John Steinbeck banned the book from the county's publicly funded schools and libraries. It was burned in Salinas on two different occasions. In 2003, a school board in Mississippi banned it on the grounds of profanity. According to the American Library Association Steinbeck was one of the ten most frequently banned authors from 1990 to 2004, with "Of Mice and Men" ranking sixth out of 100 such books in the United States. The award of the 1962 Nobel Prize for Literature to Steinbeck was controversial in the United States. The award citation lauded Steinbeck "for his realistic and imaginative writings, combining as
John Steinbeck asocial individuals who, in their wild revels, are almost caricatures of King Arthur's Knights of the Round Table. It has been said that in the United States this book came as a welcome antidote to the gloom of the then prevailing depression." "Tortilla Flat" was adapted as a 1942 film of the same name, starring Spencer Tracy, Hedy Lamarr and John Garfield, a friend of Steinbeck. With some of the proceeds, he built a summer ranch-home in Los Gatos. Steinbeck began to write a series of "California novels" and Dust Bowl fiction, set among common people during the Great Depression.
