The New York Public Library has three major digital exhibitions currently running to complement their in-house exhibits. Together, these exhibits constitute a marvelous introduction to Western history via primary documents and images from the era. Heading West examines the exploration and development of the West using maps from the library's collections. The accompanying text is well written and addresses itself to exploding some of the myths about the Frontier, including the myth of the West as settled by lone pioneers. The maps are fascinating and allow for viewing in several sizes. The 1859 map of the US and Mexico is worth a visit by itself; visitors can view both territories in their entirety or zoom in to a level where geographic features and the names of individual towns and territories can be made out.
