Check it out - the Athenaeum is running a bicentennial lecture series, free and open to the public. They have a "fridge list" showing lectures throughout the spring on library topics such as copyright (Feb 22), preservation (Mar 15), the cultural influence of libraries (Apr 26), censorship (May 10), and the organization of knowledge (May 17). All Thursdays, and all at 6pm. They also have an amazing collection of Webcasts.
