Title: THE DEVELOPMENT AND METHODOLOGICAL STUDY OF AN INSTRUMENT FOR MEASURING MATERIAL AVAILABILITY IN LIBRARIES
Abstract: The primary objective of this research was to develop an instrument for measuring library performance based upon the outcomes of both known-item and subject card catalog searches. A second objective was to explore the methodological feasibility of utilizing the instrument in an academic library using both obtrusive and unobtrusive observation techniques. The final objective of the study was to examine patrons' subject search purposes, motivations, and satisfaction and to determine if relationships among these factors exist. The data were collected in a publicly supported college library by questionnaire and researcher observation.
The development of the instrument for measuring library performance was achieved by expanding the branching technique developed by Kantor and others for use exclusively with known-item search outcomes. This was accomplished by adding to the instrument a second branch detailing the pitfalls associated with subject search failures. Separate performance measures, calculated for both known-item and subject search outcomes, were derived as the products of the success probabilities for each of the respective branches. A single performance measure representing the Ciliberti instrument's measure was then created for the known-item and subject search measures.
No significant difference was found between the measures of the original Kantor instrument and the Ciliberti instrument, despite the latter's inclusion of subject search outcomes. However, when the two instruments were employed using both obtrusive and unobtrusive observation techniques, differences were noted. In both cases the measures derived from obtrusively observed searches were lower than the measures derived from unobtrusively observed searches.
The primary subject search purposes reported were to find factual information and to pursue general reading while the chief motivations were to fulfill class assignments and to conduct personal research. Patrons rated favorably their satisfaction with the amount of material they received and its content. No relationship was noted between patrons' search purposes and their satisfaction ratings.
The major implications of this research are that the measurement of library performance does not appear to be strengthened by inclusion of subject search outcomes and that the validity of patrons' self reporting should be questioned.
