This is a list of the 50 most significant science fiction/fantasy novels, 1953-2002, according to the Science Fiction Book Club. I'm not sure I agree with this list, but then a lot of the novels I consider more significant are likely outside the time-scope of this list, on the earlier side.
Bold the ones you've read, strike-out the ones you hated, italicize those you started but never finished and put an asterisk beside the ones you loved.
