Latest software updates

I absolutely adore your software, and have had a blast adding my nearly 3,000 books to my database. (I've included a pic of one wall of my library.) It's fantastic to be able to check the mobile app while out shopping, to make sure I don't buy a duplicate of something I already own.
I wish you continued success, which you greatly deserve, because you've nailed it with the library software.
I have recommended your apps to many people – anyone who collects books, music or movies – and will continue to do so, although I think I’m too old to know anyone who collects comics or video games. LOL

A breeze
You guys are impressive in how you keep the product maintained. I use it a lot in my writing. I use the software multiple times a day (some days) to do key word searches for 'color' detail information about an historical topic I am writing about. I am very careful about setting up keywords etc when I enter a book so looking up information is a breeze. — Bob Bernhart (USA) on Book Collector

Great app for the bibliophile
It's really easy to use for the most part. There are a couple small features I am not particularly fond of, but I know one is being worked on as of now. They're always improving the app and the software versions so I have faith that in time there will be even more improvements and options. syncing between versions is super simple too. And the money I save at the bookstore by not purchasing duplicates makes the app more than worth the cost. — Angi Clingan on CLZ Books

The best!
The best app of its kind! Only reason for not giving 5* is because would love the option to have 'start' and 'finished' reading dates, rather than just the 'reading date' available. — Sabina Vazquez-Rey on CLZ Books

Awesome
Awesome app! — Les Phillips on CLZ Books

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

Multiple database support
This feature certainly multiplies the value of Book Connect. You guys amaze me.
Just in the short period I have been with you, Book Connect has mushroomed in utile. — Donald Conner (USA) on Book Collector

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
