This is a collection of three types of slide rule records: Archives, Cross References, and Lists from various sources on the internet.

Archive: A complete list with a large amount of data with photos for each slide rule.
Cross Reference: A complete list with a large amount of data for each slide rule but no photos.
List: A complete list with a limited amount of data for each rule.

Complete means the record contains all known rules of that maker, as obtained from makers' catalogs by diligent researchers.
