I don't know a great deal about Delicious Library but will it work with the new iMac built in iSight? The bar code scanning seems a really good idea. And, did I read something a while back that they've stopped development of it? Answered my own question. Here's a response from the company: "We are aware of an issue with camera focusing that prevents Delicious Library from scanning barcodes with the built in iSight, and we are working hard to remedy this. Look for an updated version of Delicious Library soon!"
