Very useful
I can't remember how I came across the name now, and while I use both the books and movies/DVD ones, it's the books that's more of my interest. My system is that books I've read, and my mother also, upon their return, are put onto the Book Collector program, then stored in my garage. I print out the lists to take around with me for bookshops, sales, etc, that way I know what I've got.
I find being able to enter the exact ISBN for hardback/paperback versions very useful as I'm a librarian by trade so have used several different software programs for loans/returns. And the extra tweaks over the years have made things easier to use Collector, including the 'ISBN not recognised' so I can add those books to the collection/list. — Amanda Witt (Australia) on Book Collector

Superb software, easy to set up and ISBN scanning via camera makes it so easy to enter my books. Wish I had found it ealier. — sgur alisdair on CLZ Books

Fun!
I am having fun using the scan feature. It took a little practice but after about 10 books I feel like a pro. My book sale purchases will be loaded in no time. Except for those pre-ISBN books of course. Although they are pretty easy too. — A Google user on CLZ Books

Easy to use, syncing works well
An easy to use database for a book collection, which extends to eBooks as well as printed books. Syncing between devices is efficient, and looking up information about books - even old books before the days of ISBN - is fast. The interface is attractive. Where available, the app adds cover images automatically - but this is not always possible with older books. Books can also be added manually. — Michael Cayley on CLZ Books

Very simple
I just scan the book barcode and it's in my list, in alphabetical order by title. It doesn't have older versions of some books whose isbns have changed since the initial publishing but you can still find the book by author and title. — Adia Grigsby on CLZ Books

Praise!
I just thought I would drop you a note to say how pleased I am with your software. I have previously fiddled around with several competitor products for maintaining a database of my book collection - including apps which run on Android devices as well as Windows. I came upon Book Collector for Windows last week, tried it, and found that it is easily the best product of its class - absolutely well worth the money you ask for it (and probably much more!).

I can genuinely say this is one of the best thought out database systems I have come across in quite a long time, and the all-important user interface is really well designed indeed. It is truly a joy to use & does everything I need. The automatic data-entry mechanisms & scope for maintaining pick lists etc are exactly what is required to facilitate the arduous task of data-entry, and the facilities for listing, displaying images, sorting, and printing are superb and very intuitive.

I found that the competitor products quite often failed on automatic lookups via ISBN (particularly those systems designed in the USA), whereas Book Collector has very rarely done so up to now- I'm amazed at how often it finds details for books I have which are 50 years old or more & don't show an ISBN (or even an SBN!).

So congratulations on a really brilliant piece of software - I would recommend it to anyone needing to catalogue their book collection. — G C Pearce (United Kingdom) on Book Collector

Where have you been all my library?
Fantastic app! More than just a "you enter it all yourself," it references a database and enters most of the information for you. Less than ten books entered and only two were not found. Both have ISBN numbers but seem to be self-published, so not expecting those to be found. Even $15 to get full use of the app is definitely worth the price if you have a large collection. Highly recommended! — The Kitchen Witch on CLZ Books

Love it
I've used other cataloging software and this is the best. Easy-to-use interface; cataloging by ISBN is simple. And love being able to access my collection from all my devices. — A Google user on CLZ Books

Handy when I'm book shopping
I use it to keep track of what books I have, so that when I shop I know if an interesting book would be a new addition to my library. I find it easy to add books by scanning ISBN bar code on back cover or inside cover, which works for almost all books. Older books (~40+ yrs) that don't have recognizable ISBN, I search by author and title then select to add (still relatively easy). In very rare cases I've added a book manually and included the front cover picture that I took myself. — C101481 on CLZ Books

Me gusta
Tras usar otro catalogador, éste me resulta más práctico, sobre todo al usarlo en paralelo mac-ipad. Me gusta mucho que la base de datos del isbn (lo que más uso) sea más amplia y de acceso más libre. Algunos aspectos pueden pulirse un poco, pero globalmente he mejorado. — Lpf64 on CLZ Books

Awesome
Awesome update Alwin! Much more user friendly...and going to your website to add the unknown ISBN was a pain. Thanks for continuing to make the program better! — Scott James (USA) on Book Collector

Book Catalogue
Just started to use this app. Scanning of Isbn is easy and the speed of response is remarkable. Lots of customisation possible so no excuse for misplacing a book. Will probably end up paying the one off fee for use with more than 100 books. — RNW61 on CLZ Books

Fantastic!
I love this application. Whether you have a book collection you want to want to catalog or just want to keep track of what you have read you can't beat it. Just scan the ISBN number and the app pulls in a ton on info on the book. You can create folders if you choose. Extremely useful. — Wilfred the Barbarian on CLZ Books

Fantastic app
This is a great app for looking after a book collection. It is quick and easy to add most books (simply scan the ISBN or type in the book title). — Specul8 on CLZ Books

So far so good
I've been looking for something I could inventory my collection for awhile now. This is the first I've found that allows me to scan via ISBN and manage my collection via app or PC. — Darrel Spurlock on CLZ Books

