The Infogroup Historical Business Backfile, 1997-2016, is available at Harvard.
InfoGroup’s Historical Business Backfile consists of geo-coded records of US businesses and other organizations that contain basic information on each entity, such as: contact information, industry description, annual revenues, number of employees, year established, and other data. Each annual file consists of a “snapshot” of InfoGroup’s data as of the last day of each year, creating a time series of data 1997-2016. The 2016 data file covers approximately 20 million business records representing all industries.
Harvard University users may request access through the Infogroup Dataverse record.
