Since the advent of Pop art in the late 1950s, artists have been tasked with contending with its legacy and implications. Scholars and curators are now looking at the movement with a similar sense of urgency.

This month, Yale University Press is due to publish the art historian Thomas Crow’s book "The Long March of Pop: Art, Music and Design 1930-95," which examines the place of artists like Andy Warhol and Roy Lichtenstein within the wider web of 20th-century American and international culture.
