archival materials
Archival materials are documents and records that are preserved for their historical, legal, or cultural significance. These materials can include letters, photographs, official documents, and audio-visual recordings. They are often stored in archives, which are specialized facilities designed to protect and maintain these items for future research and reference.
These materials serve as important resources for historians, researchers, and the public, providing insights into past events and societal changes. Examples of archival materials include government records, personal diaries, and historical newspapers. They help to document the history of individuals, organizations, and communities.
