Debrett

Debrett's is a British publisher and authority on aristocracy and social etiquette. The name is most widely associated with Debrett's Peerage & Baronetage, a long-running annual reference work that lists the titled families of the United Kingdom, with genealogies and biographical notes. The brand also publishes guides on etiquette and social protocol, as well as directories of notable people.

Debrett's was established in London in 1769 by John Debrett as a publisher of peerage information. Over the centuries the works expanded to cover England, Scotland, Ireland, and eventually the United Kingdom as a whole. The brand became a standard reference for those needing information on noble titles and lineages.

Debrett's Peerage & Baronetage remains the flagship title, with updated editions detailing current title holders, family lineages, and heraldic information. In addition, Debrett's Correct Form provides guidance on forms of address and proper etiquette. Debrett's People of Today profiles notable British citizens across various fields, while online resources extend the brand to digital reference and etiquette guidance.

Usage and influence: The publications have historically served journalists, genealogists, researchers, and institutions requiring authoritative information on class and heraldry, while etiquette guides have informed social formalities and professional conduct.

Modern status: Debrett's continues to publish and maintain an online presence, combining traditional reference works with contemporary guidance on manners, dress, and social norms.
