This week I've been mainly reading, no. 318.
Alice Goldfarb Marquis' Marcel Duchamp: The Bachelor Stripped Bare (2002) will be of great help to anyone trying to make sense of Duchamp's contentious influence on contemporary art. Mixing analysis & biography Marquis does an excellent job of both situating the artist & exploring the driving interests behind his life & work. Largely sympathetic it is however not uncritical & thus is a great place to start figuring out Duchamp.
