The Library of Congress (LOC) has acquired the archive of Bob Adelman, a photographer who helped document the Civil Rights Movement of the 1960s and continued to be active in social justice issues in the decades that followed, until his death in 2016. The trove, gifted by an anonymous donor, comprises 575,000 images, negatives, and slides, including 50,000 prints.
The Library of Congress (“LOC”) is the research library that officially serves the United States Congress and is the de facto national library of the United States. It is the oldest federal cultural institution in the United States. The Library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains the Packard Campus in Culpeper, Virginia, which houses the National Audio-Visual Conservation Center.
The Library of Congress claims to be the largest library in the world. Its “collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 450 languages. Two-thirds of the books it acquires each year are in languages other than English.” (Wikipedia).
