The records of the Wisconsin Section of the American Chemical Society consist of a history of the section, a constitution and bylaws, minutes, correspondence, newsletters, lecture notices, rosters, a sampling of membership applications, annual reports, and treasurer's reports. Also included are mimeographed materials from the national office of the American Chemical Society: annual reports, a constitution and bylaws, newsletters, and reports of national meetings. The materials are divided into Wisconsin records and national records, then arranged alphabetically by type of document.

The first item in the collection is a History of the Wisconsin Section written by Aaron J. Ihde in 1957. It includes lecture lists through 1957 and officer lists updated through 1965. A reprint of an article on the early days of chemistry at the University of Wisconsin can also be found at the end of the History.

The Correspondence concerns (1) arrangements for lectures at section meetings and (2) miscellaneous topics including sectional boundary adjustments, a visiting scientist program for high schools, a proposed resumption of Midwest regional meetings, the James Bryant Conant award, and Fifty-year membership awards.

The largest quantity of materials is the Secretary's Records. These include minutes, lecture notices, clippings, and occasional correspondence, all bound in four volumes.
