This reminded me of Delicious Library, a program for the Macintosh for cataloging your home library. http://www.delicious-monster.com/ "Get your Mac, a webcam, and Delicious Library and rediscover your home library. Just point any FireWire digital video camera, like an Apple iSight, at the barcode on the back of any book, movie, music, or video game. Delicious Library does the rest. The barcode is scanned and within seconds the item's cover appears on your digital shelves filled with tons of in-depth information downloaded from one of six different web sources from around the world." I couldn't find a list of what these sources were. However, early on (2004), they were using Amazon's API to pull cover images, etc. http://arstechnica.com/reviews/apps/delicious-library.ars On 11/2/06, Jonathan Rochkind <[log in to unmask]> wrote: > My suggestion for an even better scenario: A person grabs a book off the > shelf, and enters the ISBN into an application they use for dealing with > books.
