Abstract: Records of a commission whose purpose is to develop statements of stratigraphic principles; review problems and recommend procedures applying to classification and nomenclature of stratigraphic and related areas. Most of the collection consists of general files, arranged chronologically, containing correspondence, minutes of meetings, and reports of the NACSN. The general files document annual meetings of the commission; the development and revisions of the stratigraphic code; activities of subcommittees; and the writing of the Commission's published notes and reports.

The collection also contains extensive files of the Code Committee (1977-1983) which coordinated a complete revision of the code. The Code Committee files include scattered records of its subcommittees. The records of the Quaternary Advisory Group contain correspondence, minutes of meetings, and reports concerning terminology and stratigraphic principles and applications of Quaternary stratigraphic concepts.
