While the libero was not allowed to serve when the position was first introduced to competitive volleyball in 1998, the rules have since changed in some competitions. In events sponsored by the FĆ©dĆ©ration Internationale de Volleyball (FIVB), the sportās governing body, the libero still is not allowed to serve. However, other organizations, including the NCAA, allow the libero to serve only for one player in each rotation.
