Latest software updates

Alwin and Team,
I've been using Book Collector for a number of years now and decided it was about time that I express my appreciation to you for not only developing the best "book software" product on the market, but also, for your continuing updates and frequent communications. Book Collector has more than met my needs for the 2,000+ books I've logged. So again, a well-deserved thank you to you and your staff.
P.S. I just recently purchased Movie Collector to log all of my DVDs and CDs. I'm very satisfied.

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

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

This isn't a question just a "well done". The clarity on the new screen text/images is fantastic. It has given the application such a clear and modern look. Brilliant.
