Dun & Bradstreet has been a major publisher of business information from its earliest iteration back in 1841. Our collections cover complete runs of some publications, but the majority of titles are from the 1960s to 1990s. Titles like The Reference Book of American Business trace businesses from 1843 to 2006, while the currently published Who Owns Whom provides ownership information. Others, like the Million Dollar Directory, can be found within our electronic subscription databases. The company introduced the Data Universal Numbering System, or D-U-N-S, in 1963, a unique number that links a company to its Dun & Bradstreet credit report. DUNS Numbers are used by lenders, government agencies awarding contracts or grants and retailers registering business suppliers.
