In this study, the researchers submitted a music score approval plan survey to all ARL libraries. Two surveys were created, one for libraries with music score approval plans, one for those without. Forty-four surveys were returned. The authors’ purpose was to analyze and discuss the survey results, incorporating elements of the scholarly work preceding this study. Discussions, roundtables, and listservs participated in by music librarians over the years formed the basis of the topic at hand. The goal was to ascertain whether these discussions and underlying assumptions of approval plans held true to the real world.
