Abstract
Purpose
In recent years, aceted search has been a well-accepted approach for many academic libraries across the United States. This chapter is based on the author’s dissertation and work of many years on faceted library catalogs. Not to hope to be exhaustive, the author’s aim is to provide sufficient depth and breadth to offer a useful resource to researchers, librarians, and practitioners about faceted search used in library catalogs.
Method
The chapter reviews different aspects of faceted search used in academic libraries, from the theory, the history, to the implementation. It starts with the history of online public access catalogs (OPACs) and how people search with OPACs. Then it introduces the classic facet theory and its relationship with faceted search. At last, various academic research projects on faceted search, especially faceted library catalogs, are briefly reviewed. These projects include both implementation studies and the evaluation studies.
Findings
The results indicate that most searchers were able to understand the concept of facets naturally and easily. Compared to text searches, however, faceted searches were complementary and supplemental, and used only by a small group of searchers.
Practical implications
The author hopes that the facet feature has not only been cosmetic but the answer to the call for the next generation catalog for academic libraries. The results of this research are intended to inform librarians and library information technology (IT) staff to improve the effectiveness of the catalogs to help people find information they need more efficiently.
This study investigated the design of three online public library catalogs in light of the cognitive ability and success of children ages five to eight.
Abstract
Purpose
This study investigated the design of three online public library catalogs in light of the cognitive ability and success of children ages five to eight.
Methodology/approach
A quasi-experimental approach was employed to examine the influence of system design on children’s searching strategies and search success. Interviews were used to explore children’s rationale for using icons and taxonomies in the catalogs. Fifty one children from one public library participated in this study. Inferential statistics were utilized to whether significant differences existed between use of the catalogs and the children’s success in finding information.
Results
Use of images and text were helpful in searching the catalogs. Results of the ANOVA test indicated no significant difference among children’s searching success rates and the three catalogs. Additionally, the participants misidentified representations used in icons in all three catalogs and created valid search paths that did not produce results. There was a disconnect between the children’s cognitive abilities and the design representations of the three catalogs.
Limitations
The study took place in one location, thus one should not overgeneralize the findings. Use of assigned tasks may have affected children’s success rates. Children’s searching using printed cards of display screens from the three catalogs instead of real-time interaction with them is also a limitation.
Practical implications
Because of the children’s reliance on images, the choice of visual representations is crucial to successful searching. Interface designers should involve young users in the design of today’s online catalogs. They should also consider new forms of representations such as auditory icons, verbal mouse overs, and zooms.
Originality/value
In addition to addressing the need for research on young children’s information seeking and use of online catalogs in public libraries, this research focuses on the need for an additional layer of visual representation and highlights flaws in currently used catalog designs.
