His place of residence and annual averages can be found in the Interstate Association and American Trapshooting Association (later Amateur Trapshooting Association) annual average books. Some information about the Grand can be found in these same books and Jimmy Robinson's 3 books, which includes The Grand, 75 Years. Early trapshooting marks can be found in D.H.Eaton's book, Trapshooting, The Patriotic Sport. If you know the date of a particular shoot, you can often find results in Sportsmen's Review or, later, Trap and Field.
