Carl Loeffler is Director of La Mamelle, Inc., an artists’ space founded in San Francisco in 1975. The primary activity of La Mamelle is art publishing in a variety of formats—books, magazines, video, audio, microfiche, and rubber stamps. Loeffler has been the guiding force behind La Mamelle’s extensive gathering and dissemination of information. He is the editor of Performance Anthology, a Source Book for a Decade of California Performance (1980), an invaluable addition to the very limited body of literature on performance.
