Latest software updates

I've been looking for an easy to use app to catalog my personal library, and CLZ Books is absolutely fantastic! It's better than the classic card catalogs at the libraries. And you won't get hangnails sifting through the cards. I love it so much, I suggested CLZ DVD to my boyfriend and now he uses it to catalog his collection, and my brother uses CLZ Comics for, you guessed it, his collection. — Marita M on May 25, 2021

The best
Best personal library app I've used! With the computer version, reports can be printed for insurance purposes. Excellent program!! — Susan Stenberg on CLZ Books

Home library
I have a home library of around 350 books, and growing. It was getting to the point where I didn't know which books I owned already. I got CLZ as my home library database and have really enjoyed having it. It's super easy to scan books in or type in the ISBN, and it's easy to search as well. So when I'm at the book store I can quickly see if I already have a book or see what books I'm missing from a particular set. Definitely recommend for anyone with a large home library. — Lauren Rose on CLZ Books

Personal library

Large home library
We are very avid readers and have a large home library. This app keeps a complete list our books so when we are in our local bookstore we are able to see if we already have a copy or not. My only complaint is that not every book is listed in the database so I occasionally have have to manually add a book but that is a very minor inconvenience for what this app does. — Gerald Delgy on CLZ Books

Simply the best!
I’m a retired history professor who has a lot of books in my personal library. CLZ Books handles everything brilliantly and makes my research so much easier. Not only that, but if you have a question, or problem, the help is prompt and really helpful. Keep up the good work. — masad92 on CLZ Books

The best book organization and book database app on Android
Scanning is easy and fast. It also retrieves the exact edition of your book so your database is accurate as possible. This is a must-have for those who have hundreds of books in their home library like me. I really appreciate that when the app shifted to a subscription-based app, early adopters like me who paid for the app still receive updates for the app. Thank you so much CLZ team! — Shane Comota on CLZ Books

This app is excellent
It allows me to scan in most of my book collection using the ISBN barcode. A small minority of my collection is not in the database yet, but inputting these is not difficult. Finally, I can download a custom CSV of my library to make a spreadsheet. The app interface is efficient and pleasant to interact with. This is app is an ideal took for a book collector like myself to use to catalog a personal library. — Sean Sovine on CLZ Books

A great app
I bought this up as a surprise for my husband (a voracious reader). I decided to create a digital catalog of our home library and it makes life so much easier. A great app and a great customer support team! — Olga.I.A on CLZ Books

Worth it
Very helpful with keeping track of your home library. I usually don't buy apps but it's been worth it. — Eryn Davis on CLZ Books

Excellent program
Yours is an excellent program, which I use and have used extensively for both my academic and personal library for many years. I am currently researching the history of "The Poppy" and "The Tulip" in your regional history as part of a personal biography ( I passed many fields of both during a motorcycle-camping tour of the region in 1957 and remember both the flowers and the desolate appearance of Waterloo...beautiful flowers and memories). — Don Speer (USA) on Book Collector

The perfect solution
Book Collector is the perfect solution for anyone who loves books. It’s extensive functions allow tracking of anything and everything about a book and how it is used, but not daunting if its only purpose is to manage a home library. The website is easy to use and the online manual is well-organized and clearly written.

As a blind computer user with Apple’s screen reader, I am always so grateful to find such a high degree of accessibility in a program like this. It is a blessing to be able to manage my home library without the need for much sighted help.

It is a credit to your programmers that the program is accessible. They obviously took care to meet the guidelines for its support. I suppose that not many blind folks care about books. My blindness came on in my 30s so I had a house full of treasures I wanted to recall, organize and pass along to my son. Audio books have kept me sane but there is nothing like a book in hand and turning a page. I fear before too long too few will be able to know that pleasure.

I have enjoyed working with you. Your communication skills are outstanding. I hope that whoever pays you recognizes the value in that .

If you are ever in the USA and near North Carolina, Do let me know. I would like to thank you in person and buy you dinner for all this effort on my behalf. Truly. — Leslie Stephens (USA) on Book Collector

This is a great APP!
Easy to use. Great for cataloging your personal library. — Starguardian2000 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

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! — Joy Masler (USA) on Book Collector

Delightful program
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. — Debra Ice (USA) on Book Collector

Excellent app
I have been using CLZ Books for 3 years now (on my desktop and more recently on my iPad and iPhone), and it is outstanding for keeping track of my personal library, history of purchases and reading log, and my ratings as well. Totally recommend. — Gaucho_97 on CLZ Books

Great tool
Although I haven't yet had time to fully explore all of the features of the software, I have been greatly impressed with the features that I am already using, and overall I find the software very user-friendly and a great tool for managing a personal library.

It's the sort of thing I dreamed of having 20 years ago when I first started building my collection, and I have recommended it to several friends with large collections like my own.
The fact that you have people available to offer such excellent customer support makes me all the more impressed with your company — Kelly M. Fiske (USA) on Book Collector

Love Book Collector so much
Hi Collectorz!
I would like to share The Yellow Library which is my home library that my husband and I designed (DIY). :)
I want to inspire booklovers everywhere to dedicate a special room for their books!
My book blog is named after it :). I love Book Collector so much that ive been recommending it to all my booklover friends and blogged about it — Aimee Lorraine Keh-Lee (USA) on Book Collector

I'm in heaven!
I have been using Bookcollector on my PC for years and am VERY satisfied with both how user friendly it is and how customizable it is. Plus it just keeps gettting better and better!
At first the little app for my iPhone seemed rudimentary (unless I was missing something?) but now it has all the details and the App for my new iPad 3 with retina display and the cover images just blows me away!
I LOVE my personal library of over 3,500 books and now if I am talking to someone about a book I have that they might like I can just whip out my iPhone or IPad and show it to them. What fun! Bookcollector Helps me actually find and use my books. — CreativeCompass on CLZ Books

The best
I like the hard work you guys put in to build the best book collector's organizing set of tools that will enable me to do just that with all my books. I purchased all the tools but have yet to get it entirely functional because I have too many other things going on right now too. But with a little more time I will be set up.
I am anxious to discover just how large my personal collection is (my guess is about 2,000 books), to have it organized, an to enjoy the full functionality of it all. I will be happy to share before and after photos of my current mess versus my organized structure that is one of my primary projects now, including a new custom build home library with floor to ceiling bookcases in my office.
Thanks to all you folks in Amsterdam, Steve from Oklahoma City — Steve Copeland (USA) on Book Collector

Great App!
For book lovers like myself, this is a great app for those that did buy as well their PC/ Mac software, which by the way is awsome ( they make it clear that this app does not work on a standalone basis, you have to have their software on your computer).
Perfect catalog for your personal library. — Gaucho_97 on CLZ Books
