    Abstract
    Purpose - This study aims to investigate the effects of different search and browse features in digital libraries (DLs) on task interactions, and what features would lead to poor user experience. Design/methodology/approach - Three operational DLs: ACM, IEEE CS, and IEEE Xplore are used in this study. These three DLs present different features in their search and browsing designs. Two information-seeking tasks are constructed: one search task and one browsing task. An experiment was conducted in a usability laboratory. Data from 35 participants are collected on a set of measures for user interactions. Findings - The results demonstrate significant differences in many aspects of the user interactions between the three DLs. For both search and browse designs, the features that lead to poor user interactions are identified. Research limitations/implications - User interactions are affected by specific design features in DLs. Some of the design features may lead to poor user performance and should be improved. The study was limited mainly in the variety and the number of tasks used. Originality/value - The study provided empirical evidence to the effects of interaction design features in DLs on user interactions and performance. The results contribute to our knowledge about DL designs in general and about the three operational DLs in particular.

    Abstract
    The paper presents findings based on user feedback and opinion of online public access catalogues as tools for finding, identifying, and selecting bibliographic materials in a public library setting. Participants spoke their thoughts aloud while conducting known-item searches. The findings describe an iterative process of action, observation, identification, and emotion.

    1. Introduction Significant research in the design and use of online public access catalogues (OPACs) has been conducted by professionals in library and information science (Borgman, 1996; Carlyle, 2001, Carlyle & Timmons, 2002; Hancock, 1987). However, only limited research has addressed actual library user interaction with and perceptions of online catalogue displays and bibliographic elements (Abrera, 1986; Luk, 1996; Markey, 1983). Retrieval systems, specifically online library catalogues, should consider user perceptions and expectations as an important aspect of design and implementation for improved catalogue efficiency (Hert, 1996). Therefore, it is necessary to examine the online catalogue from a user perspective to determine if it is currently succeeding in meeting the bibliographic needs of users in terms of description, display, navigation, and to provide principles for design of future OPACs. A study seeking to understand better how public library users interact with general OPAC displays and the more specific displays of bibliographic information was conducted in 2003. Research questions focused an 1) user perceptions of the OPAC, 2) the elements in a bibliographic display standing out as most important in selection and identification, and 3) user feedback an the process of using the OPAC. The purpose of this paper is to highlight the larger study findings having implications for future research and online catalogue design.
