The third (web) edition of the Encyclopaedia of Science Fiction (Clute etc.), possibly the most authoritative general-purpose source on SF, went on line in beta text earlier this week. Currently roughly 3.2 out of 4.2 million words are accessible, the rest is being uploaded as it's completed. For example, I'm referenced in a few entries, most notably one about Forgotten Futures, but there isn't an article called "Marcus Rowland" yet, and there are still a lot of articles that haven't yet been updated from the second edition, acting as place-holders for their eventual replacements.
Estimated completion date is the end of next year, but enough is already on line to be VERY useful, and the gaming content has been expanded immensely.
At the moment what they mainly need is bug reports; not so much omissions, which are only to be expected at this stage, but things like links that go to the wrong entry, weird behaviour, etc. But before sending anything in. PLEASE read the information on the news page etc. so that you know what the current issues are.
