In 1997, the New York Public Library received a very impressive map collection from the estate of the late Lawrence H. Slaughter. Four years later, the remainder of his collection was also given to the Library's Map Division. It is certainly a tremendous offering, and these maps are offered as part of the New York Public Library's Digital Gallery site. Visitors to the site can look over 1000 maps of North America that date from the 16th century all the way up to the waning years of the 19th century. Users are free to select from sections that include maps of North America, New York City, Virginia, and diverse others. A few of the gems offered here include an early map of the plan for Washington, D.C. and a chart of the West Indies from 1702.
