The Brautigan Library in suburban Boston may be the only library conjured into existence by a 1960s counterculture novel. It is almost certainly the only library to consist entirely of unpublished work: “From 1990 to 1996, the Brautigan Library accepted manuscripts from all over the world, as long as the authors paid binding costs.” But like all good ’60s icons, the Brautigan collection looks likely to spend its mature years in Northern California – specifically, in the Presidio Branch of the San Francisco Public Library.
