I have all my fiction sorted into period, then alphabetically, so Frankenstein is in the 19th c section. There are a few alarming titles in the early modern section, though I can't remember them off the top of my head. Le Guin was at head height until the latest re-arranging, and one of them is bright yellow, so I think it was that they were spotting.

When people notice my edition of Gone with the Wind, one of those books so thick that they got an entire (and lurid) film poster on the spine, I cheerfully shock them by telling them all about the mad lesbian subtext.
