I’ve been using this app for over a decade, and it keeps me from purchasing duplicates. Not only do I enjoy the book database capability, but I particularly appreciate the customer support. The two times I have needed help, I have received a response within 24 hours. They also update the app on a regular basis, so they are always working to offer an improved product. This is a great app for book collectors.

Excellent
Excellent app for creating and maintaining your book collection. I've been using their comic book database manager for years and decided it was time to oversee my massive book collection as well.

Amazing Team at CLZ
CLZ Books is a phenomenal app. By far the best book database app out there. The user interface is exceptional, but the best part is the team behind CLZ. They are continually making improvements and they always pay attention to customer feedback which is a rare quality for mobile app. In today’s ever advancing digital world, it is essential to have such a responsive team like the CLZ team.

Valuable tool
I have really enjoyed using Collectors Books database. When I am out shopping I am able to see whether I have a particular book. An extremely valuable tool.

The best
The best 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.

EASY Restore!
OMG thank you for making it easy to re-download and install AND restore my database from a recent backup!!!! I had the blue screen of death yesterday and had to re-install everything, even Windows10. In a panic, I realized my CLZ book database was gone! But I found it easy to restore by clicking on the backup copy and Voila!
Thank you thank you for making great software!

High value for our money
I love your apps/software, and i think that we (your customers) get a very high value for our money. Its incredible how much we get for very little money. I hope you never stop supporting your apps/software, because i want to use it for the rest of my life. Im soon going to learn my mother how to buy and use it for her books.
I have tried A LOT of book database apps/software and none of them come anywhere near your products. Thank you so much for your exceptional work:-)

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!!

Best book database app ever! I use it all the time, wherever I go. I always have an up-to-date list of my books and my wish list!

This software is amazing
I was looking for some software that would help me to take my library and get it under control. A fellow Pastor told me that he used Book Collector on his PC and thought it amazing.
I purchased a copy on that recommendation and started to use it. I have to admit that at first it was confusing and a bit overwhelming and the instructions were not the best.
BUT, this product is fantastic. It does everything I wanted. It takes the ISBN number and looks up the book in the CLZ Book Database, it then downloads copy of the cover and all of the pertinent information as well as a summary of the book to your database.
You then input your library information as well as your own notes, annotations, plots, characters, key words, etc. It also asks you for the information of your purchase date, price, where you bought it, etc.
I also allows you to choose categories (and add your own) so that future searches can be done quickly and easily.
It also has a lending tool. You can loan a book to someone and mark that book as "lent out" and it will track the date you loaned it, to whom, where it is and if you want, remind you to seek the return of it after a period of time. Now I won't wonder what I did with a book.
It also allows you to track in your own library where you have the book, in other words, at home, in the office, at school, etc. So, if you take it elsewhere you can mark that and when you look for the book you at least know where you last took it.
BUT THE BEST FEATURE is the scanner tool that you can download for your iPhone or iPod touch. The CLZ Buddy scanner turns your iPhone into a scanner that will pick up the ISBN bar code off your books and automatically fill it into the add feature of the software on your computer. It will allow you to add multiple ISBN's to the que before you search the database. Then you touch "search" and it finds all the info and displays it. You then touch "Add" and all the books are added to your software. It is amazingly simple.
Finally, if you want you can get the mobile app for your iPad or iPhone or iPod touch and download your library database from your computer (via WiFi) to your other device. So, if you are at a meeting and want to reference one of your books, just look it up. If someone asks if you have a book, check whether you do. Or if you are out at Barnes and Noble and see a book but can't remember (happens to all of us) if you already own it, just pull out your iPhone or iPad and check to see if you already own it. No more double purchases.
Well, enough said. This software is amazing. I don't know how I ever got along without it.
Enjoy! It is worth the price.

I simply *HAD* to buy it
I was simply Googling for a book database and found your link. The main feature that hooked my into trying your product was the book cover scans. Very nice!
After I used the wizard to enter some of my collection, I was SOOO impressed at the ease of use that I simply *HAD* to buy it.
I'm a network engineer and I've never been as impressed with a program as I have with your product. I mean, I paid for it after about 1 hours use. Thanks so much!!
