The Ethnobotany Library in Occidental, north of San Francisco, is our headquarters and a remarkable site where you may visit and handle real books, which are, in fact, made from plants and about plants and plant knowledge! Or the books are about mushrooms or human cultures that know nature, and much more. 1400+ volumes of fascinating writing. We have regular members-only events, and we host a unique Ethnobotany Festival & Symposium. (Next one will be in September, 2018.)
