have just had a quick look through his 60s letters.
so, HERE it is off-top.
on keeping CARBONS:
letter to Jon Webb / Dec 19, 1962:
"... And the other stuff, the older stuff has disappeared and I don't keep records and/or carbons so it's pretty much lost."
letter to J.W.Corrington / Dec 24, 1962: (only ONE week later!)
"... On the poems about Jane, I kept copies ..."
letter to John Martin / May 29, 1968:
"... yes would like to do another book with you - the new poems - will keep carbons of all the shit I write from now on. plus, there is plenty of back work."
on keeping NOTEBOOKS:
letter to Jim Roman / Jan 11, 1965:
"If I'd saved all my notebooks I wouldn't be able to move around this kitchen - or read them either."
