I have been so happy with the book collector software, especially since it can be synchronized with information on my iPhone.
It is wonderful to have a portable listing of my book collection. I commend you and your team for development of excellent products.

Exceeded my expectations
I have been using Book Collector for a couple of weeks now and I must report that it has exceeded my expectations in form and function. It is a well thought out program that is comprehensive, intuitive and aesthetic. The customization options are awesome. Kudos to you for coming up with such a program. This is exactly what my book collection was screaming for. Thank you. — Christopher R Carey (USA) on Book Collector

Beats them all
I've used several other book collection programs over the years and Book Collector beats them all in every category. I'm very satisfied with your product and intend to be a user for very long time. — Darrell Poteet (USA) on Book Collector

The best cloud database I’ve found!
For years I’ve tried several systems to manage my book collection database. I’ve created Excel & Access spreadsheets & databases nothing seem to fit the bill. Spreadsheets although functional lack of visual component that is important to manage your collection. Collectorz is the best app which allows me to store my database in the cloud and access it from all my devices! — applenicolo on CLZ Books

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

You need this app!
Have a book collection? You need this app! I've been a user since 2009, and it is an essential program. The app's functionality is a welcome addition to an awesome program. — Bill Sawyer on CLZ Books

Well worth the money!
This is an excellent app! It makes physically organizing your book collection on shelves a breeze. Plus, no longer will you have to get up and search through your collection to find if you have a title by a certain author. You can scan your collection in a matter of seconds in order to find out.
Since I have it on my phone as well as my iPads, I can use it in the bookstore, too. No more buying an older title only to find out I had purchased it years before. Support is excellent as well. I have the CLZ Movies app, too. I love them both! — Zircon_215 on CLZ Books

Books and DVDs
I created databases of my books and DVD several years ago (OK, decade ago) using MSAccess. It left a lot to be desired. With this app and CZBarry I entered my entire book collection, 1200+, and my 980+ DVD collection in less time than entering the pertinent data for maybe twenty books. I doubt I spent but two hours on the lot with the exception of my pre-barcode era books. Hey, a book printed in 1908 won't have that.

The app does take some learning and I'm still not up to speed with it. But without it I'd still be scanning slip covers and typing into the wee hours of every day to get everything entered to the extent this app provides. — Floyd Mack (USA) on Book Collector

I just thought I would drop you a note to say how pleased I am with your software. I have previously fiddled around with several competitor products for maintaining a database of my book collection - including apps which run on Android devices as well as Windows. I came upon Book Collector for Windows last week, tried it, and found that it is easily the best product of its class - absolutely well worth the money you ask for it (and probably much more!).

I can genuinely say this is one of the best thought out database systems I have come across in quite a long time, and the all-important user interface is really well designed indeed. It is truly a joy to use & does everything I need. The automatic data-entry mechanisms & scope for maintaining pick lists etc are exactly what is required to facilitate the arduous task of data-entry, and the facilities for listing, displaying images, sorting, and printing are superb and very intuitive.

I found that the competitor products quite often failed on automatic lookups via ISBN (particularly those systems designed in the USA), whereas Book Collector has very rarely done so up to now- I'm amazed at how often it finds details for books I have which are 50 years old or more & don't show an ISBN (or even an SBN!).

So congratulations on a really brilliant piece of software - I would recommend it to anyone needing to catalogue their book collection. — G C Pearce (United Kingdom) on Book Collector

Convenient scan using mobile

This is a really useful app
If you have a book collection and it is not easy to take the books to the Computer, you can take the database to the books. — Adam Sherlock on CLZ Books

The app works really well and is very intuitive to use. I have a significant book collection and it has prevented me from buying duplicates and allowed me to purchase a book in better condition or a different edition. It is an essential app for any book collector. — Listenip on CLZ Books

Best app I have found
I have tried a number of apps to catalogue my book collection, and this one is the best I have seen. It has some minor things that could be better, but it's well worth the price. The support has been very good also, responding quickly when I had a question. — Kent231 on CLZ Books

So easy so good
Only just started using it but it's so easy and intuitive, I was looking to catalogue my extensive book collection manually on a spreadsheet, but this finds your book via barcode and more importantly by author title, then displays them beautifully in list or carousel format. Highly recommended and may be useful for insurance purposes. — Cevpip73 on CLZ Books

Book nerds favorite app!!
I am a college professor with a decent book collection. I have never really left a review this extensive before but I had to! I LOVE THIS APP!!! I haven't used Mac version so I am bit of a novice. I had been searching and searching for a book database app to figure out what books I have. It's easy to use, just scan and upload!! — SoCame DaGoddess on CLZ Books

If you have a large book library, you need this app!
I have a huge collection of books and I just recently found out about this app. It's a great app to catalog your book collection. I have bought books in recent years, only to discover I already had it in my collection, but not anymore. I can now quickly check to see if I have a book. It's a great app!!! Two thumbs way up. — trekker61 on CLZ Books

Great App
I have used CLZ book collection for years but this app (on my iPad) is so much better than the previous versions I used on my desk top. It is easier to use and can be saved in the cloud. — genipgal on CLZ Books

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 book 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 assistance. — Susan Godlewski (USA) on Book Collector
