Latest software updates

Today, while flying from Washington DC to Boston, my daughter texted me asking to buy a book for school. Thanks to the Collectorz book app, I was able to tell her that we already own it, where it is located, and text her a copy of the cover. All while flying at several thousand feet. I love this app! — Ellen Edge (USA) on November 28, 2018

Perfect app
I enjoy using the barcode or looking it up by book title or auther. It is so nice all I have to do is use my phone as a scanner, so I don't feel like I'm chained to a computer. Your database organizes the books very nicely. Thank you for making the app. — Sarah Mulvey on CLZ Books

No more duplicates
I've been using the desktop program for years, and the app makes adding books to my collection so much easier. I love the ability to have it when I'm looking at books in stores to make sure I don't duplicate. — John Rogers on CLZ Books

Catalog my books
I am finally able to catalog my books the way I want. The interface took a little poking at to really understand all that can be done with this. I would like a way of cataloging periodicals as well but this does what it says it should do and quite well. — Patrick Carrick on CLZ Books

EASY Restore!
OMG thank you for making it easy to re-download and install AND restore my database from a recent backup!!!! I had the blue screen of death yesterday and had to re-install everything, even Windows10. In a panic, I realized my CLZ book database was gone! But I found it easy to restore by clicking on the backup copy and Voila!
Thank you thank you for making great software! — Bev Connor (USA) on Book Collector

Thanks for all your help
It is Thanksgiving Day here, and while I have a lot to be thankful for in a life that has been richly blessed with friends and family, I must say that I'm extremely thankful to you and the whole crew at CLZ. I'm constantly learning new things in how to use this program and I'm so grateful that no one ever makes me feel stupid or silly (even when that is the case)!
So, thanks for all your help. — Peggy Beatty (USA) on Book Collector
