The document outlines a series of projects funded by the Andrew W. Mellon Foundation focused on surveying and assessing unprocessed and underprocessed archival collections across various institutions, including the Historical Society of Pennsylvania, University of Virginia, Columbia University, and others. These surveys aim to collect data on physical and intellectual access, preservation needs, and research value, ultimately guiding processing priorities and improving accessibility to the materials. The initiative reflects a collaborative effort to enhance collection management and public access to archives in special collections libraries.
