Museums of contemporary art are expanding and in crisis. They attract ever-larger audiences, architects constantly redesign them, and the growing number of artists is producing more massively than ever; at the same time museum funds are dwindling in the economic crisis and an overheated art market.The question of which art is to be collected is also becoming a more openly discussed topic in a globalized art world. How do curators meet these challenges? What opinion do the artists have of their relationship to the museum? How do practitioners navigate between ideas, ideals, and realities?This publication gathers together interviews with international artists, architects, and curators of the contemporary art world, such as John Baldessari, Ute Meta Bauer, Suzanne Cotter, Ulrich Obrist, Rem Koolhaas, among others.Their different answers bring visibility to the complexity of the topic, but also to the deep pleasure and intellectual stimulation museums provide, as well as to their relevance to culture today.The book is part of the Documents series, co-published with Les presses du réel and dedicated to critical writing.
