The British Library has a few maps in its collection, and it is an institution that is well-positioned to create an exhibition with the title "Magnificent Maps: Power, Propaganda and Art". This digital exhibit is meant to complement an in situ exhibit that explores these main themes through 80 different maps. On this site, visitors can look over four of these marvelous maps in exquisite detail, and also watch and listen as the exhibit's curators talk about each work. The maps include the Psalter World Map from 1625, which is most likely a copy of the lost map which decorated King Henry III's bedchamber in Westminster Palace. "The Island" map shouldn't be missed either, as it satirizes "the London-centric view of the English capital and its commuter towns as independent from the rest of the country." The site is rounded out by a blog maintained by the curators, and it is worth a look.
