For centuries, dictionaries were works of almost superhuman endurance produced by people who devoted themselves for years, even decades, to the wearisome labor of corralling, recording, and defining the vocabulary of a language. Educators and authors Bryan A. Garner and Jack Lynch share the stories behind these great works of scholarship and the people who produced them, including towering figures of English lexicography such as Samuel Johnson, Noah Webster, and the Oxford English Dictionary’s James Murray, as well as more obscure dictionary makers whose achievements are no less fascinating.
