Yorkshire and the North East
This is the area from the Humber estuary to the Scottish border, mostly east of the Pennines although the Yorkshire Dales to some degree cross to the west of the Pennines abutting Lancashire and Cumbria. The old counties of Northumberland and Durham as well as all the "Ridings" of Yorkshire are covered. Today that means South, West, East and North Yorkshire plus Durham, Tyne & Wear and Northumberland. Books relating to Hadrian's Wall are included here; some of these will also be categorised under the North West as the wall crosses from the North Sea to the Solway.
