Ouachita Baptist University's Riley-Hickingbotham Library's Special Collections houses the institution's own historical materials. Among other treasures are the papers of Senator John L. McClellan and the Thase Daniel collection of wildlife photography and field notes. In addition, Special Collections serves as the official depository for the archives of the Clark County Historical Association and the Arkansas Baptist State Convention. In conjunction with the latter, the university has materials covering Arkansas and Baptists, particularly Southern Baptists.
