Bibliographic information systems are the gateway to the wealth of informationheld and produced by libraries. However, despite their importance for discovering and exploring library resources, bibliographic information systems are still missing some of the core functions they should be providing to support users in their information seeking process and the tasks of finding, identifying, selecting, and navigating the resources. Our research looked at how we could better fulfil the missing objectives by proposing a model that could support a more efficient and user friendly presentation and navigation in user interfaces of bibliographic information systems. We have built our work on the concepts of work family, FRBR (Functional Requirements for Bibliographic Records) and information visualization, creating a model on how to bring together and present all versions of a work, related works, and other works by and about the author. The thesis describes all stages of model development and shows how the model was implemented into a FrbrVis prototype system. It further reports on two user studies, a formal experiment and an observational experiment that have been carried out to evaluate the usability of the proposed prototype system designs. Comparing four information visualization designs between themselves and comparing a FRBR-visual approach against a current bibliographic information system, the results showed that all FRBR-visual prototypes offered better user experience than the baseline system, but the hierarchical indented tree and sunburst design proved as the best, both in performance as well as user preference. The thesis also reports on usability issues discovered during the evaluation and gives pointers for future research.
