Notice: Appointments are required for entry into Library facilities, and everyone must follow the health and safety protocols established by the Library, in consultation with public health professionals (Most of these protocols are mandatory, regardless of vaccination status). Library users do not need to make an appointment to obtain or renew a Reader Card. However, users must obtain a time-ticketed pass or reading room appointment (if applicable) to come onsite to complete their reader card registration. Online resources and reference services, such as Ask a Librarian, will continue to be available during this time. For additional instructions, see: loc.gov/about/pandemic-information/for-researchers

The center of any great research library is its book collection. At the Library of Congress, the General Collections, comprised of approximately 23 million volumes, is the bedrock on which the institution is based. The Collections Access, Loan and Management Division (CALM) is responsible for maintaining and serving the General Collections, while ensuring, through appropriate security and preservation measures, that the collection will be available for future generations.
