I just love booklists! TIME magazine features a list of the top 100 novels published since 1923. The urge to compare one's bookaddled self against such a list is irresistible.
I scored 33 and a half (I left Atonement half-way through distracted by other books I had to read!) and feel significant amounts of bookguilt about the 66 and a half I need to make a start on.
Of course any list is subjective. This one is weighted towards American writing. There's an interesting discussion going where readers talk about the books that should be on the list.
