Even if you don't, you might want to think about going beyond the bestseller list and choosing some things from other decades.
I have decided to do 12 books from 12 consecutive decades, working back from our present 2000s (otherwise named by my partner as the "ought naughts" as in "these Bush years ought naught to have happened") to the 1890s.
So, here is my list (bold titles have been finished):
1890s: Lourdes by Emile Zola
1900s: The Golden Bowl by Henry James
1910s: The Rainbow by D.H. Lawrence - 5/23/07
1920s: Point Counter Point by Aldous Huxley - 7/16/07
1930s: The Big Money by John Dos Passos (3rd in his USA trilogy) - 5/30/07
1940s: Dirty Snow by Georges Simenon - 5/20/07
1950s: Mountolive by Lawrence Durrell (3rd in his Alexandria Quartet) - 2/27/07
1960s: The Mandelbaum Gate by Muriel Spark - 7/1/07
1970s: A Word Child by Iris Murdoch - 6/4/07
1980s: In the City of Fear by Ward Just - 11/10/07
