An archivist is a professional who assesses, collects, organizes, preserves, maintains control over, an provides access to information determined to have long-term value. The information maintained by an archivist can be any form of media (photographs, video or sound recordings, letters, documents, electronic records, etc.). As Richard Pearce-Moses wrote, "Archivists keep records that have enduring value as reliable memories of the past, and they help people find and understand the information they need in those records."
