Project Background This Pilot Project was first conceived in May 1999 to provide Web access to high use maps from the University of California-Berkeley's Earth Sciences and Map Library's collection. One-time funds were requested and received from the Library's collections budget to cover scanning and other project costs. The U.S. Geological Survey's topographic quadrangles of the San Francisco Bay region were selected for digitizing. These maps are in the Public Domain and have no copyright restrictions, plus the geographic area selected would be a high use to our primary clientele and of interest for off-site users. Access is provided to both the 15- and 7.5-minute USGS topographic quadrangles, spanning more than 100 years of mapping (1885-1999). Geographic coverage extends from Pt.
