Fonds consists of material relating to Southam's professional life, and personal interests. The fonds is divided into ten series which reflect the many items found in fonds. Materials in the fonds include recordings (both by Southam and by others), scores (both by Southam and others), programmes, articles about Southam, photographs (personal and professional), material used by Southam in mixed-media presentation, and other material.
Fonds consists of records generated by the Association of Canadian Women Composers (ACWC), including the Association’s formation and its subsequent activities. The bulk of the records concern the administration of the Association itself and address issues related to governance, financial management, and member recruitment. Other records concern the Association’s public activities, including sponsorship of concerts featuring works by Canadian women composers and other public initiatives intended to increase awareness of and provide support for Canadian women composers. Records include correspondence, financial records, minutes, publications, press releases, media clippings, membership records and other material.
