What happens when collecting becomes more than a hobby? A new series of short documentary films profiles four L.A. as Subject collectors who have obsessively focused on a narrow slice of Southern California history. Produced by the USC Libraries with generous support from Cal Humanities, Monomania L.A. is directed by Joris Debeij and hosted by David Kipen, who also serves as humanities advisor. The first three films were introduced at the October 25 Archives Bazaar (the fourth is currently in production) and the entire series will air later this year on public television station KCET. In the meantime, you can watch the videos online on the L.A. as Subject website.
