Series II. Wendell S. Hadlock Papers contains correspondence, directions for handling Adney’s estate, and newspaper clippings. The newspaper clippings have been photocopied, and the originals are restricted due to fragility. The later correspondence, 1950 to 1952, between Hadlock and Glen Adney (Edwin’s son), document how Adney’s research was divided up after his death, and how Hadlock and the Peabody Museum of Salem came to have the First Nations’ materials.
