Appointments are optional, but encouraged. To help us better serve you, request a research appointment to ensure collection material is accessible during your visit at the Library. 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 the Office of the Attending Physician of the U.S. Capitol. For additional instructions, see the Researcher Scheduling page.
Unique in their scope and richness, the picture collections number more than 16 million images. These include photographs, historical prints, posters, cartoons, documentary drawings, fine prints, and architectural and engineering designs. While international in scope, the collections are particularly strong in materials documenting the history of the United States and the lives, interests, and achievements of the American people.
