This list will be mostly *new* SFF but FWIW there’s a vigorous tradition of writing—and critiquing—diversity in SFF.
Samuel Delany’s 1977 review of the first Star Wars is a landmark here: in it he says, of SFF films, “the variety of human types should be as fascinating and luminous in itself as the variety of color in the set designer’s paint box. Not to make use of that variety… seems an imaginative failure.”
I hope my list is in that spirit. #bookstodon
