The Library of the Sierra Club based in San Francisco makes available at remarkably good prices copies of photos of John Muir (as I recall, they have at least one "field" shot and a couple of "portraits" (one "young" and one "old" as I remember). They also have available a selection on Ansel Adams prints -- all proceeds from these sales of photos benefit the SC's Colby Library... Sorry I don't have the exact info (I'm far away from my desk in SF) but call the Sierra Club and ask for the Library. They're in SF (area code 415) -- they also have an internet address: [log in to unmask] Tom Moritz California Academy of Sciences (from IUCN, Gland, Switzerland)
