18:46:03 28-Jul-2006Looking for that dreadfully expensive volume for your studies? Selling one on eBay? Now you can check what the historical price trend for the book is and see if you're getting a good deal.
Here is an example: Electronic devices and circuits
The earliest prices we have are from December 2004. The total now in the database is close to 30,000,000 price records.
And of course you can get all the same data through the ISBNdb.com API. In fact, the API have had this practically since the beginning, and now the website is up to speed too.
Hope this will be useful!
