Rich Horton (ed)'s "The Year's Best Science Fiction & Fantasy, 2012" (anthology)

Horton posted the ToC a couple of days back. 29 short stories picked by the editor from among those first published during 2011. I think it's several months before the book is actually available in a store.

Where I'm aware of online availability of a story, I include the link too. Links on author, publisher, or editor fetches more matching fiction.
