Have a site you want me to link to? Drop me a line and I'll post it. Some of the folks in the book have their own sites or recommend interesting sites. There are also a few that I've found helpful:

Elsa Marley's site
Barry Melton's site
Planet Drum (Peter Berg)
Paul Krassner'site
Bob Zellner's site
Dave Meggyesy's "Out of Their League"
Country Joe McDonald's site
The Diggers
Vietnam Veterans Against the War
Chicago 8 Links
Free Speech Movement
The 60s Project
Stew Albert's site - Stew, who was at People's Park and was a central figure in the Yippies, was another hero of the '60s. I did several long interviews with him that I hope will be on the site soon.
John Cipollina's site - the great guitarist for Quicksilver Messenger Service and other bands.
