Love this app
Needed an app to inventory my books for insurances purposes. Looked around and this one seemed easy to use. Was well worth purchasing, use it almost daily and so easy to use. Love that you can put comments, etc! — angeliquedes on CLZ Books

Works like a charm
4500 books and growing my inventory. Works like a charm, easy to use. Almost 2 years later, still very satisfied with Book Collector. Now managing over 25,000 books via using both desktop and Android versions. Work well together, application is updated regularly.
Support is great, have issues? They will respond pretty quickly and help you with the problem. Staff responds well to suggestions and questions and have helped me quite often. — A Google user on CLZ Books

CLZ Books
I purchased my CLZ Book Collector mid-2005 to inventory my late husbands book collection which is now over 4000 and counting. First, I have to compliment the CLZ support team for their immediate and helpful response over these years to any inquiries, technical or otherwise. I recently purchased the CLZ Book app. I look forward to utilizing as going through my collection on the app I can maneuver easily, access any title, author, and readily add to the collection. The app provides convenience and flexibility away from the laptop. Props to the CLZ team who continually work to improve their product for the benefit of their customers. Cheers!

I love this program
I've been using Book Collector for 2 years now and I've finally gotten my ebook inventory completely entered. I know I often contact you with questions, suggestions or bug reports, so I wanted to take the time and let you know how much I love this program. I looked for a long time for a catalog/database program that would let me enter the info I wanted to keep track of. Your software more than fits the bill wonderfully. The fact that I can customize so many fields to match my needs is fantastic. — Brenda Claussen (USA) on Book Collector

So far so good
I've been looking for something I could inventory my collection for awhile now. This is the first I've found that allows me to scan via ISBN and manage my collection via app or PC. — Darrel Spurlock on CLZ Books

This program is unbelievable! I've had my own version in Microsoft Access for years and with the purchase of an IPhone I wanted to get the inventory on the IPhone; In no time at all I was able to import over 8,000 books. I've transferred to them to my IPhone also very quickly. The barcode scanning technique works perfectly with a $9,99 scanner.
Thrilled to have found it! — Richard Dayton (USA) on Book Collector

Full inventory
I have been using book collector for many years but have just really gotten serious about doing a full inventory. During this time of making a much more extensive use of this program let me first say I love it!!
Thank you for your fine product, I am really very very satisfied with what it does. — Luke Burgess (USA) on Book Collector

One great data base/software
This is one great data base/software.
I have scanned and categorized 230 + books in a very short time. The next phase - adding books with no bar codes will take longer, but I am confident that it will go well.
The very old books I will leave for the third and final inventory.
What a lot of thoughtful work you have put into this program. Thank you! :) — Judy Baldridge (USA) on Book Collector

Anxious to scan the books
I just downloaded the book inventory system and the scanner. I got one of my books and scanned it! Up comes the book cover picture, a description, ISBN number. WOW!

The kids are going to help me scan books intomorrow on the last day of school! WOW! This is so reasonable in price and will be so much fun. I think the kids can even scan books for check out (I have to keep reading my instructions, LOL!).

THANK YOU! I now have a way to organize my classroom books (close to 3,000 maybe?). My students are helping me clean my room and are anxious to help scan the books in! I posted on teachers.net about your product so others can have this system! — Deb Burton (USA) on Book Collector

A time saver
Thank you for putting together an inventory program for my book collection. It has been a blessing to use.

A breeze
Book Collectorz is so fantastic!

I've used it to create a library for our school. It acts as our card catalogue and it is wonderful! Its super easy for teachers to use, making finding books by subject a breeze. Its also easy to manage "checked out" books through its Loan feature. Its been quick and easy to add new books automatically or manually, and makes taking inventory a breeze.

I love that I can tag books by their topics to create easy reference themed lists for display; Poetry, Valentines Day, Feelings, ABCs, . . . . I am by no means a computer whiz, knowing only the "basics" on my Mac, but this program was easy to learn, modify for our needs, and teach to others. Their manual and online support are thorough, quick, and strait forward enough for even me to follow.

The school administration has been so impressed with how organized and slick looking this program is. It really makes me look like I'm doing way more than I actually am : )

I love, Love, LOVE it!Now I can't wait to organize all of my books at home!

5,000 books
I am currently using Book Collector 4.8 and so far it is winning hands down over the other book inventory software that I have been evaluating. I currently have approximately 5,000 books in my personal library. — Karla Marciszewski on Book Collector
