Latest software updates

I have been so happy with the book collector software, especially since it can be synchronized with information on my iPhone.
It is wonderful to have a portable listing of my book collection. I commend you and your team for development of excellent products.

The Best App for cataloging your books
I’m up to 2454 books without a problem. I especially like the new placement of the sort/select buttons on the main screen. The developers continuously improve their apps in response to the users needs.
Kudos to all. on CLZ Books

Brilliant app
Your app is brilliant, there aren’t any other bookdatabase app that’s better than yours, I’ve tried them all, and none of them come anywhere close to your app. I hope you’ll keep supporting it for many more years to come. And remember, instead of giving up on the app in case of not earning enough to keep it going, if that were to happen, just raise the price or make a subscription price for us to pay every year.
I love your app! — Tine Sandvold on CLZ Books

ALWAYS flawless
I do wish you could teach America software companies how to do software updates. Yours are ALWAYS flawless and so easy to perform. NO ONE has a better update system than you run and I am extremely thankful for it.
Just wanted to let you know I appreciate all that you do and feel you really have a fantastic system working. — James Stephen Lorson (USA) on Book Collector

Love this program
I really do love this program. I used Delicious Library for a number of years but when I moved to a new iMac I had difficulties porting my data base. I stumbled upon your program and have never looked back.
BTW, my wife and I, together with some friends, are going to be visiting Amsterdam next year. I am looking forward to seeing the Vermeer’s. — Joseph Shidle (USA) on Book Collector

Endlich das ideale App gefunden
Seit Bento eingestellt wurde, war ich auf der Suche nach einem adäquaten Nachfolger zur Verwaltung meiner Bibliothek und der Musiksammlung. Jetzt habe ich mehr als nur Ersatz gefunden. Die Features lassen praktisch keine Wünsche offen und der Support ist vorbildlich. — Wop Bop A Loo Bop on CLZ Books

Excellent program
Yours is an excellent program, which I use and have used extensively for both my academic and personal library for many years. I am currently researching the history of "The Poppy" and "The Tulip" in your regional history as part of a personal biography ( I passed many fields of both during a motorcycle-camping tour of the region in 1957 and remember both the flowers and the desolate appearance of Waterloo...beautiful flowers and memories). — Don Speer (USA) on Book Collector

Exceeded my expectations
I have been using Book Collector for a couple of weeks now and I must report that it has exceeded my expectations in form and function. It is a well thought out program that is comprehensive, intuitive and aesthetic. The customization options are awesome. Kudos to you for coming up with such a program. This is exactly what my book collection was screaming for. Thank you. — Christopher R Carey (USA) on Book Collector

Love this app
It does a great job of helping me catalog my books. I love that it stores the database on my phone, lets me sync to the cloud and my iPad so I have multiple backups. I upgraded to pro version of this plus CLZ Movies and Music apps. One of the best apps of any type ever! — Chris Lockwood on CLZ Books
