Photographic archives are collections of photographs that are preserved for historical, cultural, or artistic purposes. These archives can include images from various sources, such as museums, libraries, or private collections. They serve as valuable resources for researchers, historians, and the general public, providing insights into different time periods, events, and communities. In addition to physical photographs, photographic archives may also contain digital images and metadata that describe the content, context, and significance of each photo. Many archives focus on specific themes, such as documentary photography, photojournalism, or the works of particular photographers, making them essential for studying visual history.
