This is cool...a spot for "OSReSearch". It's a Google based search engine for OSR-related material; a list of indexed sites is here. Searching "Holmes Basic" brings up various blogs (including this one) and forums (Dragonsfoot, OD&D Discussion, Acaeum). Nice place to search all of these at once.
It also has a brief intro to the OSR, so I've put a link to the engine in my little OSR logo to the right.
The creater, untimately, also has his own blog - http://untimately.blogspot.com/ - and is a member at OD&D Discussion.
