"Bibliography of cartography or A descriptive list of books and magazine articles relating to maps, map-makers and views," by Philip Lee Phillips, F.R.G.S., Chief, Division of Maps, Library of Congress. The volumes appear to be a 1920 version of Phillips' typescript, heavily annotated in various hands with additional information and editing marks. They include references to "Supplement" and have at least one manuscript addition with the date 1928.
