Larry points out an interesting project called The Software Internet Database, the goal of which "is to compile the largest database of software titles and credits on the Internet. This includes all types of software such as operating systems, security, financial, mapping, browsers, video editing, games, word processing, and more. They have made a good start but still need more titles. Please take some time to submit missing titles so that they may compile the database faster." It would be informative to have a subway-map overhead view to know which of these are still available from their makers,have been folded into other products, or are now abandonware.
