During the past four decades, the accessibility of videotape, along with that of 8- and 16-millimeter film, has revolutionized artistic production, and moving-image technologies ranging from the filmic to the digital have attained mainstream status. This exciting publication, the first devoted exclusively to the Art Institute's expanding collection of film and video, records the emergence of a new medium and captures the quickly evolving state of the art.   The book explores more than eighty works at the Art Institute, from those by early pioneers like Bruce Nauman and Nam June Paik to others by such recent practitioners as Doug Aitken, Sharon Lockhart, and Steve McQueen. The book showcases works by Tacita Dean, Rineke Dijkstra, Nan Goldin, Jenny Holzer, Pierre Huyghe, Isaac Julien, William Kentridge, Gordon Matta-Clark, George Segal, Richard Serra, Bill Viola, and many more.
