There are various competitions that attempt to find the best science fiction, fantasy and horror of each year, and I've collated the winners and nominees from what seems to be the major awards in a series of posts (see the very bottom for links to all of them). The requirement for inclusion is that the award ceremony occurs in the current year (as listed in the title), so the post will be updated as they are announced throughout the year.
The awards considered are: Arthur C. Clarke, Bram Stoker, British Fantasy, BSFA, Compton Crook, Dragon, Eugie, Hugo/Lodestar, John W. Campbell Memorial, Lambda, Locus, Nebula/Andre Norton, Otherwise, Philip K. Dick, Prometheus, Shirley Jackson, Sturgeon and World Fantasy.
This is the post for the novella category.
There's two options for viewing them. The first is my ranking, which is wildly subjective and limited to the ones I've read. The second is based on the "score" of each work, with a nomination giving 1 point, and a win giving 1.5 points. Otherwise it's ordered by title. Click the button to view.
