Open for research with select materials restricted as noted. Brittle or damaged items are available at the discretion of RAC. Material in the Rockefeller family collections that provides the names, correspondence, or activities of living members of the Rockefeller family, and/or documents the net wealth of any Rockefeller family members, is restricted from access. Researchers interested in accessing digital media (floppy disks, CDs, DVDs, etc.) or audiovisual material (audio cassettes, VHS, etc.) in this collection must use an access surrogate. The original items may not be accessed because of preservation concerns. To request an access surrogate be made, or if you are unsure if there is an access surrogate, please contact an archivist.
