ISBN Database Software

This is the best cataloguing application and the mobile version is a god send with the ability to scan ISBN bar code.

Thank you for allowing me to spin the pie chart at the bottom of the statistics page - 10/10 app, does as advertised, my only suggestion would be to add a more satisfying beep sound when you scan an isbn:)

Facilidade em adicionar livros manualmente e por ISBN Facilidade em filtrar livros por qualquer característica.

I have used this program for over 4 years now! Works immediately after downloading and networks with the current ISBN database. Responsive customer service is another plus. IMHO it’s the best book cataloguing app out there!

I have been using the CLZ apps since they came out in 2019, but I have been using the desktop program since 2002! If you want to catalog your books, there's no easier way than to use this app. It allows you to enter an ISBN and finds the book details for you to add to your collection. You can add further details, etc. You can also assign it as "In Collection", "Wishlist", "On Order", etc. When I go to a bookshop, I can see my wishlist! If you have the desktop app, you can sync back and forth!

Looks good and works brilliantly! Just add books by isbn works great and if a book hasn't been added you can do that yourself and that's pretty easy too. What I especially like is there are two different coverviews. Option one; everything is boxed in and looks very near, the other option has the same height for every book, so wider books will be displayed large as well.

I was using this app to catalog the 4000 books in my collection. After about 1000 bucks I upgraded to an iPhone 14. It turns out that the camera on the iPhone 14 will not properly scan the barcode. I contacted the developer and they immediately got back to me. They kept me informed of the progress of the upgrade. They have subsequently fixed the problem and the app works fine now.
The app itself is particularly useful if you have books published after 1967 - you can just scan the ISBN code. You have to manually enter the name of pre-ISBN books, but usually the database that the app is connected to will have some of the information. You can then incorporate that information into your collection database.

ISBN code scanning works nicely, very helpful.

First up - really impressed with the rapid response from tech support - it was much appreciated (how to add multiple authors to a book).
I've been using BookDB, which has been great, but remembering to export to txt and then copy to my phone so that I didn't buy duplicates in the 2nd hand book stores was getting tedious (you may have noticed I have a lot of pre-ISBN books). So the search was on for something that would allow me to maintain a sufficiently comprehensive database on my laptop and sync it to my phone with minimal effort. Your team has delivered.
Mapping fields between BookDB and Book Collector took a bit of trial and error (mark all as Skip Field, then go back and set correctly) and there are a number of notes I'll have to port manually (eg first edition/signed by author/family connection, austerity printing c WW2, condition of binding etc), but all in all, this is a great product - and the cost is extremely reasonable - I've definitely spent more than that on a single book, so the potential saving in avoiding duplicates is real!

This app takes a bit if getting used to at first, but the catalogue is extensive, and most bar codes and isbn numbers can be used to autofill a good chuck of a collection.

Very impressive database. It's been able to recognize various pre barcode books with no problem based on isbn.

I've been using it now for a few years to manage a 1000 book library collection for my quilt guild. What I really love is that the Collectorz team is constantly making improvements to the app that make it easier and faster for the user to manage their collection. The team is responsive and genuinely interested in what their users have to say about the program. The app is simple to use, and very intuitive. You can slice and dice your collection in any way you want to see what you have, and there are a lot of customizable fields if you have specific interests. The connection to "core" is flawless, and simply by putting in the ISBN from the back of a book you get all the information you need in seconds. The price is very reasonable for the value you get from this app.
While I haven't used their other products, I'm sure they are just as refined and useful. Thank you CLZ team, great job!

El uso simultáneo con el mac y el iphone me da mucha flexibilidad, aunque es más completa la batería de datos del programa para mac. Sencillo de usar, el escaneo de isbn (hay algunos que aún no localiza) es de lo mejor para obtener datos rápidamente.

This is an excellent app that provided me with the means to create a decent inventory of a small school library. It is very accurate and user-friendly and I am able to create new titles, link existing ISBN's and access my numbers instantly. Highly recommended.

I have been in the process of moving house and clearing out a family storage unit, thrilled with the books I’m finding, remembering and hoping to organize them all into a great library. I was seriously thinking of hiring a librarian to help me with all this when I found this fabulous app. I am able to seamlessly add volumes by isbn numbers and have manually added obscure volumes, photographing the covers and noting their particular histories.
I have been so eager with the newly discovered app, trying to get up to speed, I quickly asked support for some features that I subsequently discovered on my own. I was pleased to get an equally quick answer to my query— how to print out my lists— and can’t wait to do more. I may still hire someone to help me but with this app I am assured that even a student will be able to do a thorough, professional organizing of my library.
Bravo! Six stars!

Love working with this app. Books can be entered by scanning their barcode, so it’s a powerful bookcataloguing system that’s very quick and easy to use. I make heavy use of options that allow you to personalize the settings and stored details, so it’s tailored to my needs.
Over the 7 years that I’ve used this app, I’ve seen lots of improvements. The developers are in-tune with their customers—if we ask for new functionality, it’s actually considered and often implemented. I even had the owner email me when I had an issue!

An excellent app which is very sophisticated and powerful. A delight to use and Cloud synchronisation is a major asset as is the camera based ISBN scanning and adding feature.

If you are a book collector (a bibliophile!) then at a certain point you can’t keep an accurate track of your collection in your head. This becomes a problem when you are in a book store, you see something interesting and you really should know if you already have that book, or that particular edition or if the asking price is a bargain or too high. CLZ Books on the iPhone is a perfect way to keep track of not only what you have in your collection but also what is on your “want list” with lots of details. Using a book’s ISBN code, CLZ Books will fill in most of the critical data, including an image of the cover, and it is quite easy to add the missing pieces that are important to you (date of purchase, which bookstore, etc.). All this information sitting there sitting in your phone ready to be tapped into on a moment’s notice. I’ve been a CLZ customer for many years, starting when only a PC version was available. I didn’t choose their program lightly. It was just the best one available at the time. Their constant improvements and their expansion into the Mac world and then onto the iPhone has confirmed that my early adoption was valid and I still am a total fan of their app and believe that the price is a bargain for the product and the service.

