Great app for your CD collection

Amazing how fast you can add music into database from old 78s to barcodes. Back in the day if your album had 17 tracks you would be typing in every track and hope that an album cover picture was available online to import.
All I can say is WOW.

Honestly, I love it

Between my phone and the web it's so easy to catalog my...very many books and get them straightened out. I may also do it (web+app) for my comics, but that's less of a pressing issue at the moment as the app works perfectly for me right now.

Wish I had found this app sooner

Has really helped me organize my library and keep me from duplicating volumes. Found it easy to add books to the collection.

Amazingly easy to use

I love that i can scan from my computer or my phone and sync then together so I always have a list of my books where ever I go.

Easy to use

A great comprehensive but easy to use database.

Looks good and works brilliantly!

Just add books by isbn works great and if a book hasn't been added you can do that yourself and that's pretty easy too. What I especially like is there are two different coverviews. The only thing that could make it better, for me, is if you could rate the book at the same place where you mark it as being read.

I can't ask for a better book app

CLZ Books has been exactly what we needed to catalog all of our many books. I first got it to replace the multi page list of books I had and was looking for that I would carry into every used book store so that I would stop picking up duplicates unintentionally. The ability to quickly add most books by scan and sort them into collections is helping us get a better grasp of the rooms of books we have. Customer service if ever needed is quick and helpful.

Amazing app

Great tool to use to manage your book collection. I also use their Comic Book app to manage all of my collection. Fantastic company. 10/10!!!

The app has been phenomenal

I have an extensive, very large collection of children’s books that I have been hoping to catalogue for some time, and the app has been instrumental in helping me do this. I have been able to catalog 800 books and counting so far, and have also been able to use the “edit” function to add details.
I am an early childhood special educator and it is my hope to be able to add more details to each of the books I have logged in order to sort them by subject/theme to support how I utilize my library in the classroom (I am currently just logging my home book collection, and have yet to tackle those books that I have at school).
All in all I am so grateful for the app - it is just what I needed and has made cataloguing the books a breeze!!

Indispensable

I recently purchased the CLZ Book app and it’s fast becoming another CLZ favorite (I’ve used the Music and Movie apps for many, many years). Hundreds of books are now in a manageable data base with no more physically searching shelves and stacks to see what I have, making it easy to check that I’m not purchasing another copy of a title.

Beste

Ich liebe einfach alles an dieser App. Wenn man seine Bücher sortiert in einer App haben möchte und keine Social Media artigen Community Funktionen braucht, dann hat man hier alle Möglichkeiten und Freiheiten.
