Jed Perl has a new book out about art in New York between the 1940s and 70s. “Through the book’s pages pour artists, critics, dealers, museum curators, museum-goers and the views Perl has intently constructed of them, drawing on archival materials, interviews and the old books and art catalogs he’s collected over the years. Most important, perhaps, are his own responses to art, people and institutions. The book — its full title is “New Art City: Manhattan at Mid-Century” — is essentially a book of ideas, a critic’s analytical meditation on how and why he thinks cultural history evolved as it did.”
