what's your absolute favorite dewey decimal number. with as many significant figures as possible
(mine's 741 and the 520s)
That's a toughie. I'm rather fond of the 590s (animals), especially 594 (molluscs; snails, octopuses, etc.), 595 (arthropods; bugs), and 599 (mammals). A lot of posts are filed there. 394 (customs/holidays) and 398 (myths/folklore) are also really fun to read through. I'm a skeptic, I don't believe in magic, but 133 (parapsychology/the occult) might be my favorite just because it makes me feel like the protagonist in an old movie, walking into the library to research whatever horror is secretly afflicting my small town. Rosemary Woodhouse would have found 133.4 (demonology and witchcraft) quite useful.
