On June 11, 2011, Triple Canopy and Printed Matter, Inc. presented Volume Number, a discussion of the past, present, and future of artists' publications. The conversation, recorded live at Dia:Chelsea, took as its starting point Gwen Allen's recent book Artists' Magazines: An Alternative Space for Art (MIT Press), which surveys American and European artists' publications from the 1960s to the 1980s. In this recording, Allen gives a brief presentation of this history, followed by a discussion of its relationship with a variety of contemporary publishing projects, from multimedia journals to generative archives to e-books. Participants include Paul Chan, Angie Keefer, Matt Keegan, and David Platzker, with Triple Canopy's Colby Chamberlain moderating.
