Mud river sections of southwestern West Virginia, particularly focusing upon Cabell,
Wayne, and Lincoln counties. The historical range of his 500 notebook collection, which is housed at James E. Morrow Library at
Marshall University, is 1840s to 1940s. The notebooks include genealogical and historical material, interview notes, and photographs. Lambert's
The Llorrac (1926) is the second history compiled about