Couldn't have been simpler. Entire bookshelf in about 2 hours
Phone with scanning screen in one hand, pulling out book enough to scan isbn with other hand, set aside problem barcodes for later (additional stickers, hardback books), very very easy. Great app. If it had worked at the end of a selfie stick - I wouldn't have needed a ladder - lol — Eamonn Edwardo on CLZ Books

Easy to use
I have been very happy so far with this app. I especially like the scanning feature that allows me to scan the ISBN instead of having to type each number in by hand. The cost to upgrade storage is on par with other apps and websites I have checked out. — +(A-rOd)+ on CLZ Books

To the making of many books
This app is great. I've started cataloging my books. Pretty easy scanning the ISBN. They also have one for your music. Someday I may get to my CDs. — Kickin' heels on CLZ Books

Eindelijk overzicht van mijn boekverzameling
Prima app waarmee je supersnel via scannen van het ISBNummer overzicht hebt over je boeken. Heb ook mijn ebooks erin gezet. Is heel fijn dat ik daardoor van die boeken ook een korte beschrijving van het verhaal heb. — F. Raesen on CLZ Books

Geweldig handig en effectief
Zeer handige app en programma op je PC, ik gebruik het op mijn iMac, altijd een overzicht van je boeken bij de hand. Ook makkelijk bij te houden welke boeken waar staan, huis, praktijk of universiteit, bijhouden wat je aan wie uitgeleend hebt. Handig toevoegen door via de app isbn nummer te scannen. Graag zou ik ook via de app willen registreren of een boek uitgeleend wordt of teruggebracht. Nu kan dat volgens mij alleen nog maar met de desktop versie. Echt een aanrader! En de licentiekosten heb je zo terug omdat je nu altijd overzicht hebt van je uitgeleende boeken. — MartinPJ on CLZ Books

If you wanna best
The best of the best I've ever seen / used. Everything works as described. The OSX version is highly complex (mean: it knows everything), yet very easy to use, and all customizable! All you can try free with the sample database, or even with 100 own books. Infinite easy to sync between OSX and iOS applications. The mobile application can also scan the ISBN, so you can promptly import a new book. If you do not find a book in the central database, you can upload, and after that everyone reach it. This is great! On the other part, the mobile version is always with me, so I know what I already have and what's on my wish list. Anywhere and anytime. This is essential! But the most superior is the SUPPORT. They are fast, nice, helpful, effective. This is at least 6 stars (from 5)! — Apple-Zed on CLZ Books

Tof
Goed programma, met een grote database om je boeken in terug te vinden, het scannen van isbn nummers werkt uitstekend. — MaSaGhi on CLZ Books

Best I've found
While it's not perfect, this is the best application I've found for keeping a book catalog synchronized between several Mac computers, iPad and iPhone. I recommend it; if you need very detailed records, the Mac or Windows application is more complete and works perfectly in conjunction with this one. Barcode scanning for ISBN works well; note that some books (mainly from the 1980s & 90s) have a UPC code instead, which doesn't identify the book. — Anton Rang on CLZ Books

I want more!
This software has been glitch free, and easy to use. It's had every book I had to enter by ISBN that was too old to be scanned. I haven't tried entering a book that's pre-ISBN yet. If you figure out how to tie this in with book recommendations, missing books from a series, and link to an online book seller, you would have an amazing killer book app. I can see already I'll want to bump this up to a higher database count. — Misterbear Fapp on CLZ Books

I use this all of the time
I currently only use this for books that I have or read. For a while I keep track with paper and digital notes. But still a lot of typing. This app allows you to scan or enter ISBN number and save all the information quickly. Now when looking at books (hard cover or ebooks) I quickly know if I have it or already have read it. I am sure this app could be used for any collection.???? — the great Nerd on CLZ Books

Was hesistant due to cost, totally worth it
Very impressive database. It's been able to recognize various pre barcode books with no problem based on isbn. — TheWillypedersen on CLZ Books

Geen Billy boekenkasten meer
Spijtig voor Ikea, maar sinds ik book collector software gebruik, heb ik geen Billy boekenkasten meer nodig. Ik lees veel en geef mijn boeken altijd weg. Toch wil ik als geheugensteun weten welke boeken ik gelezen heb. Book collector fungeert voor mij als virtuele boekenkast. Neemt geen ruimte in, verzamelt geen stof en altijd bij me als ik op reis ben. Alle titels met omslag en flaptekst altijd en overal (op desktop, ipad, laptop en iphone) raadpleegbaar. Heel handig als tijdens sociale bijeenkomsten het onderwerp literatuur aan de orde komt.
Wat book collector voor mij waardevol maakt, is dat ik op titel, schrijver of ISBN alle info vanuit een database in mijn systeem kan opslaan. Ook het synchroniseren van de verschillende apparaten via een cloud functie maakt het voor mij ideaal. Tenslotte: de zoekfunctie maakt dat je nooit lang in je 'boekenkast' hoeft te zieken naar dat ene boek dat je zo goed vond en aan iemand wil aanraden. Naam van schrijver of deel van titel is voldoende. Krijg dat maar eens voor elkaar als je niet in je eigen huis bent. — Justus Kramer Schippers (Netherlands) on Book Collector
