Depending on usage, the word "archives" may be broadly defined in several ways but most often means records created or accumulated by one person, family, or organization and preserved because of their continuing value.

Suggested resources for starting a search for archival collections in databases:
Because archival collections are usually organized by creator and not subject, you'll usually have the best luck if you search for the records and papers of those specific people and organizations you've identified as associated with your topic.
