Fantastic app
Fantastic app that helps me keep track of all my books in an orderly way. I find it most useful when shopping - a quick glance and i can see whether i, or a family member, already has a book! — A Google user on CLZ Books

Wonderful App
This is a great app. I’ve used it for several years to keep track of books I’ve read. Since I’ve read over 900 books it’s important to me to be able to see which books I’ve already read. I’ve had absolutely no problem with this app. My list syncs perfectly between my iPad and android phone allowing me to review my books on either device. — GrandPuppy4 on CLZ Books

Makes the lending of books a breeze
As Library Coordinator for our chapter of a national environmental organization I use Book Collector to stay organized. The software makes the lending of books a breeze. We have over 230 books which some of your respondents would scoff at but, since I haul the books to monthly meetings, it is plenty big enough.
I value Book Collector highly and rely on it to keep track of all details of running a much used chapter library. Thank you and keep up the good work! — Virginia Watson (USA) on Book Collector

Handy when I'm book shopping
I use it to keep track of what books I have, so that when I shop I know if an interesting book would be a new addition to my library. I find it easy to add books by scanning ISBN bar code on back cover or inside cover, which works for almost all books. Older books (~40+ yrs) that don't have recognizable ISBN, I search by author and title then select to add (still relatively easy). In very rare cases I've added a book manually and included the front cover picture that I took myself. — C101481 on CLZ Books

Fantastic!
I love this application. Whether you have a book collection you want to want to catalog or just want to keep track of what you have read you can't beat it. Just scan the ISBN number and the app pulls in a ton on info on the book. You can create folders if you choose. Extremely useful. — Wilfred the Barbarian on CLZ Books
