When I was 9, I spent a lot of time at a public library just down the street; I was already a theater nerd, and it had a well-stocked theater section. Not just books, but original cast albums for Broadway shows old and new. One day, an addition: The Music Man, about a salesman who was crazy about a girl named, as one song put it, "Marrrrrrrion, madam librarian."
Andrew Carnegie was once the richest man in the world. Coming as a dirt poor kid from Scotland to the U.S., by the 1880s he'd built an empire in steel — and then gave it all away: $60 million to fund a system of 1,689 public libraries across the country.
Carnegie donated $300,000 to build Washington, D.C.'s oldest library — a beautiful beaux arts building that dates back to 1903. Inscribed above the doorway are the words: Science, Poetry, History. The building was "dedicated to the diffusion of knowledge."
