Archival sources can be manuscripts, documents, records (including electronic records), images, artifacts, recorded sound or moving images, or other materials. This guide includes resources and instructions for defining primary sources, developing archival research strategies, locating and citing archival materials, and understanding essential aspects of archival theory and practice.
An archive is "an organized collection of the noncurrent records of the activities of a business, government, organization, institution, or other corporate body, or the personal papers of one or more individuals, families, or groups, retained permanently (or for a designated or indeterminate period of time) by their originator or a successor for their permanent historical, informational, evidential, legal, administrative, or monetary value, usually in a repository managed and maintained by a trained archivist. Also refers to the office or organization responsible for appraising, selecting, preserving, and providing access to archival materials."
