Superb!
So far I'm able to scan my books and list them. This app is what I need. Extensive library! I'm just getting started. — A Google user on CLZ Books

Great library experience
More than 15 people who are on our Library Committee and staff have looked at our 1500 book catalog in CLZ Cloud and are very pleased with it. To a person, they have said how user friendly they think it is. I am delighted since there were several people who questioned why we needed a catalog. You know how some older people are about change! I am an older person too but I am thrilled to offer your product as a great improvement to our library experience. Just think, we can check for books in our retirement community's library from the comfort of our own apartments and cottages! — Betty Iwan (USA) on Book Collector

The BEST book cataloging software
I have used many book cataloging softwares ( including Library Thing). Book Collectorz is the best because:
1. It never, ever, ever, ever hangs
2. Customer support is top class
3. Deeply customisable
4. Available and syncs across all platforms
5. Very fast
6. Includes the 'Book Lending' feature
7. Very low cost for such a feature rich and solid software. — Param96 on CLZ Books

Library of about 5,000 books
I have a library of about 5,000 books. Book Collectorz is fast, reliable, flexible, and well-supported (including regular updates). I have used it for 10+ years. Five Bright, Shining Stars. — Sterling Sunley on CLZ Books

User since 2014
I’ve been collecting books my entire life and always wanted a library database like my local library. However, despite my best efforts, cataloging everything in excel and FileMaker Pro took forever and lacked the functionality I craved. I joined the Navy, and while I was in boot camp, my house burned down. My books were in the basement, and were destroyed by the water used to put out the fire. My family looked for a way to easily track my books for insurance purposes, and they found this app. This app answered both their needs and my needs. As I worked to rebuild my library, I kept buying duplicate books since I had a hard time differentiating the books I had lost from the books I had repurchased in my mind. I am now back over 6000 books and counting and I rely heavily on this app as well as the desktop version to keep track of my library. Sure, the core doesn’t have the most accurate or cleaned up data available and many plots are missing, but that allows us the take the data provided and make it our own. It’s a pity they had to change to a subscription service, because whenever I go to book stores or sales, I’m always suggesting CLZ products to my fellow patrons.
The barcode scanner saves me tons of time. — Hale.Yeah on CLZ Books

Greatest software for book lovers
Began with CLZ over 4 years ago. Took time to load in my library, but since then adding new books has been very simple. Updates are frequent and each one has been useful. I love keeping my book lists up to date and especially appreciate not buying duplicates anymore! — halftracker on CLZ Books

Great product!
I have about 3500 books and cannot remember where they all are. After searching extensively for a REASONABLY PRICED product to use to catalogue my library, a friend who is a librarian told me about CLZ. Wonderful! Don’t use it every day, but it is invaluable when I do. — Preachean on CLZ Books

My library
I have been using this app for several years. It is continually improving, and provides for a very comprehensive database of my large number of books. Easy to use, add books, and access details of my library. — Steve Harper on CLZ Books

Excellent way to organize your books
With this app, you will always have the titles of the books you have read or want to read in a very organized and easy to use format. No more going to the library or book store and not remembering if you already read a particular book. — Richard from Nevada on CLZ Books

Book library
The app is truly amazing. It’s intuitive and easy to use. Not only has it allowed me to (finally)stop buying multiple copies of the same book, but I’m now able to find the location of a book in my library quickly. — artbookaddict on CLZ Books

The best book database ever
I have been using it for over 5 years and love it the mobile app is so handy for checking to see if I have the book already in my library. And their support is the first-rate problems solved very quickly. Highly recommend. — woody161051 on CLZ Books

Best I've found
I have used several apps to keep track of my library over the years, and this has been the best that I have tried. They keep adding features to make it better. — Kent231 on CLZ Books

Truly Effective and Intuitive
CLZ Books via CLZ Cloud works seamlessly with the desktop Collectorz Book library management system. Excellent software backed by astonishingly swift and effective technical support. A great company with which to deal. — MikeB1946 on CLZ Books

Keeping track of your books made easy
Great app to keep track of your own books and the ones from friends or Library you’ve read. CLZ Support team actually listens and responds to individual clients as needed. The app continuously improves from one version to the next, based on their expertise and the feedback they get. Worth the investment! — mikki200382 on CLZ Books

Can keep track of all my books
Also it is great that I have the list of book borrowed from the library so I do not bring away duplicates of ones I have already read. — Barbara Leonard on CLZ Books

A great app with brilliant support
This is without doubt my favourite app. It’s visually intuitive, easy to use and enables me to sync my library across multiple devices. The support is also exceptional - I had a problem after downloading a software update which Alwin responded to promptly and efficiently. He told me the day and time the problem would be solved and it was. I’ve always recommended this app to friends and I’ll continue to do so. — Dr-PH on CLZ Books

