The National Library of Scotland has three collections of maps online: Maps of Scotland, 1560-1928; Pont's Map's of Scotland, ca. 1583 - 1596; and Military Maps of Scotland. Maps of Scotland contains 800 early maps -- including maps of the whole country, county maps, town plans, and sea charts -- while the Pont's Map's of Scotland contains 77 manuscript maps made by Timothy Pont. On the search screen, pull-down menus facilitate finding maps by geographic location, names of surveyors, map makers and engravers, or by keyword. Once found, viewers can zoom into a map, but decompressing the larger images can be a little slow. Lastly, the database contains close to 400 military maps primarily from the 18th century, with over half detailing four major fortifications: Edinburgh Castle, Fort Augustus, Fort George at Ardersier, and Fort William.
