This is an excellent disk catalog program. It is VERY simple to use and very fast. One feature that it posse's that many of it's competitors do not is the ability to catalog a folder not just discs (this can be very useful). There are several programs on the market that catalog disks. DiskCatlogMaker, Disk Tracker, CD Finder are all solid and have been around (OSX around) for some time. It bothers me that CatFinder took so long to go to OSX and it still seems to missing a lot of features. Stick with this one or check out Disk Tracker. My two cents.
