“First and foremost, many thanks for the app. I find it quite useful, particularly when I'm shopping and am able to verify via my phone/the app if I already have a particular title in my collection!” — Kim Wall

“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

“Ceci est de loin la meilleure application que j'ai trouvée pour indexer ma collection de livres. D'abord elle scanne les codes barre tres rapidement, l'application ne crashe pas (comme d'autres), l'app est rapide et ne ralebtit pas avec le nombre de livres (<1000), meme si toutes entrées ne sont entierement correctes, la plupart le sont. La reactivité est top et le design acceptable.” — Tusca
Excellent, and developing continually

This is a "must have"!

“I work in an old fashioned book store. A customer told me about this app so I had to check it out. There's a computer version & an iPhone/pad version. I'm not near a computer often but always have my iPhone w/me. I was able to add older books. If a picture of the cover doesn't load...I just took a picture w/my phone & edited into the book info. The customer service was wonderful. I didn't realize there was the computer version & a phone version. They refunded me so I could purchase the app. I travel a bit. Now I will never be at a shop w/a book on my hand wondering if I already had it. And if I ever had a fire, I would use this app for insurance purposes. I've already looked up a books in my personal collection for customers at the store. Ahhhh....life is good!” — Hatrick81
A joy to use

“I downloaded a dozen or so book cataloging apps to try them out. Mostly, they went from bad to worse. CLZ Books was superlative: user-friendly, smart, fast, and intuitive. Keep up the good work!” — Sistah Eve
