The RFU Rugby Union referee's manual - Richard Greensted

This Rugby Football Union's refereeing handbook is intended as a source of guidance for those wishing to become qualified referees, for referees who are already qualified, and for interested players, coaches and spectators. This second edition has been thoroughly revised and updated and includes helpful sections on: the referee's general management of the game; the scrum, line-out, ruck and maul; the effective application of the Advantage Law; officiating offside and obstructing in open play; the referee's positioning; official's physical fitness; and the demands of touch judging.
