    Abstract
    This article describes the findings of a research project that tested a new subject-access design in an experimental online catalog that had a wide range of subject-searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Library users at 2 academic libraries searched this experimental catalog for topics of their own choosing, judges the usefulness of retrieved titles, and answered post-search questions about their searching experiences. Mixed results from a quantitative analysis (i.e., precision scores) were supplemented with the more conclusive results from a qualitative analysis (i.e., failure analysis). Overall, analyses demonstrated that the new subject-access design that featured search trees was more effective in selecting a subject-searching approach that would prooduce useful information for the subjects users seek than users would select on their own. The qualitative analysis was especially helpful in providing recommendations for improving specific subject-searching approaches to increase their effenciency, increase user perseverance, and encourage browsing. It also suggested enhancements to the new subject-searching design to enable systems to respond to the wide variety of user queries for subjects

    Abstract
    Describes a study to investigate end user understanding of subdivided subject headings in their current form and in the form proposed by the first recommendation of the Library of Congress Subject Subdivisions Conference. The impetus for this study was a charge by the Subject Analysis Committee of the ALA to respond to the first recommendation of the LC Subject Subdivisions Conference that proposed standardizing the order of subject subdivisions. Questionnaires bearing subdivided subject headings in the 'current' form and in the form proposed were distributed to users and professional cataloguers who were asked for the meaning of individual headings. The end users' responses to cataloguers' responses were compared to determine end users' level of understanding of subdivided subject headings. An analysis of end user interpretations demonstrated that they interpreted the meaning of subject headings in the same manner as cataloguers about 40% of the time for 'current' forms of subject headings and about 32% of the time for 'proposed' forms of subject headings. Concludes with specific recommendations about the first recommendation of the LC Subject Subdivisions Conference and general recommendations about increasing end user understanding of subdivided subject headinbgs
