Timothy Leary RAW correspondence at the New York Public Library

The official opening of the Timothy Leary archives at the New York Public Library naturally leaves me curious about the correspondence between Leary and Robert Anton Wilson that might be housed there. A Twitter exchange:

@jacksontom No idea, but I imagine it must have some.

@TimothyLeary8 @jacksontom It's been 8 years since I looked in that archive so I cant say exactly what, but I'm certain there's some, Tom.
