For Researchers

Library of Congress Welcomes the Return of Researchers with Scheduled Appointments

The Library of Congress is gradually reopening its doors with enhanced procedures and requirements that prioritize the health and safety of Library employees and users. We’re excited to welcome you at one of our 16 reading rooms, and look forward to making your visit a success. We ask that researchers interested in using the Reading Rooms for research do the following:

  • Check the information below for the current public hours of the reading room you are interested in.
  • Schedule a research appointment by calling the phone number of the reading room you need to do research in, or by using our online Ask-a-Librarian service. Researchers are encouraged to make appointments at least 24 hours in advance. Library staff will confirm the date and time of your scheduled appointment.
  • Get a new reader card, if you don’t have one, or renew your reader card, if yours is expired. A Library of Congress Reader Card is required to use the reading rooms and pre-registration should be completed online.
  • Read the Library's ‘Know Before You Go’ Checklist before your scheduled visit.

During your time at the Library, you must:

  • Bring proof of your appointment for entry into the Library’s buildings
  • Wear a mask: Everyone must wear a barrier mask or cloth face covering that fully covers the nose and mouth and fits snugly against the sides of the face when arriving at Library buildings and while they are inside the Library, including in bathrooms.
  • Follow social distancing policies: Pay attention to posted signs throughout the building to ensure physical distancing and other health precautions.
  • Comply with all health procedures: At the time an appointment is made, health screening requirements will be provided, and temperature checks and screening questions must be completed before entering the building.
