Subscribe to Book Price Changes at isbn.nu

I always been a fan of isbn.nu since Gary introduced it to me about 2 years ago. The other day, Glenn Fleishman (the creator of the site) made a neat upgrade:

“I’ve long thought about adding a feature that would allow people to sign up for notifications about when a book price changed or became available at a given bookstore. Perhaps you were waiting for a used copy of the book, or wanted a book to drop below a certain price. I may still offer email notification, but it struck me that I could immediately provide an RSS 2.0 feed with very very little effort.”

“The pattern, by the way is http://isbn.nu/ISBN.xml. For instance, to monitor my book Take Control of Your AirPort Network, you would type the URL http://isbn.nu/0321321162.xml into a news aggregator or even (in intelligent aggregators) just http://isbn.nu/0321321162 which would allow the aggregator to find the XML-based RSS feed on its own.”

I’ve subscribed to the feed for my book to test the system. Great idea Glenn.
