Well, not really. I think you are joking about the URL. This is actually a decent example of where knowledge that individuals have can be useful. Has Saturn Publishing gone out of business? Maybe this Saturn Publishing is the same one that published that CD a long while back. Maybe they are still in the business of publishing game collections and it is worth contacting them. Possibly the point you are making is that publishers aren't worth tracking because the information goes out of date, but I disagree with that. It does seem a little silly to use a forum to make lists of publishers, which is why I suggested indiewiki as an alternative.
The best way to get a list of publishers who aren't dated would be to visit the software sections of a Wal-mart or a K-Mart store, and note the URLs of such publishers.
That would be the best way to locate a subset of publishers--the larger, more obvious ones in the United States. But what about smaller publishers that only have distribution in store chains that reach some states? Or publishers in other countries? Or magazines with promo CDs? Or demo discs that are given away at retail outlets when you make a purchase?
Again, I encourage people to add publisher names in the wiki. And if there is an existing free resource which already does a good job of listing software publishers, please let me know, and the wiki can link to that.
