Do you want to know what businesses were in your town 100 years ago? Are you interested in the financial strength of your grandparents’ shop? R.G. Dun & Company, now known as Dun & Bradstreet, was a credit reporting agency that provided ratings on an enterprise’s financial strength and ability to pay back debts.

Their Reference Book was published quarterly and covered the merchants, manufacturers, and traders in the United States and Canada, from big businesses to local mom-and-pop shops.

The Library of Congress digitized volumes from 1900 to 1924 earlier this year and made them freely accessible on our website. Business Reference and Research Specialists will show you how you might use this publication to explore local business history or trace a family business for genealogy research.
