, whether it be DVDs, Blue Ray disks, or what I've bought on Amazon Prime Video. Of all the many software/apps I use CLZ programs are among my favorites. The book and movie programs are what I use to inventory my stuff.

No more duplicate purchases
Thank you for your time and patience with this. At first, I was not sure if I wanted to use this particular piece of software as I had been less than impressed with other brands, but after cataloging my collection, and now that this is done, continue to add to the collection as I add books—and to be able to see what books I have so I don’t duplicate the purchases.
This is the software I was looking for, and the tech support pretty much puts your brand over the top for me. Thanks again.

Very intuitive
Flexible and very easy to use. The user interface is very intuitive. It has had several nice and useful enhancements over the time I have been using it. Support, if and when you need it, it is fast and very efficient.

Great for keeping track of books
Barcode scanner fantastic. Good online database for manual search.
Update 6/23. Tech help prompt and responsive and App continues to be improved. Took 3 years to enter the thousands of books in our home library. Great having them at our fingertips. Now no second guessing about whether we've bought a book or read it before so, in addition to the unparalleled convenience our having the library on our phones we've saved more than it cost in not doubling up.

Fantastic
Had a play around to see how it worked and love that I can choose which fields I use. I do find when going back into a book I've already added can be a little confusing as there are multiple pages but I'm sure I'll figure it out.

Ottima applicazione
Ottima applicazione e soprattutto un eccellente servizio di assistenza, rapido, cortese e competente!

Love this app
I’ve been using this app for over a decade, and it keeps me from purchasing duplicates. Not only do I enjoy the book database capability, but I particularly appreciate the customer support. The two times I have needed help, I have received a response within 24 hours. They also update the app on a regular basis, so they are always working to offer an improved product. This is a great app for book collectors.

I'm loving this program
I've been taking more time to input my books, both physical and digital, into Book Collector. I've had this program for years and have used it in spurts but now I'm putting time into it. Thanks for creating this way back when. I'm more than happy to have a subscription. Thanks for your improvements and making this the best option to catalogue my books

Cloud access is useful when I'm at a bookstore and buying new books and checking my collection.

Best app ever!!
CLZ Books is my go to app for tracking my book libraries. I rely on it whenever I purchase new books or audiobooks to avoid duplicating purchases. I recommend the app to all my friends.
The customer support function is also outstanding. I recently had an issue and contacted customer support for help. They responded quickly and helped solve my issue. Having such customer support makes the app that much better.
