Appointments are optional, but encouraged. We recommend that researchers speak with reference staff to ensure collection material is accessible during their visit. To consult with a reference librarian, please call (202) 707-5639 or submit an Ask-a-Librarian query. If you'd like to book an appointment, please use our appointment reservation system.
The Library of Congress asks all visitors to follow our COVID-19 health screening protocols, which are based on guidance from the Centers for Disease Control and Prevention and the Office of the Attending Physician of the United States Congress.
