I'm stunnd to learn I have a folder in Allen Ginsberg's papers at Stanford. I don't recall writing to him.
I do remember a 1970 letter I wrote to Jean-Claude van Itallie abt my encounter with Ginsberg at the COSMEP conference in Buffalo. funny stuff.
I suspect I may have invitd him to contribute to the d.a. levy issue of The Serif that I editd in 1971. but if I did he never answerd.
