Latest software updates

Just a note to wish you well during these difficult times. I have just updated my subscription plan though to 2023. It made me stop and think that will probably be more than 20 years that I will have been using the software. It is difficult to cast your mind back to remember what the screens used to look like and the limited functionality. Well done to you all for developing a fantastic product and sticking to it through good times and bad.

Want A Library App? THIS IS THE ONE
Just purchased this app along with Book Connect. Excellent package. Works flawlessly. And did I mention the (pre-sale) support. OUTSTANDING. Why can't every app interaction work this well? HIGHLY RECOMMENDED. — Ken Philip on CLZ Books

Bien fait et très utile
De même que CLZ Music, CLZ Books est bien ficelé. C’est certes un peu cher, mais depuis que j’y ai entré tous mes bouquins, mes vinyles et mes CD, je n’ai plus jamais acheté quoi que ce soit en double. Ça justifie déjà le prix. Et Alwin assure une assistance rapide et efficace en toutes circonstances. Bravo ! — jobarfou on CLZ Books

Great library experience
More than 15 people who are on our Library Committee and staff have looked at our 1500 book catalog in CLZ Cloud and are very pleased with it. To a person, they have said how user friendly they think it is. I am delighted since there were several people who questioned why we needed a catalog. You know how some older people are about change! I am an older person too but I am thrilled to offer your product as a great improvement to our library experience. Just think, we can check for books in our retirement community's library from the comfort of our own apartments and cottages! — Betty Iwan (USA) on Book Collector

Outstanding
I have been using the desktop version for years, just recently the app. The most trouble free programs you will find. On top of that, if there ever is a problem, their customer service is the best I’ve dealt with. Customer service response is fast and best of all, knowledgeable. For the minor issues I’ve contacted them about, all have been resolved promptly and without issue. — jmfs15001 on CLZ Books

Can’t believe how well this works
I have a collection of train books (100+) that I have needed to catalog for years. I was dreading using something like Excel to do this. Not real proficient with this software yet, but it is amazing the authors and titles that pop up. Train books are a real subset of literature, but you guys seem to have a lot of it covered.
Completed 2 shelves of books in about 20 minutes while learning how to use the program. Now I have documentation if I need it for insurance. — C on CLZ Books

Thank you!
Hey everyone at CLZ, just wanted to say thank you for making ‘Extras’ from the desktop edition a part of the web edition. This is where I was keeping info like if it was signed. I would get a list of books from a bookseller and some of them would be sighned. I knew I already had some of the books but I couldn’t remember if they were signed. I would have to wait until I was home to see if my book was signed or not. Now I can see this info from anywhere! Thank you! — Sherri Reid (USA) on Book Collector

Invaluable app
Would not be without it. Invaluable when choosing books in library. — Stuart Ogg on CLZ Books
