    Abstract
    The human natural ability to store and process images and speech provides clues for improving access to online information. The principles underpinning the maps people use in their minds can be applied to maps that can be presented at the user interface to online systems. Traditional classification organizes information into structured hierarchies and simplifies the search problem, but has serious limitations. Discusses the prospects for improving access to online information through the application of dynamic faceted classification. Presents a glimpse into the navigation of n-dimensional information space for future library OPACs using a modified DDC

    Abstract
    This article reports research that explored children's information retrieval behavior using an OPAC in an elementary school library. The study considers the impact of a variety of factors including user characteristics, the school setting, interface usability, and information access features on children's information retrieval success and breakdown. The study reports the overall patterns of children's behavior that influence success and breakdown in information retrieval as well as findings about the intentions, moves, plans, strategies, and search terms of children in grades one through six

    Abstract
    Explores the variety of user behaviour exhibited by users of information retrieval systems over time and the effort of differences between expert and novice searchers on an understanding of information searching dynamics and on the design of information systems. Based on a naturalistic case study. Points out some of the dynamic patterns of behaviour of children's use of online catalogues (OPACs)

    Abstract
    Describes the design and continuing development of the University of Illinois at Urbana-Champaign Library Information Workstation, which provides the primary, in-library user acces to ILLINET Online Plus, the library's extended OPAC system. Briefly describes the automated library information resources and information processing environment as they have influenced the design and development of the Library Information Workstation. Discusses its philosophy and approach in the context of relevant information access issues and user needs and requirements. Features of the current Library Information Workstation implementation are then described using illustrations focused particularly on integrated access to local (resident on individual workstations) information fields and an integrated end user interface for bibliographic database searching. Ongoing development plans also are discussed briefly

    Abstract
    Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

    Abstract
    For the purposes of library and information science research, transaction lof analysis can be narrowly defined as the study of electronically recorded interactions between online information retrieval systems and the persons who search for the information found in those systems. Researchers most often use transaction log data with the intention of improving an information retrieval system, human utilization of the system, and human (and perhaps also system) understanding of how the system is used by information seekers. Transaction log analysis can provide system designers and managers with valuable information about how the system is being employed by actual users. It also can be used to study prototype systems or potential system improvements

    Abstract
    Many information channels are available to students, but it is now clear how students select and use them. Reports results of a study of the information seeking behaviour of students at 2 US universities: the American University; and the District of Columbia University. The study aimed to investigate: the information channels used by students when they work on course related projects and how they select the channels; how they use ALADIN, an augmented OPAC that provides access to the holdings of the Washington Research Library Consortium and several commercial online databases; and how selected characteristics of students are related to their use of information channels. Students identified convenience and quality of data as the top 2 factors in their choice of information channel. Affirms the value of librarians and of formal information channels, suggests ways to augment the online catalogue, and reminds librarians that equal access to information technology does not necessarily lead to equal use

    Abstract
    The focus of this article is to develop a map display for information retrieval. Through an examination of relationships among visual displays, information retrieval, and browsing, advantages of visual displays for information retrieval are characterized as (1) the ability to convey a large amount of information in a limited space, (2) the potential to reveal semantic relationships of terms and documents; and (3) the facilitation of browsing and perceptual inferences on retrieval interfaces. These advantages are further demonstrated through a map display generated by a neural network's self-organizing algorithm. The map display detects complex relationships among given documents, and reveals the relationships through a spatial arrangement of terms abstracted from the documents. The map display also provides interactive tools to allow the user to interact with the underlying information. Examples of the map displays show that such map displays can be used both as an overview tool and an access or exploration tool, and the map displays will likely increase the amount of information that the user is willing to browse

    Abstract
    In this article I will look at the changig computing resources required to run a large information retrieval system like the MELVYL system. I will give a historical perspective, examining the aerly days of the MELVYL system and how the system has changed in the last decade. I will also provide some perspective on how new technologies have affected large information retrieval systems and what technologies will be required of such systems in the future, as the demands and requirements of large information retrieval systems continue to mature to meet increasing user needs.
