Originally published in 1920, this volume provides information on the historical background of place-names in County Durham and Northumberland. The text was compiled by Allen Mawer (1879–1942), who was instrumental in the foundation of the English Place-Name Society. Entries are listed in alphabetical order and vary in length, depending on historical interest or the complexity of their development. Notes are provided on elements found as the second part of place-names or used by themselves, and personal names found as the first element in place-names. Additionally, the text contains an introduction, bibliography and information relating to phonology. This is a fascinating volume that will be of value to anyone with an interest in British history and the development of toponymy.
