"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."

"I couldn't let this year end without telling you how pleased I am with
Collectorz for Books. I am the "librarian" at Cedar Creek Battlefield
Foundation, one of scores of American non profits which memorialize
our many Civil War battlefields. I paid for the program with my own
funds, since CCBF operates on a shoestring, with most of our energy
and funds going to our effort to preserve what many consider "sacred"
land since it was drenched with the blood of our ancestors.
I deeply appreciate your unending quest to improve your already
tremendous product without gouging your current customers to acquire
the latest improvement, unlike some bigger companies I could name!
All the best in the new year. I'm glad I discovered you; it's made
cataloging our numerous holdings ever so much easier!"

"Dear Team at CLZ,
I can not tell you how grateful I am with the whole process. My laptop crashed and I lost all my data on the database. Weeks and weeks of work was gone. I contacted your Team desperately and explained the issue. It was like a breath of a fresh air, what an experience, patience and professional experience I had. My issue was resolved within few days and I got all my data back.
I can not thank you guys enough. Special thanks to Sytske Hermans. I can not say enough great things really.
Thank you so much."

"I use the book collector and am going to get the movie one soon as while I don't have as many DVD's as books, it's getting to the point where I don't remember what I have and what I don't. I've printed out the book list and take it with me to booksales now to avoid duplicates."

You guys rock
"Thank you, thank you. All 180 books (in cloud, oops haven't synched my desktop in a while, shame shame on me) came in successfully. Greatly appreciated. You have a great evening and tell Alwin to take you out to dinner for being so awesome at supporting customers.
As always, you guys rock, and keep up the great work. Looking forward to renewing my subscriptions and trying out the new desktop app features very soon."

Having a blast
"I bought Book Collector Pro Edition for my Mac and so far, it has been a godsend to someone like me who has about 3,000 books in my personal library. I also purchased a CLZ Barry to conveniently scan the books and add them to my collection. I’m getting more and more familiar with navigating the Book Collector and I'm having a blast with it!"

Saving me money
"I have a collection of several hundred books. Most of which are genealogy and history books. Many have similar titles. In addition to saving me money by preventing from buying a book that I already own, Book Collector provides me quick access to the contents of my books when I am trying to research an ancestor or historical event. The Notes Section allows me to add my own notes concerning a particular book. Also when someone ask me where I got a particular book, I able to tell them along with the price I paid. It obvious that a lot thought into the design of this program."

Love the way it works
"Have just finished the first part of my collection. Now have 6,830
books catalogued. Just thrilled. Somehow the remaining 2000+ doesn't seem to be so
daunting. Just love the way it works. OUTSTANDING! Trying to persuade all my family and friends to get onto Collectorz
early! Always enjoy your FB posts. Keep them up."

"Thank you for your speedy responses with answers to my questions. As you explained, my scanner works fine with your software and is making logging my books seem almost magical. My daughter introduced me to your software a couple years ago, but I was slow in getting started – shame on me!
One reason your software is such a gift to me is that about 11 years ago while logging information on about 1500 books on index cards and on my computer, a flood hit our area and our home was affected. I lost about 700 books to the flood and never went back to update my personal library. Since that loss, I’ve purchased many more books to add to those remaining – and inadvertently bought some of them more than once, hence my need for better organization of my books – and with your software I’m quickly updating my records.
Within a short period of time I used my scanner to log nearly 400 books and have asked my granddaughter to come and help me with the rest of the project in a few weeks after she graduates from high school and before she heads off to college. We look forward to working on this project together. What a treat it is to watch those books jump onto the screen with all pertinent information, just by using a scanner and making a few clicks on my keyboard to save what popped up.
I was pleasantly surprised when seeing more book and author details than I was aware of, too – including links for information on Wiki... The list is great and has such a great user-friendly sorter by title or author. When browsing around and clicking on the Images tab and seeing the books lined up on book shelves, I actually leaned back and laughed with surprising joy. Clicking on the Cards tab showed me the little cards complete with each book’s information, and I was amazed.
I’ll highly recommend your software to others and want to thank you so much for this delightful program."

Saved the day
"My wife and I are Seniors and use your Book Collector all the time. We read e-books and have over 800 in our library.
As Seniors, we had a hard time remembering which books we have read
and many times we would download a book and get half way through it
and then realize we had already read that book.
Then we FOUND BOOK COLLECTOR and it sure saved the day, week and
We have it on our tablets and desktop computers so everything always
stays up to date.
Thank you very much."

"Thanks for all your help and your wonderful programs. I have worked with professional cataloging s/w for 15 years (I catalog at the family history library in salt lake city, utah), and so I know some good s/w when I see it, and I just love this s/w for doing the cataloging of my books and videos and things back home."

If you wanna best...
"The best of the best I've ever seen or used. Everything works as
described. The OSX version is highly complex (mean: it knows
everything), yet very easy to use, and all customizable! All you can
try free with the sample database, or even with 100 own books.
Infinite easy to sync between OSX and iOS applications. The mobile
application can also scan the ISBN, so you can promptly import a new
book. If you do not find a book in the central database, you can to
upload, and after that everyone reach it. This is great! On the other
part, the mobile version is always with me, so I know what I already
have and what's on my wish list. Anywhere and anytime. This is
But the most superior is the SUPPORT. They are fast, nice, helpful,
effective. This is at least 6 stars (from 5)!"

No more duplicates
"My husband gave me book collector as a Christmas gift to
catalog my collection of 4,500 books. When I went to book sales, I sometimes purchased duplicates of books I already owned. With the export function of Book Collector, I put a list of my books on my cellphone and now check the list before I buy another book. In addition to organizing my collection, your product has saved me from wasting money on duplicates.
Thank you very much for your help. Your directions were clear and easy to follow. Book Collector is now
correctly installed on my new computer. I appreciate your expert

It is a wonderful program that you have designed and I really love having all my cookbook collection listed clearly in one place and also makes for easy reference.
