Every point is a coordinate printed in a gazetteer entry (“W. Long. 69. 48. N. Lat. 46. 55.”) — the world as the Britannica measured it, not as we do. Toggle editions to watch coverage grow. Verified misprints (SCARBOROUGH’s transposed latitude would put Yorkshire on the equator) are plotted at their true position, dashed, with the coordinate as printed in the popup.
