Latest software updates

I absolutely adore your software, and have had a blast adding my nearly 3,000 books to my database. (I've included a pic of one wall of my library.) It's fantastic to be able to check the mobile app while out shopping, to make sure I don't buy a duplicate of something I already own.
I wish you continued success, which you greatly deserve, because you've nailed it with the library software.
I have recommended your apps to many people – anyone who collects books, music or movies – and will continue to do so, although I think I’m too old to know anyone who collects comics or video games. LOL

This app is excellent
It allows me to scan in most of my book collection using the ISBN barcode. A small minority of my collection is not in the database yet, but inputting these is not difficult. Finally, I can download a custom CSV of my library to make a spreadsheet. The app interface is efficient and pleasant to interact with. This is app is an ideal took for a book collector like myself to use to catalog a personal library. — Sean Sovine on CLZ Books

Se você tem livros definitivamente precisa de um aplicativo para facilitar a organização e a localização - e esse não tem concorrentes. Uso versões para Windows, Mac, iPhone e Android, atualizo ou introduzo dados em qualquer um deles e sincronizo via nuvem nos demais. Excelente. — Angelo Salignac on CLZ Books

The very highest quality
I am a retired librarian doing a favour for an old friend. And I have to say that, from day one, I have found your software to be of the very highest quality. Congratulations on a superb product!
I should also add that I have found your after-sales service team to be most helpful and efficient.

Quality
If in Australia I would only use the cloud version. But I particularly like the way the phone apps, the cloud data as well as the laptop data base all sync so easily.
Having had 5 friends in different locations add to the the library over the past few months we would conclude overall that the software is very good. Each individual found their preferred way to add books and search for covers. Any questions we had we were so promptly answered... this gives such confidence in the quality of the software and its future development. When I get to the school in Kenya it will be interesting to to see if the situation is going to be suitable to do all the school borrowing from the laptop library data base. Electricity for charging can be intermittent. We may need a paper system as well. — Max Sargent (Australia) on Book Collector

Best Book Organizer on the Market
I’ve tried two other apps to keep track of my huge book collection and have been disappointed... until now! Finally, someone who gets it! Easy input by scanning the ISBN barcode (for most books), or typing in the title. Contains more information than other apps by linking to the Library of Congress. User friendly in that all data can be manipulated to meet specific requirements. Thumbnails are included and can be changed if needed. Pick lists are editable, too. Try it, you’ll like it! — Consumerpaul on CLZ Books

Great stuff
You've added the resize window to image for every image, wicked! I nearly missed it as it wasn't mentioned in the "what's new" and fixed all those damn toolbars too. Really great stuff and thanks to all. — Geoff Owen (United Kingdom) on Book Collector

Great app
This app is pretty great. I only use it to track the books I’ve read not necessarily books I actually own. I found buying books kinda of wasteful so I just borrow books from the library. — mmw604 on CLZ Books

A great app
I bought this up as a surprise for my husband (a voracious reader). I decided to create a digital catalog of our home library and it makes life so much easier. A great app and a great customer support team! — Olga.I.A on CLZ Books

I love this app
Before CLZ, many times I did not know what I had when I went out to buy books, comics, etc. Now I have the option of checking my collection instantly to prevent any purchasing mistakes. That is invaluable to me as a serious collector. It's uses continue to improve my collecting life a few years after first getting this app. — A Google user on CLZ Books
