SNAC's research and development work is demonstrating the feasibility of separating the description of people from the description of the historical records that were created by them and that document their lives and work. This separation serves two complementary objectives: improving the economy and effectiveness of archival description and providing researchers with a novel tool that integrates access to distributed historical records and reveals the social context within which the records were created.
The descriptions that constitute the bulk of the source data for the work are in three forms:
Currently, SNAC is working with nearly 190,000 finding aids contributed by scores of repositories, 2.2 million MARC21 descriptions contributed by OCLC WorldCat, and approximately 500,000 original descriptions of people contributed by the British Library, the U.S. National Archives and Records Administration, the Smithsonian Institution Archives, and others.
Data Processing Methods
Processing of the source data takes place in three steps.
Each step in the processing is performed by one of the three SNAC collaborators. The first step, extracting/assembling, is done at the Institute for Advanced Technology in the Humanities, University of Virginia. The second step, matching/combining, is performed at the School of Information, University of California, Berkeley. The third and last step, developing the public research tool, is being carried out at the California Digital Library, University of California Office of the President.
The U.S. National Endowment for the Humanities (2010-2012) and the Andrew W. Mellon Foundation (2012-2015) have funded the R&D. The web site for the first phase of the R&D phase is maintained here.
