I might be open to editing this question to something like the following, then reopening:
What awards specifically track SF books and movies? How can I find lists of works that have received these awards?
Unlike our garden variety list-of-works question, the list is somewhat manageable and the criteria for inclusion are mostly clear. Still, the list is very long, longer than I'd imagined, and that's a bad sign.
Asking for sites that list awards is too far removed. Stack Exchange is not a repository of pointers, it's a repository of knowledge.
I don't feel very strongly about this.
A wiki would be the ideal format, really.

The awards tag has no wiki summary, can you help us create it?
