Malcolm is the founder of Heyday Books, established in 1974. The mission of Heyday Books is to deepen people’s appreciation and understanding of California’s cultural, natural, historic, literary, and artistic resources. Malcolm’s vision has led the press to be especially active in publishing works by and about the California Indian community. Heyday has published more than thirty books on California Indians and since 1987 has been distributing News from Native California, a quarterly magazine devoted to California Indian culture and history. Many of the existing tribes indigenous to the state of California were nearly wiped out, due to disease, enslavement, and institutionalized genocide. In his role as publisher, Malcolm has supported the revitalization of Native language, dance, basketweaving, storytelling, and religious practice. He is the author of four books, the best known of them being The Ohlone Way: Indian Life in the San Francisco-Monterey Bay Area.
