We request that all visitors schedule an appointment so that we may better satisfy their research needs. This is especially important as some collections are stored off site and can take up to 72 hours to retrieve. We will close for Christmas Break at 12 on Friday, December 20, and re-open at 9am on Monday, January 6, 2014.
Please call 202-319-5065 to schedule an appointment.
