Locus has published a list of 2006 Books by Editor, but the coverage is spotty. The list seems to be missing Jim Baen, Toni Weiskopf and any other Baen Books editors; Jennifer Brehl, Diana Gill, and any other Harper editors; any Pocket books editors; any Dragonlance, etc. editors; any DAW editors; any Warner editors; and probably more.

UPDTAE: Mark Kelly has updated his list to include info on many more editors.
