The Delta Collection Is the Largest Collection of Historic Pornography in the World

The Delta collection was established to be kind of a holding space for obscene materials that were seized by federal agents. It also served as a database so that law enforcement could actually kind of catalog which types of literature should be considered pornography. For a long time it was secret and they didn't talk about it in public because it seems very morally problematic right given the various moral panics in US history. There was one guy at the Library of Congress who was super into this. We have to introduce you very briefly in a safer work way to a dude named Ralph Whittington. This guy is super into historical depictions of naughty bits.
