ISFDB Top 100 Novels - Popular List
All novels which have been nominated for an award are scored based on the number of award wins and nominations. The results are then sorted. This is not an attempt to list the best works in theshow more genre, just those which won the most awards. Since the proliferation of genre-related awards is a fairly recent phenomenon, these lists tend to favor more recent works.
The Popular List puts extra emphasis on those awards which are decided by popular vote. It attempts to construct a list which might appeal to a younger audience. It assigns an additional penalty to older works for being "dated".
Note that this version of the list hasn't been updated since 2005.
