Latest software updates

What can I say? I love my Book Collector. I've so many ebooks and physical books its overwhelming. Before I bought your software, I had double and sometimes triple copies of books I'd already purchased and now, with your software I can stay on target with my books and copies are of the past. I have no funny anecdotes to share but I am very happy with my Book Collector and thankful that you had the foresight to create such an awesome program to make not just mine but other people's collections, be it books, music, games, movies.... such an easy way to keep us organised that we no longer have headaches trying to find what we want to read, watch, listen to or play.
I also am very happy with the prompt responses to any questions I may have. I have you as a friend on Facebook and have not hesitated in asking questions. Your responses have been precise and fast. I like that. It shows you listen to the consumer and do your best to give us what need. Thank you for that.
I also love the app that works wonders when I'm in the bookstore. I can check my collection and add my purchase or just add to the wish list with the bar-code. That is just another part of your Collectorz software that I am happy to have in my devices.
The price for your software is a bonus, it's reasonable and affordable, which keeps me coming back to update. So, again I thank you and although I've done it many times now, I will keep recommending your software to all those I know need it for their own collections.

My books organised
Great app in getting me and my books organised. I love that it could sync with the database that I have online and on my laptops. — Khatina Nawawi on CLZ Books

Absolutely amazing app!
It is so useful when it comes to shopping, since I own a lot of books. It's easy to use, but is organized well. I hope to unlock the whole database soon when I get the moneu to unlock it- I know I have more than 100 books! It'll be worth the investment for such a time-saver. — Eddie Wright on CLZ Books

Makes the lending of books a breeze
As Library Coordinator for our chapter of a national environmental organization I use Book Collector to stay organized. The software makes the lending of books a breeze. We have over 230 books which some of your respondents would scoff at but, since I haul the books to monthly meetings, it is plenty big enough.
I value Book Collector highly and rely on it to keep track of all details of running a much used chapter library. Thank you and keep up the good work! — Virginia Watson (USA) on Book Collector

Easy to use
Finally there's a quick and easy way for me to catalog all of my books. It's so easy to use. My books are organized and easy to access. So now when I go to bookstore, there's no chance of buying repeats. I really needed this. — Tanya Perry on CLZ Books

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

Well worth the money!
This is an excellent app! It makes physically organizing your book 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! — Zircon_215 on CLZ Books

Amazingly easy
After spending all weekend shelving & organizing my hardcover & softcover fiction, Spanish books, & poetry a Facebook friend recommended I check out this app. WOW! It will allow me to catalog my thousands of books. Once it is set up it's as easy as scanning the bar code & tapping a couple buttons. Then it sinks with site in the cloud. LOVE IT! — booksbooks on CLZ Books

Using it for my classroom

Delightful program
Thank you for your speedy responses with answers to my questions. As you explained, my scanner works fine with your software and is making logging my books seem almost magical. My daughter introduced me to your software a couple years ago, but I was slow in getting started – shame on me!
One reason your software is such a gift to me is that about 11 years ago while logging information on about 1500 books on index cards and on my computer, a flood hit our area and our home was affected. I lost about 700 books to the flood and never went back to update my personal library. Since that loss, I’ve purchased many more books to add to those remaining – and inadvertently bought some of them more than once, hence my need for better organization of my books – and with your software I’m quickly updating my records.
Within a short period of time I used my scanner to log nearly 400 books and have asked my granddaughter to come and help me with the rest of the project in a few weeks after she graduates from high school and before she heads off to college. We look forward to working on this project together. What a treat it is to watch those books jump onto the screen with all pertinent information, just by using a scanner and making a few clicks on my keyboard to save what popped up.
I was pleasantly surprised when seeing more book and author details than I was aware of, too – including links for information on Wiki... The list is great and has such a great user-friendly sorter by title or author. When browsing around and clicking on the Images tab and seeing the books lined up on book shelves, I actually leaned back and laughed with surprising joy. Clicking on the Cards tab showed me the little cards complete with each book’s information, and I was amazed.
I’ll highly recommend your software to others and want to thank you so much for this delightful program. — Debra Ice (USA) on Book Collector

Great App
Love books then love this app. Puts all of your books, by author, genre etc and when ever you need to know what you already own browse the app. I love it because I still need to read the books I have bought and it helps me to stay on track. My books are now organised and I immediately know how many by what author. Now I just need to find a quiet place and finally read all the books in my collection. Oh, and there is a wish list for the other books you must buy. Give it a look....it's so worth it. — iamkay14 on CLZ Books

It works properly
I originally bought the Mac program, sort of as a joke because Martha Stewart endorsed it. She is "Miss Organization" and it worked better than I imagined. Both have improved and this version has helped me avoid buying many duplicate books. — Ccwnj on CLZ Books

No more duplicates
My husband gave me book collector as a Christmas gift to catalog my collection of 4,500 books. When I went to book sales, I sometimes purchased duplicates of books I already owned. With the export function of Book Collector, I put a list of my books on my cellphone and now check the list before I buy another book. In addition to organizing my book collection, your product has saved me from wasting money on duplicates.
Thank you very much for your help. Your directions were clear and easy to follow. Book Collector is now correctly installed on my new computer. I appreciate your expert assistance. — Susan Godlewski (USA) on Book Collector

