The first rule of Classification Club is -- you do not talk about Classification Club. The second rule of Classification Club is -- you DO NOT talk about Classification Club. The third rule of Classification Club is -- if in doubt, prefer 121.5. The fourth rule of Classification Club is -- the longer the number, the smaller the spine. That's our favorite, the fourth rule (a.k.a. Gorman's Third Law of Librarianship). Because everyone loves immensely long Dewey numbers. It's Friday, and it's only too clear that what the world needs today is another unfeasibly lengthy Dewey number. So we've got one for you. It's 791.436526230975091734, which is the number we mapped the other week to the Library of Congress subject heading "Rednecks in motion pictures." What's that? You want an even huger Dewey number? You're addicted. Can anyone help?
