The York County records were intensively abstracted and arranged into a biographical index by the Colonial Williamsburg Foundation Department of Historical Research as part of a National Endowment for the Humanities grant. A microfilm copy of that index is available, along with microfilm of the original York County records. The Colonial Williamsburg Foundation is one of four institutions that own the VCRP microfilm series. Printed survey reports in the Rockefeller Library are increasingly accessible through the online index to the VCRP on the Library of Virginia web site. Additional compilations of manuscript materials relating to colonial Virginia have been microfilmed at the Huntington Library, Duke University, the Newberry Library, the Library of Congress and the Virginia Historical Society, among others.
Catalog records for each microfilmed collection detail ownership and any restrictions.
The microfiche collection includes the Early American History Research Reports from the Colonial Williamsburg Foundation Library, which are provided to researchers throughout the United States on interlibrary loan. While there are original maps to be found in the rare book collections of the Rockefeller Library, the map collection in the Special Collections reading room is primarily composed of photostatic reproductions of original maps. Each subdivision of the map collection is arranged chronologically and by size. Named collections include the Wood Collection, the Rochambeau collection, and the Simcoe Collection. Because most of the maps are copied from originals in other institutions, written permission of the owning institution may be required in order to copy or cite any given map.
