Traditionally, Crowder College Lee Library has presented service output information to the Board of Trustees and college administration to express library effectiveness. Such efforts, while laudable, do not offer non-librarian leaders information on what impact service numbers have on greater institutional goals and objectives. Administrators need the “why” regarding library services. Crowder College began a prototype statistical analysis of library service relationship to retention. This presentation communicates that experience, provides results, and expresses methodology considerations in a way that affords library administrators an opportunity to enhance their program review reports.
