Bibliographic information was presented using five different prototype systems, including four different visualizations of FRBR-based bibliographic information and one more traditional bibliographic information system. This study reports user performance and perceptions using the same tasks across the different visualizations. Users include undergraduate students of a large university in the USA. The study's methodology is based on a continuation of a study testing the same prototype interfaces in Slovenia, with a number of modifications. The findings show visualization displays performing better on a number of measures than the traditional library catalog interface. A comparison of results highlights some of the differences in findings between the two groups of users. The paper concludes with a discussion on the implications for the design of future bibliographic information interfaces.

The model of bibliographic entities defined in the IFLA Functional Requirements for Bibliographic Records (FRBR) represents a major transition from the digital card catalog to databases containing a rich structure of entities and relationships with well-defined semantics. However, the question of how to best search and present this entity-centric bibliographic data remains a challenge. In this paper we present a system for entity-centric search and a user study on how the displays of the FRBR entities compare in their ability to support different user tasks.

Introduction. Over the last years, we have seen a growing interest in understanding user experience. There are, however, many factors that shape the user experience and studies are only starting to discover the interrelationships between different dimensions and factors. This paper aims to add to this body of knowledge by examining influences on pragmatic and hedonic aspect of user experience. Method. The paper builds on the data collected in a user study of five bibliographic information systems that applied performance as well as user experience measures. Analysis. The analysis focuses on the results collected using the reaction cards method. The cards are grouped by pragmatic/hedonic and positive/negative aspects and the results of individual category analysed in the context of other study variables. Results. The results show that participants selected more cards representing pragmatic than hedonic aspect. Time-on-task and perceived task difficulty represented the strongest factors that influenced on the choice, while the influence of task success and exposure was smaller. The changes in success or perceived difficulty had more effect on the pragmatic than hedonic attributes. Conclusions. Despite some limitations, the study presents a starting point for analysis of user experience through reaction cards and points to future research questions.

We conducted an eye-tracking study in two digital libraries to examine how users orientate themselves on the digital library homepages, how fast and by which actions they initiate the search process. Results showed that participants typically started their task by querying. However, there were some differences in the elements they fixated on first, the way they started the search and the time they needed to orient on the page. These differences seem to have been caused by the homepage layout, especially by the search box position. This shows eye-tracking can be used to examine first actions in digital libraries and could be useful for designing better interfaces.
