Here's an interesting discussion point from the Guardian blog. Many authors are known for one book - but write better ones that aren't as popular or as acclaimed.
Not sure I can comment on any of the authors mentioned here, but it is a cute parlour game. The Dickens I loved the best was Dombey and Son, but it often gets overlooked on the best of lists. Similarly, Tender is the Night, hardly unknown mind you, was so much better than The Great Gatsby.
Of course there is no rule to this. Often writers become known for one book simply because that book is very good - and their other work not quite of the same level. I wouldn't complain too much. Better to write one great novel and ten not so good ones than not to write at all.
