Color Landform Atlas of the United States
Images of US states: shaded relief, false-color satellite view, and maps from an 1895 atlas.
Earth Viewer (European mirror site)
From Fourmilab in Switzerland.  Just for starters, "you can view either a map of the Earth showing the day and night regions at this moment, or view the Earth from the Sun, the Moon, the night side of the Earth, above any location on the planet specified by latitude, longitude and altitude, from a satellite in Earth orbit, or above various cities around the globe."
Perry-Castañeda Library Map Collection (University of Texas at Austin)
You can download many simple reference maps published by the CIA.
Peters Projection (call numbers below)
This is a world map that uses a much publicized equal-area projection to heighten awareness about how the choice of map projections can affect or be affected by one's view of the world.  This projection, however, was not devised in 1974 by Arno Peters as he claimed but was first published in the 19th century by James Gall, called Gall's Orthographic Equal-Area Projection. Even then, it wasn't the first nor is it the most visually appealing projection that maintains correct area relationships.  See article by Jeremy Crampton in Cartographica, 31(4), pp. 16-32, for a longer discussion, or the discussion by Matt Rosenberg at
The Map Collection has copies of the map at Oversize G3201 .B72 1984 .O9 (laying on top of the cabinets of the "G" schedule), as well as an atlas at Map Coll. Ref. Oversize 912 P481, P481, 1990.
United Nations Cartographic Section (version français)
The Maps and Geographic Information page leads to online maps in Adobe Acrobat format: both general reference maps as well as deployment maps for peacekeeping missions.
