Latest software updates

I currently have entered in Book Collector over 9100 books and have about 2000 more to go. Your software is the greatest!
Besides organizing my collection so that I can know what I have read, I use Book Collector on my cellphone when I am in a book store so that I can determine if already a book in my collection or not, to prevent buying a duplicate. It has saved me spending money when I have forgotten that I have a book already. Also to know what format, condition, and cover, that I have, if I want to get a book in a different copy version.
Thanks again for you marvellous software and your advice.

Keep track of your books!
I have used this app for several years after many other trials that did not work well and I must say I have had the best customer service any time I have a suggestion or find an issue. As a book collector I depend on it to show me my existing collection as well as any library books I may read, when I am out at the bookstore. The new ability to separate into collections is great! I have books in boxes and now I don’t have to view them when looking at my collection list. Keep up the good work! — BookMage on CLZ Books

Geweldige apps de referentie voor verzamelaars
Ik ben al jaren trouwe fan van Collectorz.com hun fantastische apps. Bij problemen wordt je snel geholpen. Je kan tot heel diep gegevens inputten in de apps. Nederlandstalige ondersteuning. Ikzelf heb 4 van hun apps en ik kan met zekerheid getuigen dat Collectorz.com DE REFERENTIE is voor alle verzamelaars en in tegenstelling tot veel andere programma’s worden er continu verbeteringen en oplossingen en nieuwe functies aangebracht aan hun programma’s. — BassEddie on CLZ Books

The best
The best book database app on Android. Scanning is easy and fast. It also retrieves the exact edition of your book so your database is accurate as possible. This is a must-have for those who have hundreds of books in their home library like me. — Shane Comota on CLZ Books

Love your software
I love your software. I have a non profit called Book buddies and I was trying to keep a log of all the books we give away and I was typing out each title. Finding your sofware was very helpful. — Laura Williams (USA) on Book Collector

CLZ book collector
This is the library app I wish I had discovered years ago ! Once you have mastered the knack of recording your books it is outstanding in its attention to detail. I asked a question of the developer and within hours I received two helpful responses. I particularly value the genre section where you can add your own titled files. The tag section is also valuable for books which are a collection of themes under one heading. Like any good filing system the real test is how easy is it to retrieve what has been stored and this app passes with flying colours. — 19Bookworm on CLZ Books

Excellente application
Excellente application qui permet, grâce à la recherche en ligne, où par la saisie du code barre, de référencer et gérer tous les livres de sa bibliothèque perso, et d'éviter très simplement et rapidement l'achat de doublons en vérifiant directement dans le magasin (Soit par saisie d'une partie du titre, ou du nom de l'auteur, ou encore en scannant le code barre ) : efficace, fiable et rapide ! — Un utilisateur de Google on CLZ Books

So much more!
This app does EXACTLY what I need it to and so much more! Fast, smooth, versatile, easy to use, simple controls. Anyone with more than a handful of books or movies will really appreciate this app! Even if you don't keep books or movies (what's wrong with you?), use it to track what you've read or watched and what you WANT to read or watch, what was bad and what you want to recommend to others. — Ralph Joyce on CLZ Books

Works great
Brilliant app for categorizing your book collection. Recognizes most books via ISBN barcode, even non-english books. Author and title search often find similar books if your barcode is not the same. Full manual entry also works.
Support answers quickly and politely even to questions that can be found in the manual. — Jorn Haugland on CLZ Books
