* Leicestershire 25-inch map 33, 1 (1884 survey) and 43/70 NE and NW (1959–67). The amount of information about such sites given on large-scale O.S. maps varies, for detailed plans of deserted villages in Yorkshire E.R. are included, albeit on a rather small scale, on the 1st edition of the O.S. 6-inch maps of the county (1854–6). Thus, plans of Wharram Percy and Towthorpe appear on sheet 143, Cottam and Cowlam on sheet 144, and East Lilling (N.R.) on sheet 141. These details were included on the 1st edition of the O.S. 25-inch maps of the same area published 30 years later (1888–93). On the second edition of the 25-inch maps (1910–11) less information appears, as the representation of the earthworks is more conventionalized (for East Lilling alone, there is rather more detail). The earthworks are not shown in current editions of the large-scale maps.
