Abstract: This application discloses a novel protective case for Golf Documents. Golfers typically use protective cases for yardage books or green guides and consult these documents frequently during a round of golf. The claimed invention uses a means for securing one of the covers to the Golf Documents and locks it into place within a sleeve built into the case. This allows the other cover for the Golf Documents to rest unsecured within a separate sleeve. When a golfer consults their Golf Documents, one cover is secured in place and the other moves freely within a protective sleeve. This allows the golfer to repeatedly open and close the book without damaging the Golf Documents.
