Scanning and Georeferencing Historical USGS Quadrangles
From USGS website

The USGS Historical Quadrangle Scanning Project (HQSP) is scanning all scales and all editions of approximately 250,000 topographic maps published by the U.S. Geological Survey since the inception of the topographic mapping program in 1884.  This scanning will provide a comprehensive high-resolution digital repository of USGS topographic maps, available to the public at no cost.

Although these historic maps are out-of-date, they are often useful to scientists, historians, environmentalists, genealogists, and others researching a particular geographic location or area. A series of maps of the same area published over a period of time can show how some areas looked as early as 1884, before current development, and provide a detailed view of changes over time.

This project serves the dual purpose of creating a master catalog and digital archive copies of the irreplaceable collection of topographic maps in the USGS Reston Map Library as well as making the maps available to the public for viewing and downloading. The product will be delivered in two formats:  georeferenced GeoTIFF images with embedded metadata, and compressed GeoPDF® files. The scanned maps will be added to the USGS Store and The National Map Viewer as they become available beginning in mid-2011.
