This is the most comprehensive list of Bettie stuff on the Net ever. It tells you how much Bettie is featured on each site and what sort of Bettie-ness to expect. Ace!
Join one of two Bettie mailing lists here. I am on the bettie_buddies one at the moment so it has been given the Rollerdisco stamp of approval - five squillion points for friendliness! I'll check out the other in due course...
David Holle's Bettie site
I like this site. It has lots of links to all the useful stuff, including Bettie RealAudio interviews and the lark. V. good.
I Was A Teenage Betty
Bonnie Burton's site. Includes the eponymous story, pictures, Bonnie as Bettie (pretty damn cute!), and koolness.
Joe Bates' Bettie Page Page
Here you'll find (like I did - ahem) more Bettie pictures than you could possibly handle in one sitting. Everyone's favourites. One of the best sites I think.
Lou Nigro's Bettie Page Pages
This page has quite a good detailed biography of Bettie with some nice non-pinup pictures of her, as a little girl and stuff.
The official Bettie Page site
What else needs to be said here?
This person does a comic called Six Inch Stilettos, inspired by Bettie and the page shows a few panels featuring kool drawings of "Bettie".
