Abstract

The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

Abstract

Considers whether standards are needed for OPAC interfaces. Examines issues surrounding calls for standards for OPAC interfaces. It is unlikely that one interface will be accepted by vendors. The role of the OPAC is changing so rapidly there is little chance of standardization

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

Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards

Abstract

Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction

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

The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user

Abstract

Faceted navigation is already a standard feature of contemporary Online Public Access Catalogs (OPACs). The article aims to indicate practices in this area and new affordances that faceted navigation provides. The content of 55 Polish university library websites and their OPACs using faceted navigation was analyzed. After selecting the subject facets, the source of the terms constituting their content was analyzed using the MARC 21 bibliographic record format structure. During the transfer of traditional KOS affordances to those of faceted navigation, the former knowledge organization (KO) structures were deconstructed, which may require the creation of a new kind of KOS.

Abstract

Discusses and illustrates the essential features of user-system interfaces designed to support end user searching. Presents examples of interfaces to support the following basic information seeking functions are presented: problem definition, source selection, problem articulation, examination of results, and information extraction. Argues that present interfaces focus on problem articulation and examination of results functions, and research and development are needed to support the problem definition and information extraction functions

Abstract

The study assessed the ability of children to categorise concepts that will be used to organise an information retrieval interface. The work was done of Project SEED (Science for Early Educational Development), a project to develop hands-on science programmes for elementary schools. Aims to tailor an interface to the particular skills of children in organising science knowledge. The results are promising for the design of IR interfaces based on children's abilities to manipulate information.
