Ruby Terrill Lomax and John Avery Lomax produced folklife documentary work that comes up a lot when I am researching East Texas History. Along with her husband John Avery Lomax, Texas folklorist Ruby Terrill Lomax traveled the state and other Southern regions for the 1939 Southern States Recording Trip. The Lomax’s multi-genre journey documented Southern folk musicians and their communities through sound recordings, photographs and other ephemera, and spends valuable time in communities of Color and documenting the creative contributions of incarcerated people. The collection’s primary home is in The American Folklife Center, Library of Congress.
Here are a few items of interest from the collection:
