A coach brought out a rule book to settle an issue. The opposing team’s coach objected saying that it’s not allowed to bring a rule book onto the field. That is a myth. There is no rule against having a rule book on the field. I remember this question coming up in an umpires clinic I attended many years ago and the veteran umpire leading the clinic actually recommended that umpires always carry a copy of the rule book with them on the field. His reasoning was that it’s better to spend a few minutes on the field with the book to settle a rules question rather than risk a protest and having to replay an entire game. "There ain't no rule in the rule book about bringing a rule book on the field." (Earl Weaver, Hall of Fame manager - Baltimore Orioles 1968-82 and 1985-86) Richard Rickard, Umpire-in-Chief 2014
