Say what you will about librarians, they keep their promises and make good on their debts. So when the San Francisco Public Library (SFPL) lost a Superbowl bet with the Enoch Pratt Free Library of Baltimore, MD, SFPL Librarian Luis Herrera wasted no time keeping his end of the bargain: he recited Edgar Allan Poe’s "The Raven" in the atrium of the SFPL Main Library wearing a Ravens jersey, and posted the results on YouTube. (Or perhaps he just wanted to get it over with.) Herrera chose a jersey bearing the number 52, in honor of linebacker Ray Lewis, who announced his forthcoming retirement just before the playoffs. Had San Francisco trounced Baltimore, Pratt Library CEO Carla Hayden would have had to recite George Sterling’s "The Cool, Grey City of Love" in the Central Library Main Hall wearing a 49ers jersey.
