The Professional activities series consists of materials pertaining to Weisberg’s work as a curator and critic; her affiliations with professional organizations, including the College Art Association; her involvement with feminist art and organizations; and her involvement with Jewish arts organizations. There is overlap with the Correspondence.

The Correspondence series consists of correspondence, notes, clippings, exhibition announcements, and catalogs. It also consists of both personal and professional correspondence, since Weisberg did not distinguish between the two. See also the Art, Professional activities, and Education and teaching series.
