Latest software updates

This is an excellent app! It makes physically organizing your collection on shelves a breeze. Plus, no longer will you have to get up and search through your collection to find if you have a title by a certain author. You can scan your collection in a matter of seconds in order to find out.
Since I have it on my phone as well as my iPads, I can use it in the bookstore, too. No more buying an older title only to find out I had purchased it years before. Support is excellent as well. I have the CLZ Movies app, too. I love them both!

The perfect solution
Book Collector is the perfect solution for anyone who loves books. It’s extensive functions allow tracking of anything and everything about a book and how it is used, but not daunting if its only purpose is to manage a home library. The website is easy to use and the online manual is well-organized and clearly written.

As a blind computer user with Apple’s screen reader, I am always so grateful to find such a high degree of accessibility in a program like this. It is a blessing to be able to manage my home library without the need for much sighted help.

It is a credit to your programmers that the program is accessible. They obviously took care to meet the guidelines for its support. I suppose that not many blind folks care about books. My blindness came on in my 30s so I had a house full of treasures I wanted to recall, organize and pass along to my son. Audio books have kept me sane but there is nothing like a book in hand and turning a page. I fear before too long too few will be able to know that pleasure.

I have enjoyed working with you. Your communication skills are outstanding. I hope that whoever pays you recognizes the value in that .

If you are ever in the USA and near North Carolina, Do let me know. I would like to thank you in person and buy you dinner for all this effort on my behalf. Truly. — Leslie Stephens (USA) on Book Collector

The best and by far
I’ve tried many apps to catalog my books and Collectorz.com is the best, and by far. Specially for someone like me who has a large collection and a large wish list. The same apply for their movie app. It’s really great. — Daniel D on CLZ Books
