Users of the Library's research areas, including Computer Catalog Centers, and Copyright Office public service areas are each required to have a Reader Identification Card issued by the Library.
Cards are free and can be obtained by completing a registration process and presenting a valid driver's license, state-issued identification card, or passport. Researchers must be 16 and above years of age at time of registration.
Use this system to pre-register for your Library of Congress Reader Identification Card. In order to complete your registration and receive your card, you must come to the Library of Congress in person and present your valid form of identification at the Reader Registration Station located in the Madison Building, Room LM 140.
