ArchiveGrid is a collection of over two million archival material descriptions, including MARC records from WorldCat and finding aids harvested from the web. It’s supported by OCLC Research as the basis for our experimentation and testing in text mining, data analysis, and discovery system applications and interfaces. Archival collections held by thousands of libraries, museums, historical societies, and archives are represented in ArchiveGrid.
ArchiveGrid provides access to detailed archival collection descriptions, making information available about historical documents, personal papers, family histories, and other archival materials. It also provides contact information for the institutions where the collections are kept.
Thanks to Peter Manning at Stony Brook University for informing me about this web site.
