This carto-bibliography of over 1300 Devon manuscript maps published in two volumes contains details not only of the maps themselves, extracted from 30 separate repositories in addition to some in private hands, but also biographical information on the surveyors who made them, over a third of whom have not appeared in any national cartographic reference book. There is also an Introduction which explains the significance of these, mostly large-scale, Devonmaps and how they fit into the national cartographic picture. The detailed list of maps is arranged in alphabetical order of parish for ease of reference and there is a Personal Names index. There are coloured illustrations of some of the maps and the two volumes will be presented in a slipcase. The volumes will be an indispensable reference tool for all interested in the social history, the landscape and archaeology of Devon.
