Editors Amy Fischer and Liz Holum Johnson open doorways to the often closed realm of corporate archives in this publication from the Business Archives Section of the Society of American Archivists. The Directory of Corporate Archives in the United States and Canada, an ongoing effort, details the nature, location, and accessibility of historical business records for corporate archivists and researchers. Over 200 entries from Anheuser-Busch and Blockbuster Entertainment to the William Wrigley Jr. Co. are listed by company name, geographical location, or name of archivist, and complete contact information, conditions of access, and physical description of materials are provided when available.
