In addition to the names in the present county, this volume also includes those of parishes which have been, since 1965, within the boundaries of Greater London (e.g., Barking, Ilford, Romford, East and West Ham, Walthamstow, and Leyton). No further changes were made in 1974. The editor noted in the Introduction that No county bears so strongly as Essex the imprint of the Norman Conquest, adding that the map of Essex is dotted with names that preserve - often in strange disguise - names of French towns and French families. In the seventy-five pages devoted to field-names the editor was able to identify and explain a number of previously unrecorded forms. Among the field-name terms selected for separate indexing are brank, cammock, hoppet, queach, watership and wynd. An end-pocket contains a county map and eight distribution maps (some locating individual elements such as wic or (ge)hoeg, others marking related groups).
