Do other SF/F/H works utilize references to other literature? Yes, some of them. For example, The Martian Chronicles by Ray Bradbury has a section "Usher II" which is very reminiscent of Edgar Allan Poe's "The Cask of Amontillado", and of course, there's Poe's "The Fall of the House of Usher". Another example is To Say Nothing of the Dog by Connie Willis--an hommage to Three Men in a Boat (To Say Nothing of the Dog) by Jerome K. Jerome from 1889!
Can you think of other examples of literary references in SF/F/H? Do think they're a good idea, or a short cut? If the former, consider sending us a story with a literary reference. :)
