One of the few serious, scholarly studies to explore the modern Southern Plains notes that “few commentators have turned their attention to the” vast region. Journalists, academics, and other writers have often overlooked a transformative part of the Southern Plains’ history—its Chicana/o Civil Rights Movement. Moreover, the few scholars who have covered moments of the region’s Chicana/o Movement have not drawn those events together. Nevertheless, the Chicana/o Activism in the Southern Plains Through Time and Space project was in part built on those foundational works. Chicana/o historians, after all, stand on the shoulders of those who courageously built the field. Arnoldo De León, the most prolific Tejano historian, detailed activism during the Chicana/o Movement in San Angelo, which sits at the southeastern edge of the Southern Plains, in San Angeleños: Mexican Americans in San Angelo, Texas. Scholars and social commentators have also covered the Chicana/o Movement of Lubbock, Texas. This study made use of Nephtalí De León’s groundbreaking Chicanos: Our Background and Our Pride and Andrés A. Tijerina’s History of Mexican Americans in Lubbock County, Texas. Two dissertations were also invaluable to the project: Yolanda G Romero’s “The Mexican American Frontier Experience in Twentieth Century Northwest Texas” and Virginia Marie Raymond’s “Mexican Americans Write Toward Justice in Texas, 1973 -1982.”
The roots of this digital history project, however, originate from extensive oral history fieldwork done through the Civil Rights in Black and Brown Oral History Project, archival research, and the thorough mining of newspaper sources. The Bidal Agüero Papers and the Ernestine Cox Herren Papers at Texas Tech University’s the Southwest Collection provide vital sources for anyone studying ethnic Mexicans in the plains, especially the Chicana/o Movement. Finally, this project relied on the following newspapers: The Abilene Reporter-News (Abilene, TX), The Albuquerque Journal (Albuquerque, NM), The Amarillo Globe-Times (Amarillo, TX), The Brownwood Bulletin (Brownwood, TX), The Burlington Free Press (Burlington, VT), The Childress Index (Childress, TX), The Corsicana Daily Sun (Corsicana, TX), The Del Rio News Herald (Del Rio, TX), El Editor (Lubbock, TX), The Longview News-Journal (Longview, TX), The Lubbock Avalanche-Journal (Lubbock, TX), The Roswell Daily Record (Roswell, TX), The Santa Fe New Mexican (Santa Fe, NM), El Tiempo Chicano (National City, CA), and The Town Talk (Alexandria, LA).
