Just a reminder about the marvellous Magnificent Maps exhibition running at the British Library St Pancras until 19 September 2010. If you haven't had a chance to visit it yet, do try to - it's free! The website supports the exhibition and in addition to visitor information it also has some great online features. These include interactive images of some historic maps including the Psalter world map and the Fra Mauro map with background information on their content and importance.
If you missed the recent BBC series The Beauty of Maps the BBC website has some video highlights of the maps featured and a link to Maptube, a free resource for viewing, sharing, mixing and mashing maps online, created by UCL's Centre for Advanced Spatial Analysis.
