...the War in Darfur, Hebrew Printing in America, Justification (in a theological sense), Richard Nixon, Scientology, Marvel comics' Daredevil, Opus Dei, Harold Pinter, Irish Railways, Classical Guitar, the Duwamish tribe of Washington state, and Yellowstone National Park.
What do these things have in common?
There are bibliographies of them listed on Wikipedia.
There are, however, subcategories of bibliographies about Spiderman, the X-Men, Cricket Books & Magazines and Science Publications.

Wikipedia is weird and wonderful.
Disclaimer #1: I can vouch for the quality of none of these bibliographies.
Disclaimer #2: Wikipedia changes constantly, so some of these -- or even the whole !@#$% category page -- may be gone if you actually check.
