Anyway, apparently there is a Brautigan inspired library of unpublished books - see here .
I remember it being reported that Brautigan died in 1984 though not the circumstances - apparently he committed suicide and was a leaker (all together now 'take my hand, don't fear the leakers'). As one of the San Francisco 'beat' group his stuff is very much 'of its time', and at least one of the user reviews on Amazon says he is very sexist, which I remember thinking when I read some of his stuff. 'The Abortion An Historical Romance 1966' is the one I liked the most, though other things are more famous.
