Like the earlier general correspondence processed under the previous subseries, this correspondence documents the interaction of Johnson Collection staff with individuals from institutions based locally and around the globe. City officials, scholars, publishers, collectors and museum colleagues are among the correspondents. Not surprisingly, each Johnson staff member communicated regularly with PMA staff. During processing, such memoranda were collocated and filed in chronological order in folders identified as "Philadelphia Museum of Art." Any requests for photographs and other inquiries received after 1980 are also included with no special designation as such. These letters are simply filed by name of individual or institution.
