The Anna Y. Moulton Papers consists of course records, memorabilia, correspondence, and biographical information. The material in the collection relates mainly to her years as a Mount Holyoke College student, 1912-1916. These papers consist primarily of course records, including compositions and notes. The records are for English language courses and there is also a paper written for a philosophy class. The compositions include comments written by English teachers Helen Griffith and Caroline Foote Lester. Topics of her compositions include "The Foreigner at Home," "The Principal Subjects of Education," "Books and Progress," and "How to Start an Automobile." She also writes about aspects of her life at Mount Holyoke, including President Mary Emma Woolley ("My first impression of Miss Woolley"), student housing ("The Present System of Room-Choosing"), and religious activities ("The System of Compulsory Chapel"). Memorabilia consists of Moulton's speech to the Class of 1916 at their 25th reunion in 1941, a booklet from that reunion, and a letter written to the Class of 1916 on February 13, 1947. Correspondence consists of letters from one of her classmates, Priscilla Larned Clarke Dinsmoor, and from Mrs. William W. Hildreth, one of her colleagues from East Jaffrey High School, congratulating her after the birth of her first son in August 1921. Correspondence also includes twelve letters and cards from Mount Holyoke president Mary Emma Woolley, 1934-1947, and a letter from Jeannette Marks dated November 11, 1944 concerning Woolley's health after suffering a stroke. The biographical information consists of two biographical notes circa 1923 and circa 1937, as well as newspaper clippings about Class of 1916 activities, circa 1930s-1941, and Moulton's obituary, September 28, 1965.
