Staff members of the Weber County Library System in Utah were studied in a research project to determine the effect on staff knowledge of library policies and procedures of (1) an employee handbook and (2) the handbook supplemented by a formal orientation procedure. Data were obtained from three randomly selected groups of library staff members in a pre-test, post-test situation. After administration of the pre-test, one group received the staff handbook, one received the handbook and an orientation, and the control group was given neither the handbook nor the orientation. The post-test was administered two months later. Analysis of covariance revealed a significant difference in the gain scores of all groups. The data suggested that a handbook used in conjunction with a formal orientation session was significantly better than the use of the handbook alone. The questionnaire and handbook are appended.
