Dozois edited #6-10 of this series for publisher E.P. Dutton; this series is not the same as Dozois's later series for Bluejay/St.Martins - note that the two series have different titles. "Best Science Fiction Stories of the Year: Sixth Annual Collection" (Dutton) is an entirely different book (with entirely different contents) from "The Year's Best Science Fiction: Sixth Annual Collection" (St. Martin's).
