Heads up, academics and A-grade book geeks – here’s a site you’ll want to be adding to your bookmarks for research purposes. ISBNdb, as its name suggests, attempts to do for books what IMDB does for movies. From the FAQ page:

ISBNdb.com gets the data in a unique way – it scans libraries all across the world for book information. The scanning is random and similar in a way to how general purpose web search engines scan web sites.

Scanned results are then parsed and stored in a searcheable and browseable database that you see here on ISBNdb.com. An attempt is made at cross-indexing the database by author, publisher, category and so on. Cross indexing is still a work in progress and is likely to improve as the time goes on.

For each book you can see records received for it from different libraries, you can download original MARC record for the book as it was returned by the library.

Another interesting feature is ‘Books on the Same Shelf’ — it allows to quickly look up similar books in the same way they would be placed in a real world library. Currently, two classification systems are supported — Dewey Decimal Classification (trademark of OCLC) and Library of Congress Classification.

Starting late 2004 we also started scanning book merchants for best book prices. You will see best prices for new and used copies on all book pages below the left menu in most cases fraction of a second after you load the book data. Active and historic prices are also available through the data access API.

I just lost half an hour of productivity to that thing without even trying! And that API is just begging someone to do some good mash-up work; it’s the sort of thing author- or genre-specific fan sites could get some great mileage from.
