Coaching Management, 13.5, April 2005, http://www.momentummedia.com/articles/cm/cm1305/bblibero.htm
Beginning with the 2006-07 season, all states that follow National Federation rules will be required to implement the libero position into high school play. The decision to make this change was approved by the NFHS Volleyball Rules Committee and Board of Directors in January.
Last season, 10 states experimented with the libero position, with positive results. All states will be allowed to implement the rule change in 2005-06 if they so desire.
For a complete rundown on the decision, as well as a list of rules accompanying the libero position, go to the NFHS’s Web site: at www.nfhs.org, click on "Sport & Rules Information," and then "Volleyball."
