    Abstract
    Usability evaluations and observations of users shopping at Amazon.com (http://www.amazon.com) revealed some interesting user behaviors. The mixed behavior patterns were leveraged to create an interface for an e-commerce product. The author describes some design practices for providing a scoped search interface for an e-commerce site.

    Abstract
    Current research on user interfaces to online public access catalogs is reviewed in an attempt to identify research methods and findings applicable to the design of effective user interfaces to online public access catalogs. A broad definition of user interface is employed which includes data structures, in addition to searching and indexing software. The following features of online public access catalogs are discussed: the demonstration of relationships between records, the provision of entry vocabularies, the arrangement of multiple entries on the screen, the provision of access points, the display of single records, and the division of the catalog into separate files or indexes. For each feature, user studies and other research on online public access catalogs are reviewed and those findings summarized which provide insight into user needs concerning that particular feature; issues are identified and directions for further research are suggested. Implications for cataloging codes and standards and system design are discussed

    Abstract
    A research project at Middlesex Polytechnic is examning the problems of subject access in an OPAC. A series of user studies have been carried out which examined students' use of existing catalogue facilities, which in turn led to the experimental evaluation of various interface designs for an online catalogue. The experiments were primarily concerned with the effect of the following variables on the speed and accuracy of retrieval of specific items, the use of colour, the speed of presentation of information, the amount of information on a screen, the paging and scrolling of information, the position of a sought item within a list

    Abstract
    In this paper, we report on the second part of an empirical study designed to observe how users interact with World Wide Web resources. Applying a holistic approach, the researches examine users' cognitive, affective, and physical behaviors during user-Web interaction in order to understand better the nature of information retrieval on the Web, the needs of Web users, and the problem-solving strategies Web users employ. From analyses and the participant verbalizations collected during monitored searches, the researchers developed a taxonomy of problem solving strategies. The coding scheme was developed based on a content analysis of the integrated process data. Information from triangulation follow-up with participants via anonymously completed questionnaires, the taxonomy, and analyses of search transcripts were collected to determine 1) what problems users encountered during the interaction and how users solved these problems; and 2) which problem-solving strategies Web users considered and selected for finding factual information. The focus of the coding was on the participants' cognitive, affective, and physical behaviors in response to the components of the problems encountered, which included problems of the following types: Web interfaces, users' mental models, and the Web information sources. Searching behavior and problem-solving patterns are described and interpreted within the relevant situational context and the problems users encountered are identified and analyzed. Both the problems users faced and their problem-solving approaches endeavored evidence a strong reliance on mental models of the features available on sites, the location of those features, and other interface design concepts

    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.

    Abstract
    Presents the selected findings of a research project based on the British Library Network Online Public Access Catalogue (NOPAC) carried out in the department of information and library management at the University of Northumbria in Newcastle, UK over the academic year 1994/95. Data was collected by means of interviews with NOPAC users especially on use made of the NOPAC and on attitudes towards the NOPAC's interface. Discusses the views of users as they relate to: display features; mode of interaction; help/user assistance; extra features available; and usability. Lists important points which emerged from the survey concerning the NOPAC service
