There is actually a free online course on not only Ernest Hemingway but also William Faulkner and F. Scott Ftzgerald. I know exciting right! The course is offered by Yale University and it is titled 246: Hemingway, Fitzgerald, Faulkner. The Professor is Wai Chee Dimock and the course consists of 25 lectures involving three of the greatest authors of our time. Enjoy and let me know what you think.
Here is a second link that I found interesting on a story by Professor Wai Chee Dimock on Ernest Hemingway during his Paris years as well as a few other books.
