Hart's Rules is the oldest continuously updated style guide in the English language, providing advice on topics such as punctuation, citation, and typography. Printer and biographer Horace Hart first issued the work in 1893 for the compositors and readers of Oxford University Press (OUP). It has evolved through multiple editions to become one of the most influential works of its kind.