Keep track of your books!
I have used this app for several years after many other trials that did not work well and I must say I have had the best customer service any time I have a suggestion or find an issue. As a book collector I depend on it to show me my existing collection as well as any library books I may read, when I am out at the bookstore. The new ability to separate into collections is great! I have books in boxes and now I don’t have to view them when looking at my collection list. Keep up the good work! — BookMage on CLZ Books

Fun!
A great and fun way to catalog one's library. I have over 2,000 books and this app will help organize it. — Joe Blavatsky on CLZ Books

CLZ book collector
This is the library app I wish I had discovered years ago ! Once you have mastered the knack of recording your books it is outstanding in its attention to detail. I asked a question of the developer and within hours I received two helpful responses. I particularly value the genre section where you can add your own titled files. The tag section is also valuable for books which are a collection of themes under one heading. Like any good filing system the real test is how easy is it to retrieve what has been stored and this app passes with flying colours. — 19Bookworm on CLZ Books

Love this app
This is the best app to document your library whether it is digital or actual books. I love this app and totally recommend it. It is worth the cost. — Stephanie B on CLZ Books

Multiple Collections!
I am so happy with the newest version of CLZ Books. Now I can finally keep separate lists of my “regular” books versus those in my craft library. It’s very easy to transfer books to a new collection if they’re already in the database, so you don’t have to re-scan anything. The only thing I would tweak is to have the Search function work across collections, rather than just the one you’re currently viewing.
I use this app in conjunction with the Book Collector desktop app, and the collections sync nicely from one to the other. The collections are also easy to view in the CLZ Cloud.
I also use the Music and Movies apps and desktop versions. This collection of software adds value to my day-to-day activities, and is the only software I ever thought worthwhile to pay for a service/renewal plan. — LMB0001 on CLZ Books

Quality
If in Australia I would only use the cloud version. But I particularly like the way the phone apps, the cloud data as well as the laptop data base all sync so easily.
Having had 5 friends in different locations add to the the library over the past few months we would conclude overall that the software is very good. Each individual found their preferred way to add books and search for covers. Any questions we had we were so promptly answered... this gives such confidence in the quality of the software and its future development. When I get to the school in Kenya it will be interesting to to see if the situation is going to be suitable to do all the school borrowing from the laptop library data base. Electricity for charging can be intermittent. We may need a paper system as well. — Max Sargent (Australia) on Book Collector

Best Book Organizer on the Market
I’ve tried two other apps to keep track of my huge book collection and have been disappointed... until now! Finally, someone who gets it! Easy input by scanning the ISBN barcode (for most books), or typing in the title. Contains more information than other apps by linking to the Library of Congress. User friendly in that all data can be manipulated to meet specific requirements. Thumbnails are included and can be changed if needed. Pick lists are editable, too. Try it, you’ll like it! — Consumerpaul on CLZ Books

Great app
This app is pretty great. I only use it to track the books I’ve read not necessarily books I actually own. I found buying books kinda of wasteful so I just borrow books from the library. — mmw604 on CLZ Books

Great package
Great resource for my Library! — Barbara Vincent on CLZ Books

You've nailed it
I absolutely adore your software, and have had a blast adding my nearly 3,000 books to my database. (I've included a pic of one wall of my library.) It's fantastic to be able to check the mobile app while out shopping, to make sure I don't buy a duplicate of something I already own.
I wish you continued success, which you greatly deserve, because you've nailed it with the library software.
I have recommended your apps to many people – anyone who collects books, music or movies – and will continue to do so, although I think I’m too old to know anyone who collects comics or video games. LOL — Melissa Bailey (USA) on Book Collector

Great tools
Me and my organisation enjoy your software a lot. We have an amateur library and your tools are great for that. — DP (Netherlands) on Book Collector

I'm a real 'book-aholic'
My collection of books has grown till more than 8900 books today. For years ago I used a little library program I'd found in internet. It was for free and so it has its restrictions. I don't know no more the year I heard the first time from Collectorz.com. It must be one of the starting years of this excellent program. When I used it the first time, I immediately was devoted to it: now I had the opportunity to find each single book any time in any place!!! From the fast 9000 books I have entered 6450 books in this wonderful program bookcollector: complete with all the data of the books: title, short content, a picture of the front and the back, something about the writer, the edition, the date, the genre, the purchase, the price, the dimensions, the place where to find the books: the kitchen, livingroom, the corridor, the study room, or in my bedroom. And finally I can see the on witch shelf of my big library the book is and or I've lent a book to one of my friends. Since I use this program I can find everything and I never have lost one of my books no more.
A few years after purchasing and using Bookcollector I bought MovieCollector and MusicCollector too and the possibilities to order my collections are endless!!! These three great programs are really indispensable for me! So all my praise goes to Alwin and his team who enabled me to enjoy optimal my collections. — Hub Koken (Netherlands) on Book Collector
