This joint CODEXMEXICO / Stanford University Library / CODEXAustralia event includes an exhibition, “The Book as Art,” and an accompanying two days (April 19 and 20) of free public programming at the Mexican Cultural Institute in Washington D.C. The exhibit itself opened on March 22 and will continue until June 15. Look here for a description and instructions on how to gain admission.
The Friday April 19th symposium is described here. On Saturday April 20th there will be an opportunity to view the exhibition and to talk with book artists and printers. California artist/printers and local printers and guests will display their work. My hunch is that you need to apply for admission to this, too, but I didn’t see specific instructions.
