Latest software updates

Today, while flying from Washington DC to Boston, my daughter texted me asking to buy a book for school. Thanks to the Collectorz book app, I was able to tell her that we already own it, where it is located, and text her a copy of the cover. All while flying at several thousand feet. I love this app! — Ellen Edge (USA) on November 28, 2018

Scan and add, done!
I used to write down the ISBN's of books I wanted on my wish list. Now I just scan and add them to my wish list in seconds. Great program and phone app. — Dave Bakke on CLZ Books

Thanks for all your help
It is Thanksgiving Day here, and while I have a lot to be thankful for in a life that has been richly blessed with friends and family, I must say that I'm extremely thankful to you and the whole crew at CLZ. I'm constantly learning new things in how to use this program and I'm so grateful that no one ever makes me feel stupid or silly (even when that is the case)!
So, thanks for all your help. — Peggy Beatty (USA) on Book Collector

Always good
I’ve used various collectorz software for years - Games being the only one I don’t use - and the iPhone apps have been great, as usual. — Nathan Elke on CLZ Books

Awesome App!
I was concerned after I had read a few reviews of Apps that can catalog your book collection. Then I read the reviews for this App! I paid 14.99 for the App. I am well pleased as I am not a librarian by any means! However with a little trial and error I quickly figured out how to either scan my books or type in manually. I think this is a great feature as not all books have a code. Also many of my books are quite old.
It also let me personalize if I wanted to! In fact I just put where the book was located in my home on what shelf. No labels had to be added! I love this App! Also I can share between my phone and iPad! — Mommee Dearest on CLZ Books

Love this program
I do love this program to keep track of my books. I love reading. This has helped me not buy duplicates (partly why I want kindle books added to my list). Been known to buy a book twice because forgot already purchased it. Lol. Now I can look it up on my phone so I don’t do that. — Sara J (USA) on Book Collector

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

I'm a real 'book-aholic'
My collection of books has grown till more than 8900 books today. For years ago I used a little library program I'd found in internet. It was for free and so it has its restrictions. I don't know no more the year I heard the first time from Collectorz.com. It must be one of the starting years of this excellent program. When I used it the first time, I immediately was devoted to it: now I had the opportunity to find each single book any time in any place!!! From the fast 9000 books I have entered 6450 books in this wonderful program bookcollector: complete with all the data of the books: title, short content, a picture of the front and the back, something about the writer, the edition, the date, the genre, the purchase, the price, the dimensions, the place where to find the books: the kitchen, livingroom, the corridor, the study room, or in my bedroom. And finally I can see the on witch shelf of my big library the book is and or I've lent a book to one of my friends. Since I use this program I can find everything and I never have lost one of my books no more.
A few years after purchasing and using Bookcollector I bought MovieCollector and MusicCollector too and the possibilities to order my collections are endless!!! These three great programs are really indispensable for me! So all my praise goes to Alwin and his team who enabled me to enjoy optimal my collections. — Hub Koken (Netherlands) on Book Collector

Great app for tracking the books you own
So easy to add books and there are several different ways to add them - all very easy. Love all the information this app pulls in. Especially love that I can search various ways. Great app for tracking the books you own. — Deane Greene on CLZ Books

Ideal product
I've had Book Collector for quite few years but probably don't use all the features. I have a couple of hundred speciality books which I loan to people and I found the loan management facility so easy to use, I haven't lost a book since starting to use it. Entering new books into the catalogue/database is also very easy. All in all, this product is ideal for me and the upgrades to the app are absolutely trouble free. — Ian Wilson (Australia) on Book Collector

I have always had a lot of books and for a while there my job had me moving from state to state a lot. Books were lost, baling books for a removal became harder as I got more and actually being able to say what they lost was a problem. When I got this app a few years back it was fantastic. I can now have my library in my pocket when I shop and can see what I need, if I have a book already even if they release it with a new cover and title and I can put together my Wishlist meaning my family can now get gift ideas from me instead of guessing. It’s the little things done right that make this a brilliant app. — Pete_11 on CLZ Books

Awesome program
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. — Angèle Young (Canada) on Book Collector