Love the program
For such a great program and for all the professionalism you constantly show. I love the program and I love the way you run your company. So this note is to say thank you for all you do from a home user who loves books and loves keeping the books organized! — Dawn (Canada) on Book Collector

Important organizing factor
Your product is sufficiently flexible that I was able to set up one database for professional journal articles and the other for books. I am a college professor, and your software has become an important organizing factor in my research. — Kenneth Curry (USA) on Book Collector

CLZ Books
The mobile app accesory to Collectorz excellent book organizing database system. Tracks your Ebooks, too. Collectorz offers a complete suite of custom databases to help you organize your life. They are constantly improving their product and offer customer service and support that many other companies can only dream of. You may be able to find cheaper or even free aps that claim to do much of what Collectorz offers, but you won't find better value anywhere. — Brian J Munro on CLZ Books

Wonderful product
You have an absolutely wonderful product - with the book collector program we can loan out (and track) hundreds of books to our clients on a monthly basis, and give them access to resources they would otherwise not be able to use - and it's done affordably, which as a non-profit organization is a huge consideration. without this program, we'd still be using pen and paper - and losing a lot of our resources as well, because they are much harder to keep track of that way! — Becky Irvine (Canada) on Book Collector

Completed my library
So happy to have "completed" my library after many many months of work! Count: 3655!!! Now I can FIND things, and all my books are so much better organized. I'm just cleaning up now, trying to complete records and add editors and translators to the proper field, if I can figure that out! Just now playing with how to sort the columns so I can have a printed copy of the essentials by location. Thank you for helping me with what felt like an overwhelming project! — Ann Hearn Tobolowsky (USA) on Book Collector

A dream come true
Sending greetings and gratitude to you from the beautiful San Francisco Bay Area. Your creation is a dream come true for me! I have thousands of books to get cataloged and organized. I have been wanting to do this for years and you have made it so simple for me.
Thanks again for this incredible product! I hope this turns out to be as great as I think it is so I can create my dream library. — Karen Lipscomb (USA) on Book Collector

Good Book Indexing App!
Over the past several days, I've been using this app to index my book collection. The barcode scanner works great! One helpful hint, especially for paperbacks more than a few years old: use the barcode inside the front cover, not on the back of the book, as that's the one you can count on for containing the ISBN.

If you want to do more than just upload your books, i.e. organize your books by genre, subject, or tag, it can be a bit tedious, as each book must be edited individually. However, if you just want to scan in your book collection and are happy with organization by author and the existing genre and subject labels that come with each electronic book record, you will be good to go.

I've not tried other book indexing apps, so I can't say how this might stack up against the competition. However, I like the simple interface. It's also nice to be able to organize and view my book collection in so many different ways.
Being able to flip through horizontally is the closest I've found to something online that simulates scanning my eyes along a shelf of books. This is a terrific feature! — Theresaawilson on CLZ Books

The very best!
There is no better program out there anywhere that can organize my thousands of books better than Collectorz Books...
Hands down, the very best! — Thomas Taylor (USA) on Book Collector

The best
I like the hard work you guys put in to build the best book collector's organizing set of tools that will enable me to do just that with all my books. I purchased all the tools but have yet to get it entirely functional because I have too many other things going on right now too. But with a little more time I will be set up.
I am anxious to discover just how large my personal collection is (my guess is about 2,000 books), to have it organized, an to enjoy the full functionality of it all. I will be happy to share before and after photos of my current mess versus my organized structure that is one of my primary projects now, including a new custom build home library with floor to ceiling bookcases in my office.
Thanks to all you folks in Amsterdam, Steve from Oklahoma City — Steve Copeland (USA) on Book Collector

Having fun
I did it almost twice now: I bought a book that I already have! So I have been searching for a program where I could scan the ISBN bar codes of all my books and let those go into a database. Well, I found the perfect program: Book Collector from Collectorz.com.
I bought the small laser scanner with it and started scanning the first shelf.

This is so much fun. Although the program doesn't find all my books (some of my quilt books are really old and not in print anymore and some front covers are missing), it is still worthwhile to get it all organized.
There's still a lot to be scanned, but once that is done, I can take the database with me and prevent that I buy the same book twice :) — Loes van der Heijden (Netherlands) on Book Collector

I seriously love this
I am a recently disabled Army Medic. I have some cognitive problems involving memory among other things. The VA informed me that I should look for software to increase my organization and to combat the memory loss.

I discovered a trial of your program yesterday. Awesome!
I hope this tool will help me organize my books as well as I think it will. It's easy to navigate (important for me!), it's a good memory support tool (no more lists of where I put stuff) and it had a trial (kick the tires).

I seriously love this and am going to recommend it to me Doc at the VA mental health clinic. It really is great.
Thanks for building it! — Ethan E. Harris (USA) on Book Collector
