I'm doing workshops in June and August on Genre Writing. (You didn't know that? Where have you been?) I can of course run on about the various genres, their uses and meanings, from now until... quite some time from now. But I do like to give students a chance to hear it from other horses' mouths. I have good material on crime and romance, but you sci-fi, fantasy, horror and western writers out there: can you steer me to books or essays that discuss your genres?
