This paper examines the efforts made by the American Library Association (ALA) and the Mexican Border Traveling Library Service (MBTLS) to ensure that remote World War I outposts, such as the Gerstner Field aviation and military training camp in Louisiana, would have adequate library service. A history of the MBTLS' early organizational success, the ALA's cooperation with the MBTLS and the Young Men's Christian Association (YMCA), and descriptions of the establishment of Gerstner Field's circulating library building are presented. Also provided are details of how the library later fell under the jurisdiction of the MBTLS under the directorship of Harriet C. Long and grew to a collection of several thousand volumes before it was disbanded after the end of the war. (30 references) (MAB)
