Latest software updates

I have been using Book Collector for almost a year. I am pushing 4,000 volumes in my library and would honestly be lost without it. It is easy to learn and use and has lots of great 'extras' like support for non-Roman character sets and provisions for almost every imaginable type of data capture.
I can't rate this tool highly enough: it's the best out there and I recommend it without reservation.

Would recommend this to anyone
I just want to say I really like keeping track of my books and keeping them in order even when i'm not around!
I would recommend this to anyone who loves books as much as I do! — Ainsley Marie Helgerson (USA) on Book Collector

My mad poetry collection obsession!
I have over nine hundred volumes of comtempoary poetry in my book collection which are valued at tens thousands of pounds. Keeping a record of them is critically important for any insurance claim I may make but more importantly, Collectorz allows me to readily access all the data of my collection like...search my collection on a wide variety of criteria, when I bought the book, have I read it, loaned it out, and, most importantly stops me from buying books I already own. (Trust me, before Collectorz I regularly bought books I already own.)
I also love that I can add book covers and I can customise the data fields to what suits my needs. I have been a fan for years and always will be. Highly recommended. — Gordon Connolly (United Kingdom) on Book Collector

Thank you for making it easy!
I have collected over 3000 books. At first, I was using End Note to build my library catalog. It became hard to use as I am also a comic collector. My wife retired and I was not able to get a copy of End Note for a new computer.
I found Collectorz as a new tool. I got the Book Collectorz first and converted my data. Then I got Comic Collectorz and began to enter my comics. I have entered over 800 new issues and I have ten boxes of comics I haven't entered yet. I also have music and movies to enter. I don't play or collect video games but I do have a growing collection of board and card games. For instance, several versions of Catan, Acquire, Monopoly, Poo, Cribbage (several boards) and many more. I need a collectorz version for Board Games. I have acquired a bar code scanner that makes entry easier. I recently converted to the Cloud. Thank you for making it easy! — Jan Fisher (USA) on Book Collector

Books Do Furnish a Life
I’ve been a bookish person all my life. I wrote in my autobiography, An Appetite for Wonder, as a child I was “a secret reader who used to escape to my bedroom with a book instead of rushing around outside in all weathers in true Dawkins tradition.” And still today in the age of electronic publishing, I cannot resist the lure of the printed book and I work surrounded by my collection of 3000 volumes. Now about to move into a smaller flat, I have it planned so that all three bedrooms and the main passageway are almost completely lined with books: “Books do Furnish a Room” indeed! In keeping with this, my next book will be called Books do Furnish a Life. It is an anthology of previously published Book Reviews. and Forewords and Afterwords to other people’s books.

Such a large library demands a decent catalogue, especially when moving house. Alwin Hoogerdijk’s Book Collector is as close to a godsend as my theology allows. As an old programming hand myself, I recognize from the inside just what a clever piece of software it is. I’d like to praise not just the product itself but the exceptionally friendly aftercare advice and help, from Alwin himself and his colleagues. I’ve lost count of the number of people to whom I have recommended Book Collector.

Your dedicated help has been invaluable!
Dear customer support,

Your dedicated help has been invaluable! You analysed our challenges, and you provided very precise instructions for us to apply..
So with your help we overcame today all our challenges, and everything in the new Book Collector version 18 functions perfectly well on the Mac and on the Mobile IPhone 7.

We are sincerely grateful for all you and Alwin have been doing so well for us. Please tell Alwin!
We shall recommend your firm everywhere we can in Denmark and abroad - and that is very easy to do also in practise: just taking the mobile up and showing the marvellous registration in the exquisite version 18! — Hans Chr. Wolter (Denmark) on Book Collector

Great App for Book Collectors
My previous book app was fantastic but the database seemed to revert sometimes to old outdated data. This app is an excellent replacement and you can choose to sync it automatically with the cloud so I know I am always working with the most up-to-date copy of my database. There are lots of fields to categorise all the information about each book to share with other owners of that book and additional data fields to add your own private notes. Very handy! It is also very customisable how you want to order and display your book library. — Celia Laurent on CLZ Books

Great app
I have added 100+ books in my collection in 2 days. A million times better than using a spreadsheet, and much less time consuming. — A Google user on CLZ Books

The Best App for cataloging your books
I’m up to 2454 books without a problem. I especially like the new placement of the sort/select buttons on the main screen. The developers continuously improve their apps in response to the users needs.
Kudos to all. on CLZ Books

Brilliant app
Your app is brilliant, there aren’t any other bookdatabase app that’s better than yours, I’ve tried them all, and none of them come anywhere close to your app. I hope you’ll keep supporting it for many more years to come. And remember, instead of giving up on the app in case of not earning enough to keep it going, if that were to happen, just raise the price or make a subscription price for us to pay every year.
I love your app! — Tine Sandvold on CLZ Books
