One thing I have always done, when I come across a book that I really liked, is to buy everything I can find by that author, and seldom have I been disappointed. I think the first author I did that with was John Steinbeck. Known for only a few of his books, Of Mice and Men, The Grapes of Wrath, Cannery Row, The Pearl, and East of Eden, he has written more than thirty books, and some of the others are every bit as good, I think. When I was in high school, I bought every John Steinbeck book I could find, and bought others many years later, when the Internet allowed me to access books that I couldn't find otherwise. I've done that with W.P. Kinsella, Gunter Grass, Erskine Caldwell, Kurt Vonnegut, Mark Twain, F. Scott Fitzgerald, William Faulkner, John Updike, Orson Scott Card, John Irving, Robert Penn Warren, Philip Roth. Lois Lowry, Philip K. Dick, Richard Brautigan and Cathie Pelletier, to name a few. I would include Ken Kesey and J.D. Salinger as well, but they didn't write very many. I do think that Kesey's Sometimes a Great Notion was a better book than his better known One Flew Over the Cuckoo's Nest. There are others too, but I'm not at home so I can't refer to my library. These are the ones that come to mind.