I have used the book cataloging software for many years to catalogue the many (many) books we have stored in numbered boxes and bags in our loft. I had also catalogued the books belonging to our local Embroidery group. We wanted to make full use of the group’s books during lockdown and with the superb help of the Collectorz support team, we set up a separate Library and included, on separate sheets, books belonging to members who were willing to loan them out. Until face-to-face meetings resume, we have an ad hoc doorstep delivery system in place, supported by the Loan facility within the software.
The CLZ Barry scanner enables members to scan the barcodes of books they are willing to loan and email the ISBN numbers directly from the App to our Librarian for logging. Subject to Covid restrictions, we can work directly with any member who has as many books as me, to load the books directly. It is particularly helpful to be able to sort on technique, subject etc as well as author and title.
The software works and the support team are easy to contact and really helpful. Highly recommended!

I love to organize and as a homeschool mom I have nearly 1,000 books. Keeping them organized would be such a chore but this app makes it so easy! I love being able to scan the ISBN of a book to add it to my booklist. And pro tip: if you have lots of older books with no barcode, I’ve found the fastest way to enter them is to go to the keyboard for typing it in, and then click on my microphone and quickly say the numbers. Works great!

I own over 540+ books and this does a nice database job. I buy a lot of HISTORY books and computer books, this works great to prevent duplicate purchases. When looking at new wish books like the wish list for recall when asked for gift ideas. Like the detail and the book cover pic to compare if purchase or already own. Easily search when shopping especially mobile. Alwin & Team constantly adding new features Via enhancement updates. If there is a problem The Team addresses it very quickly although i have owned for many years and haven’t found too many issues mostly just added enhancements. Highly recommend, cost effective and enjoy it so much purchased several other of his inventory products. Couldn’t add to collections without this product And adding via Title or even better ISBN code is great. App is flexible and allows for cover graphics override so can match exact ownership version. Highly enjoy & Recommend.

I have really enjoyed the use of your products over the years. The Books and Comics in particular made cataloging my collections a whole lot easier to finish and sort. It was really nice that I was able to add most items without having to enter each piece of data separately, like some of the other software out there.
What seemed like an endless task of adding 3500+ paperbacks and hardcover, became a joy to do. The use of a barcode reader just made it that much faster. I still had to manually input a fairly large number of books as they were printed before the barcode system came into being, but even that, for the most part, was reasonably easy to do by using the ISBN. A bit tougher to enter the ones without any ISBN listed, but there the search by title and author made things doable.

I also wanted to take a moment to thank you for creating the Book Collector software. I have an extremely large book collection that I need to downsize, and I was hoping to find a tool that would allow me to easily catalog my books so I could determine which ones to sell, which ones to bring to the used bookstore, and which ones to keep. I also wanted to capture other details about my books. I discovered your website by pure chance through a Google search, and I am so happy I did since your software does everything I wanted to do (and more)! I having been working with data for 35 years and find that most tools lack the functionality that users would like, but that is not the case with Book Collector. It is very intuitive and user-friendly, and I have been able to figure out how to do something without looking at the manual. The app is a life-saver too since I found it challenging to use my web cam to scan the ISBNs. With the app synchronization, this work is very easy.
Thanks again for the wonderful resources you have created.

I have a home library of around 350 books, and growing. It was getting to the point where I didn't know which books I owned already. I got CLZ as my home library database and have really enjoyed having it. It's super easy to scan books in or type in the ISBN, and it's easy to search as well. So when I'm at the book store I can quickly see if I already have a book or see what books I'm missing from a particular set. Definitely recommend for anyone with a large home library.

The app was able to easily read bar codes from the last 20 years. Took a little longer with 30-40 year old books. A lot of books had UPC codes and the app easily identifies them. ISBN searches were a breeze. That I could add cover pictures was great. Only complaint: the title search engine is weak. One letter mistake and it couldn’t find a book - “if” instead of “of”. The I and the O are next to each other on my iPhone. But overall I was able to catalogue 99.9% of my more than 1000 books!

I've been using this app for about 2 months, and couldn't be happier. I'm using the app in a slightly unconventional way - not for a personal book collection, but for the school's PTO book collection. The cloud feature of the app allows me to upload all our books, for parents / students to view what's available, and the flexibility of the app allowed me to customize each record to allow for people to select books they wanted.
Populating the app was very simple by scanning ISBN barcodes, and even when a barcode wasn't available, a manual entry was very easy to do. I did do some editing of records to ensure consistency across our database, but this too was very easy. I also edited a number of cover images by adding my own - again very simple a straightforward!
I highly recommend this app. Not only is it comprehensive yet simple, it comes with a first class support team. On occasions when I have had questions, I have dealt with three different support analysts, and each has been highly responsive, knowledgeable and friendly. You can't go wrong with this app!

The ISBN feature works like a charm!

This is the fourth CLZ app I have used and they're all of equally high quality. Easy to use and constantly updated so they keep getting even better. Adding a book is simple - just type in the ISBN or title (or scan the ISBN bar code) and unless it's a really obscure book the details pop up from the huge database. Even if your collection is in the thousands this app will store them with ease and display them in any order you choose.

I Like the fact That I’m able to scan my Books To see How many I Have in my Collection. That way I Know What Books I Have.

So far I'm able to scan my books and list them. This app is what I need. Extensive library! I'm just getting started.
