The collection centres on Robert Dawson’s 1832 Reform Act plan of Coleraine and Taylor and Skinner’s 1778 road strips showing the town on routes from Dublin and Dungiven towards Coleraine and Portrush. Broader local coverage is supplied by John Bartholomew and Edward Stanford maps of the north Antrim coast, Portrush and the Giant’s Causeway, on which Coleraine is specifically shown.
