Latest software updates

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!

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.

Lost without it
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. — Gary Mackelprang (USA) on Book Collector

The absolute best
Best library so far. I've tried plenty of other apps for my collection but this is the absolute best and easiest to use. Not confusing. — Yahvonne A. Reddy on CLZ Books

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

Love this program
I really do love this program. I used Delicious Library for a number of years but when I moved to a new iMac I had difficulties porting my data base. I stumbled upon your program and have never looked back.
BTW, my wife and I, together with some friends, are going to be visiting Amsterdam next year. I am looking forward to seeing the Vermeer’s. — Joseph Shidle (USA) on Book Collector

Easy to use and efficent
I'm only about 100 books in, but this makes it so easy to scan our library. This app is really user friendly. I can't believe I didn't get this sooner. — Nicholle Holycross on CLZ Books

Love this app
I absolutely love this app. Easy to use and helps me keep my growing library in order plus I can take it anywhere and if I come across a book that I'm not sure whether I have it or not all I have to do is search it in my app. Love it!! — Brenda Cosner on CLZ Books

Always have my list with me
I have this software for my 800+ books. A great way to always have my list with me, to prevent the occasional "double purchase" of a book. I recommend to you for your library. — Thomas L Hiegel (USA) on Book Collector

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

A great product
We are using this at our car club Library with 5000+ books and 500+ lenders. A great product, at a very reasonable price, easy to use, easy to maintain and runs on machines with minimal resources.
I recommend this product to anyone wanting a maintain a small library....and I am an IT manager at a library for a living. — Neville Butler (Australia) on Book Collector

Just what I needed

Saves me from buying duplicates
I have been using this software for years to track my library as well as all books given as gifts. It saves me from buying duplicates. I also know exactly which shelf to find a book on. — Carol Bostian (USA) on Book Collector

Paid for itself
Fabulous program that's already paid for itself in saved duplication. As a portable catalogue of my library I couldn't ask for better. The seamless integration between phone app and desktop is fabulous. — Micheal O Doibhilin (Ireland) on Book Collector

Marvelous software program
Collectorz is a marvelous software program. It is so intuitive, beautifully designed and user-friendly. I have a fairly large library and I have never had it more cataloged and organized! — Dan G. Olson (USA) on Book Collector

FABULOUS!
Been using it for years. My book buddy and I can check which books we have in order to avoid duplicates. Also use it at the bookstore and library to see if I have it or read it. — Lucy Looney on CLZ Books

Great!
It's been working great for a few years now. My only comment would be the plethora of options available means I can spend even more time in my library making adjustments. — A Google user on CLZ Books

A real time saver
I love your programs (I also have the Music Collector). I have an extensive library of English and German language books. A substantial part of my library is reference material and Book Collector and its search features are a real time saver. I currently employ an IT student for data entry and proof his work on my iPad. The next step for myself will be entering all my eBooks. I use the iPad for my own data entry. Works great! — Irene Hahn (USA) on Book Collector

Greatest library software
I have a vast library and the thought of getting software to automate it had me horrified. This software was well priced and the customer service has been tremendous. They have gone the extra mile to help a non-computer guy like me to make sure I was able to get up and running. When I have had trouble because of my ineptitude the customer service has gotten back up and running again. I will never stop using this software. — Ron Clites on CLZ Books
