Buenger has written or co-written four books, co-edited three more, and authored numerous articles and book chapters. His main areas of interest have been the connections between Texas and the South, Texas identity, historiography, the role of memory, the influence of borders, and the construction and evolution of culture in the Southwest. He recently completed a co-edited and extensively annotated version of the autobiography of William A. Trenckmann, a German language newspaperman and politician who was born in Texas in 1859 and died in Austin in 1935. He is also writing a re-conceptualization of Texas and the Southwest with the tentative title, “Texas Since 1800:  Patterns of the Past, Patterns of the Present"
