To mark the occasion of Shakespeare's 450th birthday, scholar James Shapiro discusses his new anthology, Shakespeare in America, which, as he writes in the introduction, is also "a history of America itself, not the straightforward narrative found in textbooks, but rather one that runs parallel to the conventional story of the nation, a more sharp-edged one expressed through two-and-a-half centuries of essays, parodies, burlesques, poems, speeches, short stories, letters, musicals, novels, reviews, films, and staged performances. These works, by some of the most creative minds in America, explore the cultural fault-lines that have always existed just below the surface of our national conversations."
