I’ve had this for a while, but am just now in the process of finishing cataloging my library. This software is just the coolest thing since…something very cold.
Readerware <– site
They also have versions for cataloging your music and video libraries.
So here is what I do: I use my Cue:Cat barcode scanner* to scan in the books I own. It fetches information from the web (based on a list of sites I choose, such as Amazon.com) and gets the title, author, publication date, publisher… it even gets the cover art, plot synopsis, and “star rating” if that stuff is available. It keeps a handy database that I can search and display in various ways. It will even publish a webpage of my book collection if I want.
If the book doesn’t have a barcode, I can manually enter the ISBN number, or Library of Congress number… or if I can find it on Amazon or some other supported sites, I can drag the URL from the browser window on to this little target icon in the Readerware window and it will import the data from that page.
It’s too nifty for words. I lurve it.
Anyone else using it? I figure a group like this is just the sort of nerds to make use of such a thing 
*free if you buy the software bundle that includes the book, music, and video versions
Seconded. I bought the whole suite after a thread last week asking for recommendations for software for cataloging CDs. I like it, and found the publisher very responsive to the dumb questions I asked when trying to get started with it.
I got it last year and scanned in about a quarter of my books, then got sidetracked and I’m only now getting around to finishing. Take my advice: do it all at once if you can! It’s a pain trying to not waste time scanning stuff you already scanned in.
That sounds exactly like a program called DVD Profiler that I use to catalog all my DVD movies. Like Readerware, DVD Profiler accepts either a barcode scan or an ISBN number, and it downloads cover art, cast info, reviews, and other data into your file.
I have a comment and a question about the software.
The comment is that it bases the values on those it finds for the books (or CDs or DVDs) in Amazon or Amazon Marketplace. But so many people list items for a penny (presumably intending to make the profit on the shipping charge) that the software undervalues those items.
And the question is why does the scanned code for mass market paperbacks not return the ISBN? For trade paperbacks and hardcover books, the scanned number gets translated properly, but not for the mass market books, so I had to manually enter the ISBNs.
A lot of the mass market paperbacks have a second barcode inside the front cover that is the ISBN.
I don’t care about the “value” field so I haven’t really paid much attention. I just like knowing what books I have.
Blast! Looking at the overview, it doesn’t seem to work with comic books.
I can’t imagine why it wouldn’t work with comic books, although you might have to enter the data manually (unless they’ve got ISBNs on them). If you want to make sure, the publisher’s email address is support@readerware.com and he’s very responsive.
I love it. I got it years ago to sell items on half.com. Now I use it to keep track of my multi-media library. I’ve got all my books, cds & movies organized & cataloged. It came in handy when I insured the contents of my condo.
