The Jeanette Alexander papers consist primarily of incoming correspondence, from several friends and family members, including correspondence from her son, Earl Alexander,Jr., and his girlfriend Dolores, regarding his service in the United States Army Air Forces. Much of the material within the collection was composed by Earl (19 letters and two telegrams) and Dolores (21 letters), with other contributors including his parents, Earl Alexander, Sr., and Jeanette Alexander, as well as several family members and friends. The earliest items in the collection are three report cards of Earl Alexander, Jr.'s academic progress for second (1931-1932), third (1932-1933), and fifth (1934-1935) grades and a manual answering frequently asked questions for a driving exam. Several other early letters written to the younger Earl Alexander relate his parents' experiences traveling in Florida in February 1938. The letter of February 22, , in which they mentioned their intention to travel to Havana, Cuba, includes several pages of stationary illustrating leisure pursuits in St. Petersburg, Florida.
The remainder, and bulk, of the collection dates to the Second World War, and opens with Earl, Jr.'s correspondence from his year at Rutgers University; he described scenes from his collegiate life and discussed the likelihood of conscription, as well as its effect on his future. Following a May 7, 1943, telegram ordering him to appear for a military mental exam, the collection focuses on his military service, related primarily through the communications of his girlfriend Dolores. Dolores, then a student at Mary Washington College at the University of Virginia, frequently wrote to Jeanette Alexander, providing updates on her life in Fredericksburg and news from Earl, and commenting on the effect of soldiers' absences on those remaining at home. Earl also composed several letters to his parents, the majority of which date from his time in Fort Wayne, Indiana, where he awaited his final orders. Six letters from Ella Garza, whose husband Rudolf served with Earl, round out the collection, which concludes with a December 4, 1945, telegram from Earl reporting his expectation of an imminent return home.
