The Correspondence series contains six subseries: Alumni Correspondence, Building Correspondence, Executive Council Correspondence, Fraternity Business, Officer Correspondence, and University of Michigan Housing Division Correspondence. Records within these subseries that are enclosed in titled folders are arranged alphabetically by subject; all other documents are arranged chronologically. The Alumni Correspondence subseries contains letters sent either to or from Alpha Chapter alumni during the time periods listed. The subject matter of these letters is usually personal and not related to the subjects of the other subseries. The Building Correspondence subseries contains records that relate to two separate periods of construction in the history of the Alpha Chapter: the construction of its first chapter house, in 1906, and the restoration of that house in the 1960s. The Executive Council Correspondence subseries contains two folders that overlap chronologically. The Fraternity Business subseries contains correspondence that pertains to both the Alpha Chapter (also known as the Nu Sigma Nu Corporation) and the national organization of Nu Sigma Nu.
The Officer Correspondence subseries contains the correspondence of several key people within the Nu Sigma Nu fraternity, either nationally or locally. The files are arranged alphabetically by the last name of the officer (or by one of the officers, if it contains more than one person). The subject matter of these correspondence is far-reaching and varied, ranging from the construction of the first chapter house to collecting house dues to managing the affairs of the national organization. Some of the officers' correspondence is still housed within their original filing system. Of particular interest is the correspondence of Frederick G. Novy, who served as Secretary for the Corporation of the Alpha Chapter of Nu Sigma Nu for several years. One set of correspondence was taken directly from Dr. Novy's own filing system and dates from 1902 to 1913. Additional correspondence of Dr. Novy is organized chronologically from 1911 to 1923. The subseries University of Michigan Housing Division Correspondence contains one folder of general correspondence and one folder pertaining to a 1986 incident that called into question the legal status of the Nu Sigma Nu Corporation and the ownership of the Alpha Chapter house.
