Want to be able to peruse your media collection with a click of the mouse? Delicious Library is a MacOSX program that allows you to create a digital archive of your entire media collection. We ditched our jewel cases about a year ago and can appreciate the need for knowing where something is stored. For our small DVD collection, however, this is a bit of an overkill. However, if you need to know where things are, this could be a great way to organize things.
There are many other cool features, including your own virtual library where you can marked items as checked out (to friends and family), and be reminded when they've had things awhile. Head on over and download a trial copy to discover all that it can do. Available here for $40.
