The correspondence is arranged alphabetically and comprises both incoming letters to Glines and letters from Glines to his mother, Ellen Lanza Owen. The letters document his personal and family life and his life as a high school student and an undergraduate at Yale. To a lesser extent they document his career as a writer and theatrical producer, and his contributions to the gay artistic and political milieu in New York. The most substantive portion of the correspondence concerns Glines's personal life. Of particular interest are his letters to his mother as a young adult. There are no letters documenting his intimate relationships with men.
