In 1985, The Missing Children Directory® was distributed to Principals of public and private schools in the U.S. This cooperative venture between NCSC and QSP, a subsidiary of the Reader's Digest Association, Inc., involved virtually every school district in the U.S. In support of the effort, NCSC operated a 24-hour-a-day 800 hotline, through which dedicated and fully trained professional specialists received missing children sighting reports.
