Through a series of short films and articles, Monomania L.A. profiles five L.A. as Subject collectors who have turned a monomaniacal obsession with a particular aspect of Southern California history into a public resource. These collectors have documented disparate subjects -- the California orange, sci-fi reading circles, political graphics, a Mexican rancho, African American photographers--but their stories share one thing in common: a passion for history that has enriched our understanding of Southern California's past.
