The introduction discusses the history and assessment of the county; the county boundary; the Hundreds, their rubrication, order, composition, and revised name-forms; the state of the manuscript for the county; places surveyed in other counties; boroughs, claims and illegalities; related or 'satellite' texts (see Appendix); the editorial history of earlier versions of the notes, and the current state of the revision. Some material in this introduction derives from the original printed edition published by Phillimore (1982) and edited by Caroline and Frank Thorn.
