CLZ Books reviews from customers
Edit: one other thing to note: I actually appreciate that this app is supported by a very reasonable subscription fee. The last thing I want is an app that is free and never updated and eventually dies, or a bunch of ads. If you do eventually tire of paying a small fee, you can easily export your library.
As I passed 5000 books, I came across a review of Book Collector software and purchased this along with Movie Collector, which I still use also. The program was fantastic and Alvin and his company have evolved the product continually. It is easy to adapt, change and modify. I have hundreds of art portfolios, prints and some original paintings by SF and Fantasy artists. I have incorporated these into my catalog with photos of the prints. I also have 1500 SF magazines from 1920’s to present that I may incorporate as well, to join my 6500 books. I can now find anything I want in seconds. Many have assigned values if signed and collectible.
This was all made possible by the constant attention of the company to function. Hats off to CLZ!
