Coming up at the British Library and running from November 24 to March 4, an exhibition called “London: A Life in Maps”: “Maps, views, letters, and ephemera from the British Library collections, show the city’s transformation from a Roman outpost to the huge, heaving metropolis of today — and look to the Olympic and post-Olympic future.” Free admission; there’s also a companion book by Peter Whitfield coming out.
