There will hopefully be tabs for the Hugo, Nebula, Sturgeon, Otherwise, WFA, BSFS, BFS, and other short fiction award nominees when the new website goes live.

Until then, I've been using ISFDB to pull the nominee lists for various short fiction awards:

Hugo Novelette Finalists
http://www.isfdb.org/cgi-bin/award_category.cgi?262+1
Hugo Short Story Finalists
http://www.isfdb.org/cgi-bin/award_category.cgi?274+1

Nebula Novelette Finalists
http://www.isfdb.org/cgi-bin/award_category.cgi?414+1
Nebula Short Story Finalists
http://www.isfdb.org/cgi-bin/award_category.cgi?418+1

etc., etc. 

and cross-referencing with our list by category for specific years (bearing in mind that the Award Year is Publication Year+1)

While we still have a bit of catching-up to do, we've got most of the short fiction nominees in the WWEnd database.
