I was a bit startled to see that, uploaded on the Library of Congress's YouTube Channel, is the Center for the Book presentation by Sara Paretsky that coincided with the winter 2007 Clues theme issue on her work. Yours truly shows up at the end.
(Also check out this LOC presentation by Washington Post Book World columnist Michael Dirda. Dirda is a big fan of, among others, John Dickson Carr, H. Rider Haggard, Georgette Heyer, and Philip K. Dick.)
