Books / CD Management App

[hb2p]

I am looking for an app that will allow me to scan the bar codes of my CD's and books so I could have a record of the ones that I own. This way when I'm out buying books/CD's I can know what ones I already own.

Have any of you seen an app (or 2) for this? I've seen a similar app for Android that does DVD's.

Thanks in advance,
