R.G. Dun & Co. / Dun & Bradstreet Collections

Founded in 1841 by Lewis Tappan, the Mercantile Agency-later known as R.G. Dun & Company-was the first successful commercial reporting agency in America. The company pioneered the new industry of credit reporting, an important tool in the development of American commerce during the 19th century. Dun & Bradstreet resulted from the 1933 merger of R. G. Dun & Company and its chief competitor, J. M. Bradstreet & Company. It continued to be an innovator in business information through the 20th century and beyond.

Baker Library holds two separate collections relating to these companies that provide contextual information about the development of credit reporting in the United States. The first, the R. G. Dun & Company Credit Report Volumes, consists of 2,580 volumes of handwritten credit reports collected by the company from 1841 to the early 1890s. The second collection, the Dun & Bradstreet Corporation Records, details the growth of the company and its predecessors from the 1840s to the late 20th century

Finding Resources: R. G. Dun & Company Credit Report Volumes

Use the guide to the R. G. Dun & Company Credit Report Volumes to identify volumes relevant to your research project. Researchers need to know the state/territory and the county of interest, as well as the names of individuals or businesses. The credit report volumes are arranged geographically by state or territory. Each state or territory is then subdivided alphabetically by county and/or city. Most include alphabetical name indices that need to be consulted first, as they direct the user to the volume and page where the credit report is recorded. The volumes for smaller states or territories sometimes contain multiple counties within a single volume.

The R.G. Dun & Co Credit Report volumes use a complex system of abbreviations. In order to help you maximize your research time, we have created a list of the more Common Abbreviations used in the R.G. Dun & Company Credit Report Volumes.
