Hey! Do you live in San Francisco? Have a library card? Then you can get free access to the incredible amounts of *real* commerical information online, including Lexus-Nexus searches, Encyclopedia Britannica, OED, current periodicals and the entire O'Reilly Safari library!
Man, I love living here. Thank you San Francisco Public Library! (And thanks Andrew Orlowski for the tip! He told me about it months ago, but I forgot to give him credit!)
