Always have my list with me
I have this software for my 800+ books. A great way to always have my list with me, to prevent the occasional "double purchase" of a book. I recommend to you for your library. — Thomas L Hiegel (USA) on Book Collector

Thanks For Adding AutoCorrect Options In The New Update
This app just gets better and better. Thanks so much for adding the new auto correct options that were added in the latest update. This is a game changer for me because I keep so many book notes. Now it is so much faster to type notes and to add more plot summaries and etc. to my entries. Hopefully you will add this update to other CLZ apps such as comic CLZ and Movie CLZ because I keep many notes in those programs too.
I highly recommend this app to anyone who is a big collector. It is probably the best out there. It's definitely the best one that I have seen so far and I've tried a few. The staff in customer support is also very friendly and always working to improve services. — RonP1979 on CLZ Books

Been using it for 4 years and is lovely
Like some people here I had problems with the 100 limit. Please do a little work before you start putting down this app. I went to the developer website and email them. Because of the many changes things like connectivities to my App has gone a bit south. You don't have to buy it again!! Just email them and they will take care of you. I had to do a screen shot of my purchase and send it to them. My APP was working within minutes. I bought my APP 4 years ago and I had never have to buy it again. They will help you. Try them. : ) — Makora One on CLZ Books
