No more duplicates
Finally have a way to keep track of all my books and no more duplicate buying when out shopping! — Candace Buyuklu 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

Love this app
Excellent way to keep track of the books I’ve read. Easy to add books to the collection, very few I’ve had to add manually so far. And I’ve read some oddball stuff. I had a small problem when I moved from a monthly to yearly plan and support was very responsive; led me through the fix and got me going quickly. I’ve tried others, free and not, and this app is well worth the price. — Miss Eddyp on CLZ Books

Awesome app and support
I downloaded this app after trying many book tracking apps. I found this to be the best interface to help get my son interested in reading. The cover flow is a great way for my son to see what he has read and help him to keep track of his favorite books. I love this app and company. — jwiens35 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

CLZ Books
Having taken the time to evaluate this app I can honestly say it is a great way to keep track of your ebooks. Sure it is laborious entering the details if like myself you have thousands of books but believe me it is worth the effort. I love the fact that I can open the book details and see when I purchased it and when I last read it. The support you get is first class, any problems just email and you get a fast response. Highly recommend this app for all bookworms out there like myself. — Kerig Girl on CLZ Books

Excellent app for keeping track of your books, especially if like me you have bookcases all across the house. Ideal for looking up what you have from which author and if you have that title. — Paul Goodison on CLZ Books

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

Love this program
I do love this program to keep track of my books. I love reading. This has helped me not buy duplicates (partly why I want kindle books added to my list). Been known to buy a book twice because forgot already purchased it. Lol. Now I can look it up on my phone so I don’t do that. — Sara J (USA) on Book Collector

I love this program
I've been using Book Collector for 2 years now and I've finally gotten my ebook inventory completely entered. I know I often contact you with questions, suggestions or bug reports, so I wanted to take the time and let you know how much I love this program. I looked for a long time for a catalog/database program that would let me enter the info I wanted to keep track of. Your software more than fits the bill wonderfully. The fact that I can customize so many fields to match my needs is fantastic. — Brenda Claussen (USA) on Book Collector
