Avrom Litin asked about goalies playing with a broken stick.
Brian Sprague has already answered that it's ok, but I thought
for completeness I'd give the reference:
 
NCAA 6-5b       A goalkeeper may continue to play with a broken
        stick until astoppage of play or until the individual
        legally has been provided with a stick.
 
USA Hockey 605b Essentially the same wording.
 
But note however that in Canada ...............
 
CHA 51a,c       ... A player or goaltender whose stick has been
        broken must drop the broken protions to the ice immediately.
        A minor penalty shall be assessed for an infraction of this
        rule.
                ... A goaltender may not continue to play with a
        broken stick of any kind.
