Latest software updates

I have used CLZ software for several years, for my audiobooks, and hard and soft covered books. Also, I use their software for all of my movies, whether it be DVDs, Blue Ray disks, or what I've bought on Amazon Prime Video. Of all the many software/apps I use CLZ programs are among my favorites. The book and movie programs are what I use to inventory my stuff. — Richard Menard (USA) on July 09, 2023

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.

Thanks again for a marvelous app
Thank You for reaching out! I sincerely appreciate that extra bit of customer support and actually cannot say enough good things about this app! Lol I have been telling all my friends about it! I even shared it to my pangobooks page and have an upcoming post on my instagram about this app! I uploaded over 500 books in one day! And over 100 more since then! I have numerous copies of each title and this app made it a DREAM come true for keeping track of all my books!
Thank you from the bottom of my book bogged heart!! I wish my P.O.S. inventory was that easy. I love that I can keep track of books that I have, that I don't have but wish I did, and books I have extras of and sell those but they stay in my catalog if it's a favorite... lol. I will definitely save it to the cloud then I didn't know what that function meant yet so thank you. — Reader Jo on CLZ Books

The best one
For a book organizing app, this is the best one I have found so far. Its ease of entry is well done, and getting your collection or inventory in this app is quick. This app deserves 5 stars for its function, and another 5 for its support. My initial review asserted a critical error against the app, when in fact it was mine own ignorance. These folks care about your experience, your privacy, and the app. — Spencer Burton on CLZ Books

CLZ Books - Book Inventory
I have owned CLZ books for nearly ten years and could not be happier with it. It is worth every penny. The most convenient feature of the app is the bar code scanner. You can add books to your inventory or see if you already own a particular book. — proculus1 on CLZ Books

Great Book inventory product
I own over 540+ books and this does a nice database job. I buy a lot of HISTORY books and computer books, this works great to prevent duplicate purchases. When looking at new wish books like the wish list for recall when asked for gift ideas. Like the detail and the book cover pic to compare if purchase or already own. Easily search when shopping especially mobile. Alwin & Team constantly adding new features Via enhancement updates. If there is a problem The Team addresses it very quickly although i have owned for many years and haven’t found too many issues mostly just added enhancements. Highly recommend, cost effective and enjoy it so much purchased several other of his inventory products. Couldn’t add to collections without this product And adding via Title or even better ISBN code is great. App is flexible and allows for cover graphics override so can match exact ownership version. Highly enjoy & Recommend. — Barmeister 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

Unbelievable
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 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
