Latest software updates

Alwin and Team,
I've been using Book Collector for a number of years now and decided it was about time that I express my appreciation to you for not only developing the best "book software" product on the market, but also, for your continuing updates and frequent communications. Book Collector has more than met my needs for the 2,000+ books I've logged. So again, a well-deserved thank you to you and your staff.
P.S. I just recently purchased Movie Collector to log all of my DVDs and CDs. I'm very satisfied.

I Can't Imagine Better
This app is a robust, easy to use, companion to the desktop version of this book cataloging database. The support is excellent. Moreover, the communications with the firm's leadership are friendly, evidencing that the entire team likes what they are doing. — Bernie of Ohio on CLZ Books

This saves sanity
We have almost 8000 volumes in two houses so this saves sanity and for the most part duplicate purchases. I used to have a card catalog system, but with Book Collector I have books in certain rooms, in certain bookcases - really helps when you are looking for reference for a talk! — Ronda Barnhurst (USA) on Book Collector

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

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

Location field
My wife and I are using it to catalog our several thousand books. We really like that we could add a location field. That way we might actually be able to find a book after it's been put away. — Mike O'Kelley (USA) on Book Collector

The best and by far
I’ve tried many apps to catalog my books and Collectorz.com is the best, and by far. Specially for someone like me who has a large collection and a large wish list. The same apply for their movie app. It’s really great. — Daniel D on CLZ Books

6+ stars
I have been using Book Collector for a very long time now. It has steadily shown a continual process improvement and in my humble opinion is better than some of the large library cataloging system software my wife used as a librarian. Recently I just added Movie Collector to the collection software I now use and it is also a great product.
I highly recommend all of the apps Alwin and the folks at CLZ have developed. The interface is intuitive and easy to follow. The money spent on these programs is money well spent. I love the update program as it allows one to be absolutely sure that you are in possession of the latest version and fixes. My personal rating for these PROGRAMS is 6+ stars....
Thanks to all of the CLZ team. — Edward Fry (USA) on Book Collector
