The first instance of The Call Sheet (PDF) is dated April 1989. The 3 page newsletter was "an attempt to establish a line of communication among callers of the International Association of Gay Square Dance Clubs". Written by Anna Damiani, it did not yet use the name "Gay Callers Association". Harlan Kerr sent out a 24 page Lambda Calling (PDF) newsletter and note service dated May 1989. It uses the name "Gay Callers Association" and gives some of the history within the IAGSDC. Both of these early newsletters laid the groundwork for the 1st GCA Caller School in New York that Summer at convention.
