Have you ever tried to find something on the Internet but every keywords are linking to an other event? Like looking for the 2001 Worldcon or the results of a ski competition in 1999. I’m sure these events are documented on the web but they are harder to find as new events are “masking” the results. Internet is suffering from a kind of strange memory problem. Its our biggest shared repository of facts on human life and its a looser on how to recall something. Search engines are part of the solution but they are not so great. The best solution is, as its always been, find somebody who know and follow its lead to an other person. In time you will find what you are looking for.
