Latest software updates

I have 24 bookcases with six or more shelves full of books to be catalogued and sorted. I am doing this so my girls will be able to decide what to keep or discard.

Life savers
Have both Books and Comics apps, and they are both life savers for the amount of books I have. There will be no more buying a book I already had. — steve jones on CLZ Books

Powerful app
I have used this app for quite some time and it just gets better with ever update. It's a powerful but simple way to do all the cataloguing of my many books and games. I recommend this to anyone who wants to catalogue. Many useful features and at a good monthly subscription rate. — Keith Michael Spence on CLZ Books

Great application
After a long search for archiving books and music, I finally found the application according to my ideas. It is absolutely fantastic, modern. I definitely recommend anyone looking for this type of application not to save money and buy this app. You will definitely not find a better one. Now I have it on my iPad, but I'll probably buy it on my PC so I can add books and music over my PC. Even if more covers could be added. — vladino sk on CLZ Books

Pretty good app
My only gripe is that in some books with multiple authors, I do not have control of the order the authors are listed. Otherwise, a pretty good app.
Update (31/08/2020): The version released today solved my problem. — Jun Fuerte on CLZ Books

Finally organized my book collection
This is a great app and has helped me to finally organize my book collection. Their customer service is also excellent. I had a small problem, which was down to the setting of my app. I emailed them and they were very quick to respond and resolve the issue for me. — Andrew Craig on CLZ Books

Easy to use

Useful system
I would like to say how very useful the Book Connect system has proved. The original purpose of cataloguing this collection – 7,800 items – was to enable it’s eventual distribution among a large number of beneficiaries; charities, museums, family and friends. Having the collection available online, in a non-editable format, has enabled many of these beneficiaries to submit relevant wish lists.
Your help/back-up service is exceptionally good! — Richard Campbell-Howes (United Kingdom) on Book Collector

Awesome
I love this app. It is so easy to use. But most of all I am very pleased with their customer support. I had a bit of a problem getting set up, ( no fault if CLZ) and they worked with me until everything was set up. Their service was prompt, courteous and helpful. My son and I also have their comic book app and it's great. I would recommend this app to anyone. — jackie becker on CLZ Books
