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.

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

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

A+ for service
I would like to mention that I have used Book Collector from the early days when I think it was your only program. I am always impressed by the quick service provided.
I greatly appreciate all the help that you have offered (i.e. as before you all get A+ for service) — Chester McFarland (USA) on Book Collector

This is the best app to document your library whether it is digital or actual books. I love this app and totally recommend it. It is worth the cost. — Stephanie B on CLZ Books

No more duplcates
I have over 800 rpg books and box sets and this keeps me from buying duplicates. And some of the rare vintage books can be really expensive. So I consider it an investment of saving me money from not buying the books I don't need. — Craig Daley on CLZ Books

Thank you CLZ!
I am amending my review to reflect the wonderful customer service I have received, as well as the functionality of the app. Of all the apps I tried to catalog my antique book collection, CLZ Books is my favorite. I like all the various data you can input, including reading date and price. My collection is from well before ISBN numbers (being published prior to 1900), so ease of manually inputting all of the data I want is important to me. I did try out scanning on one current book and it worked very well, but I haven't explored that side extensively. I am excited to unpack the rest of my collection and get them entered into CLZ Books! — RockyMtnSky on CLZ Books

i am so very pleased with this product and it has made my new cookbook collecting hobby a cinch to track. it does exactly what it claims to.. buy, scan, shelve...and enjoy! — Brian Phillips on CLZ Books

Very good catalog
I've been using this for a few months now for my modest (~5000 books) collection. The iPhone and iOS apps are handy for on-the-go access, adding books, and basic editing, though the Mac app is more full-featured. Synchronization has been flawless. The ability to check my catalog while in a bookstore is invaluable. — Anton Rang on CLZ Books

Must have for book addicts!
I have used this app since it was born, starting on Windows desktop and watching it grow, to newer platforms. With close to 18000 books, It has saved me money...... Before I purchase a new book, I quickly check to see how I rated the author and to avoid buying duplicate books.
Updates have always been smooth and their support is outstanding. — Still retired on CLZ Books

Amazing app
Best way too know what books you own. Never worry about owning duplicate copy's again. It's amazing. Still loving the app after all this time. — Aimee Schlosser on CLZ Books

Multiple Collections!
I am so happy with the newest version of CLZ Books. Now I can finally keep separate lists of my “regular” books versus those in my craft library. It’s very easy to transfer books to a new collection if they’re already in the database, so you don’t have to re-scan anything. The only thing I would tweak is to have the Search function work across collections, rather than just the one you’re currently viewing.
I use this app in conjunction with the Book Collector desktop app, and the collections sync nicely from one to the other. The collections are also easy to view in the CLZ Cloud.
I also use the Music and Movies apps and desktop versions. This collection of software adds value to my day-to-day activities, and is the only software I ever thought worthwhile to pay for a service/renewal plan. — LMB0001 on CLZ Books

Fantastic program
Yes, it's an expensive app, but both my husband and I collect book series that have hundreds of titles (Doctor Who and Star Trek) and not buying duplicates has saved me far more than the price. The wishlist feature is also great for when you're at a bookstore with only enough money to buy one book,and you find five more you want; you can scan their barcodes and remember to get them later. — Andrea Cook on CLZ Books

Love it
