I'm from Maryland and John Waters is my favorite famous hometown boy. (I’m reading his new hitchhiking memoir Carsick now.) I serendipitously met him once at a gallery in P-town and he was just as engaging one-on-one as he is in this video—a recent interview from the LIVE from the NYPL series.
Unsurprisingly, Waters is a great story-teller and in it, he talks about his book collection (think counter-culture and LGBT literature with punny titles) and name-checks our friends at Bolerium Books. He also discusses the problems institutions face when collecting material that is no longer "PC" or otherwise considered distasteful.
