The University of Texas is host to the Perry-Castañeda Library Map Collection. The bulk of the collection is the usual standard fare with maps of the world, continents, historical maps, and on and on and on.
But it is two features that really appeal to me. One feature is a link list of other sites loaded with maps from the world to street level. The thing that caught my eye; however, is on top of the main page. Maps of Current Interest has links to maps or images that are in the news. Things like a satellite image of the al-Askari Shrine, Turin Olympics Map, and Latin American elections map prove timely.
