Fitzgerald died before he could complete his fifth novel. His manuscript, which included extensive notes for the unwritten part of the novel's story, was completed by his friend, the literary critic Edmund Wilson. When Wilson published his finished version, titled "The Last Tycoon", in 1941, he included "The Great Gatsby" within the edition, sparking new interest and discussion. The novel gained further popularity during World War II, when it was selected to be part of the Armed Services Editions, books which were printed for American troops. Through an arrangement with the Red Cross, some novels were even sent to Japanese and German POW camps. By 1945, over 123,000 copies of "The Great Gatsby" had been distributed among American troops. In 1960, "New York Times" editorialist Arthur Mizener declared that it was "probably safe now to say that it is a classic of twentieth-century American fiction." Into the 21st century, millions of copies of "The Great Gatsby" and his other works have been sold, and "The Great Gatsby" is required reading in many high school and college classes.
