Permeable Press was a San Francisco-based literary publishing company founded in 1990 by Brian Charles Clark.[1][2] A "micropress" operating on less than U.S.$100,000 per year, Permeable published a number of trade paperback books, chapbooks, and the literary magazines Puck, Shock Waves, Q-Zine, Naked Review, and Xerotic Ephemera in the early and mid-1990s. Clark sold Permeable Press to Cambrian Publications in 1997.
