Scofield presented a list of the most frequently selected books. Scofield's description is very revealing: "An examination of these titles shows that the students have selected far better literature than we might expect from some of the assertions we hear about the habits of high-school pupils" (p. 545).
Even one hundred years ago, people were concerned that young people were not reading "good" books. Scolding teenagers is nothing new (Krashen, 2011).
Among the top ten: Huckleberry Finn, Tom Sawyer, The Call of the Wild, The Last of the Mohicans, Kidnapped.
