To organize a report on Saul Bellow, you might first present the major biographical themes, and then  move on to short story analysis. The major themes you might want to address are the position of Jews in North America at the time when Bellow was growing up and the nature of the Jewish intellectual milieu in Chicago and New York City. Many of his stories have protagonists who are aspiring young writers or intellectuals. Often they have certain flaws or insecurities and need to decide between artistic integrity and success. Often also there is tension between their roles as artists and academic. All of these issues are ones Bellow himself experienced.
