The best
I have been using CLZ since before it was CLZ. Anyone remember KIC? I will continue to use CLZ as long as I collect books, movies, comics, and music. Not a gamer so I don't need that app. — Ron Weekes on CLZ Books

AWESOME program
THANKS for helping! I just KNEW it had to have an easy way to do it because the program is AWESOME. Have to take a quick minute to say I'm SO impressed and as a programmer myself, I usually find things I want to change, but not this program. It is REALLY well designed and so configurable.
My husband has been pushing me to go electronic with my catalog for a long time now and I was VERY resistant. Love the tactile card catalog. But after using your program extensively yesterday and finding all the new/improved features, I have to admit that my first reaction was "It's time to have a bonfire with my old paper system!" Actually, they'll all go into the recycle bin. Much better for the environment that way. There is just so much more that your program offers that the paper cards just can't do.
It is rare to find something programmed so well that is so user friendly. And it's made my life a lot easier. I have a LOT of books and because of the location field, we can find things a lot faster when the kids need something for a school research paper. I'm in the middle of cataloguing a huge collection in my spare time, and it goes so fast! A click or two and it's in with all the data. And the image of the cover is great when trying to locate it on the shelf! — Sarah Foster (USA) on Book Collector

Easy to use, syncing works well
An easy to use database for a book collection, which extends to eBooks as well as printed books. Syncing between devices is efficient, and looking up information about books - even old books before the days of ISBN - is fast. The interface is attractive. Where available, the app adds cover images automatically - but this is not always possible with older books. Books can also be added manually. — Michael Cayley on CLZ Books

Just what I needed
I probably have close to 500 books in my library and felt the need to catalogue them. This app is what the doctor ordered. — Sonny Barber on CLZ Books

Easy to use
Finally there's a quick and easy way for me to catalog all of my books. It's so easy to use. My books are organized and easy to access. So now when I go to bookstore, there's no chance of buying repeats. I really needed this. — Tanya Perry 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. — A Google user on CLZ Books

Absolutely love this app
Really simple to use. Just scan the bar code and it's in my collection. Syncs between devices, so now I can see my collection in the bookshop. Can also create a wish list in the shop! — Anna Martin on CLZ Books

PHENOMENAL
I use the CLZ apps for my book, movie, and game collections and they are PHENOMENAL. I can't praise them highly enough! It has rescued me so many times from almost accidentally buying a book I already own. It's so easy to just scan the UPC to add to your collection (and you can scan a whole stack without stopping to hit "add" every time), or you can manually create an entry in the rare instance that it isn't in the database already, filling in as many or as few details as you care to.
I love that you can mark when you've read the book, give it a rating, add a little note/review for yourself, and so many other things. The features are really thorough. You can even mark things "not in collection" (for example, a book you read but no longer own or had borrowed from someone else), or add them to a wishlist. You can backup your entries to the cloud for easy transfer if you get a new phone or whatever.
The only downside is that you are limited to 100 items unless you pay to expand to unlimited storage, but I thought it was worth the price to compensate these developers for their great work. — Kelly Gorga on CLZ Books

The best catalog app
I have had the desktop version for many years and now the mobile app and I love both. I don't know what I would do without them as I own thousands of books. This to be the best way to catalog them including ebooks. — L.M. W. on CLZ Books
