Latest software updates

I just wanted to say that I just renewed my Collector software for books. One of the major reasons I renewed, in addition to me loving your product, is that you have THE VERY BEST SUPPORT i have ever seen in the industry. When I have had questions over the years, I have asked and you have answered quickly with comprehensive, specific instructions to help me fix my issue(s). Keep up the GREAT job and thank you very much for an excellent product. — Larry Fretts (USA) on February 27, 2017

Marvelous software program
Collectorz is a marvelous software program. It is so intuitive, beautifully designed and user-friendly. I have a fairly large library and I have never had it more cataloged and organized! — Dan G. Olson (USA) on Book Collector

FABULOUS!
Been using it for years. My book buddy and I can check which books we have in order to avoid duplicates. Also use it at the bookstore and library to see if I have it or read it. — Lucy Looney on CLZ Books

Great!
It's been working great for a few years now. My only comment would be the plethora of options available means I can spend even more time in my library making adjustments. — A Google user on CLZ Books

A real time saver
I love your programs (I also have the Music Collector). I have an extensive library of English and German language books. A substantial part of my library is reference material and Book Collector and its search features are a real time saver. I currently employ an IT student for data entry and proof his work on my iPad. The next step for myself will be entering all my eBooks. I use the iPad for my own data entry. Works great! — Irene Hahn (USA) on Book Collector

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

Greatest library software
I have a vast library and the thought of getting software to automate it had me horrified. This software was well priced and the customer service has been tremendous. They have gone the extra mile to help a non-computer guy like me to make sure I was able to get up and running. When I have had trouble because of my ineptitude the customer service has gotten back up and running again. I will never stop using this software. — Ron Clites on CLZ Books

Good App
I've been look for an iOS app for some time to keep a library of the books I've read, so when I'm in a store I can scan the database to see if I've already read it. Very frustrating to get home and find out I already have a copy. CZL solves that issue. The bar scanner is really fast and adding my whole library was done in 30 mins. — Riverdoctor on CLZ Books

Love this APP!
We have found this program to be so helpful to catalog our book collection. The app is a great addition to the software. I am able to add books when I am away from my computer and sync it when I am able. It also helps me to keep from buying a book I already own when I'm out book buying. This has saved me money. The other thing I have used it for is to check where in my home library a book is supposed to be when we can't find it. The pictures are so helpful. I can enter the books on the software the way they are positioned on our shelves and then scroll through the pictures on the app on my iPad to see what shelf the book we're looking for is and what books it is in between. This has saved us so much time. — HeritageCA on CLZ Books

Fantastic app for organisation
Makes sure I know what books I have so I don't buy twice! Also lets me be in control of my library. — Sherfazz on CLZ Books

Wonderful!
I have the CLZ Book Collector program on my PC, and sync my library to the cloud. I can then download my whole library onto the app, and have a handy reference for whether I already own a book or not. If I'm out and buy a book, I can add it through the app and sync it with my computer later. Fabulous! — Khatcher23 on CLZ Books

Handy when I'm book shopping
I use it to keep track of what books I have, so that when I shop I know if an interesting book would be a new addition to my library. I find it easy to add books by scanning ISBN bar code on back cover or inside cover, which works for almost all books. Older books (~40+ yrs) that don't have recognizable ISBN, I search by author and title then select to add (still relatively easy). In very rare cases I've added a book manually and included the front cover picture that I took myself. — C101481 on CLZ Books

I've been using this program for many years. Outside of professional library databases this is the best product out there. — Bob Kentner on CLZ Books

Best catalog app in the market
Lets face it, if something is good, like really good, its gonna cost something. I personally feel the 1 time cost to get unlimited space is so worth the money! And it's not even an arm and a leg cost. I love this app because im hoping to one day have Belles library from beauty and the beast so im gonna need not only a little more space but something to make sure im not doubling any of these books, and at just a little over 400 right now, i can say this app has definitely helped me avoid that! — Andi iRock on CLZ Books

Best app I have found yet

CZL Books
Greatest book collection library as I read many ePubs from the US Air Force Online Library. Keeps me from rereading books I have already read and helps me to select the next book I wish to read. Lot of PLUS PLUS BENEFITS in the program, sorting, logging info, etc. — Bob Pruess on CLZ Books

CLZ Apps
I have used the Collectorz software for many years on my PC and MAC. The use of their iPhone app has made the software even more valuable! I love knowing what I have in my library, or who has borrowed it right on my iPhone. I also love the fact that I can see my collection of music and movies in the palm of my hand. Good job guys! Keep up the good work! — K DaBear on CLZ Books

Essential
If you have a significant library you need an app to manage it, and this is the best I am aware of. — Mark Chiarello on CLZ Books
