Samuel Pepys's Diary was first published in abbreviated form in 1825. However, not until the publication of the Latham and Matthews edition was the Diary presented in its complete form, with a newly transcribed text and the benefit of a systematic commentary. The text of the Diary is in nine volumes, followed by this Companion and an Index.
The Companion has been compiled and edited by Robert Latham, with specialist contributions from other scholars. Over 1,700 entries, alphabetically arranged, fill in the background details about the people and places mentioned in the Diary. There are longer articles on a wide range of subjects of particular relevance to Pepys and his period. In addition, many aspects of social history are covered in articles on, for example, dress, food, drink, taverns and travel. The book is completed by an extensive glossary, genealogical tables, a chronology and maps.
