The #LibraryOfCongress #classification manual is hilarious. TR717.3 is photography of machinery, special subjects. The three special subjects listed are airplanes, automobiles, and sex machines.
But the manual instructs that collections of photographs in certain fields be classed with those fields. That means all your books of photos of sex machines have to go in the sex machine section, while books about how to photograph sex machines go in TR717.3.S49.
