In 2009, Scribner published a new, controversial, version of Ernest Hemingway's A Moveable Feast, edited by his grandson, Seán Hemingway. (The original version, which is the one we are reading in class, was published by his fourth wife after Hemingway's suicide in 1961.) Some of the controversy is over the portrayals of Hadley, his first wife, and Pauline, his second wife, who appears, unnamed, at the very end of the book. But the new edition is not necessarily more "definitive" than the old edition and many Hemingway scholars do not think it is more authentic, though it does include some new material.
Here is an article about the new edition and the controversy in The New York Times and another in The Globe and Mail.
Hemingway's friend and biographer, A.E. Hotchner, wrote this disapproving op-ed when the new edition came out. Scholars have expressed doubt with his version of events.
And finally, here's a response from Seán Hemingway on Book TV.
