    Abstract
    Most information systems share a common assumption: information seeking is discrete. Such an assumption neither reflects real-life information seeking processes nor conforms to the perspective of phenomenology, "life is a journey constituted by continuous acquisition of knowledge." Thus, this study develops and validates a theoretical model that explains successive search experience for essentially the same information problem. The proposed model is called Multiple Information Seeking Episodes (MISE), which consists of four dimensions: problematic situation, information problem, information seeking process, episodes. Eight modes of multiple information seeking episodes are identified and specified with properties of the four dimensions of MISE. The results partially validate MISE by finding that the original MISE model is highly accurate, but less sufficient in characterizing successive searches; all factors in the MISE model are empirically confirmed, but new factors are identified as weIl. The revised MISE model is shifted from the user-centered to the interaction-centered perspective, taking into account factors of searcher, system, search activity, search context, information attainment, and information use activities.

    Abstract
    In this paper results of a field study into the need for research information of different user groups are presented: scientists, policy makers and policy researchers, industry and media. Main questions of semi-structured interviews were: what kind of research information users need, what kind of research information resources are used and which information resources are missing at the moment. User groups are missing for a diversity of reasons the overview of research, experts and institutes in the different scientific fields. Especially for the accessibility and transparency of the scientific world these overviews are reported to be needed. Neither Google nor any of the research institutes or policy research organisations are able to present surveys for different science fields at the moment. Giving users the possibility to search, browse and navigate through accessible and more specialised layers of research information might give answers to different user groups simultaneously.

    Abstract
    Keeping up to date with research developments is a central activity of academic researchers, but researchers face difficulties in managing the rapid growth of available scientific information. This study examined how researchers stay up to date, using the information journey model as a framework for analysis and investigating which dimensions influence information behaviors. We designed a 2-round study involving semistructured interviews and prototype testing with 61 researchers with 3 levels of seniority (PhD student to professor). Data were analyzed following a semistructured qualitative approach. Five key dimensions that influence information behaviors were identified: level of seniority, information sources, state of the project, level of familiarity, and how well defined the relevant community is. These dimensions are interrelated and their values determine the flow of the information journey. Across all levels of professional expertise, researchers used similar hard (formal) sources to access content, while soft (interpersonal) sources were used to filter information. An important "pain point" that future information tools should address is helping researchers filter information at the point of need.

    Abstract
    Research methodologies in several of the social sciences require the use of tests. When assisting social science researchers who seek information on tests, reference librarians do not, themselves, always have direct access to the instruments. Librarians should not only have the knowledge that various print and electronic database resources are available to gain needed information, but they should also have a strategy by which these sources can be searched in an expedient and thorough manner. This paper offers such a search strategy which can be used with the materials commonly found in a large research or specialized test library

    Abstract
    As a result of the Internet, electronic networks occupy a more visible place in everyday life. Until the early nineties, the use of electronic networks was limited to a rather small number of people working in enterprises and universities. Since then, the networks have become more accessible for other citizens. Currently at least 60-70 million people all over the world are estimated to use the Internet (Gaines et al., 1997: 990). In 2000, the number of WWW users alone is expected to reach 160 million (Aldridge & Darwood 1997: 283). The rapid growth of network use has given rise to a lot of research needs. For example, what are the main purposes of network use and to what extent may the Internet replace other channels in information seeking? Thus far, the utilization of networks has been mainly surveyed in the USA but, in recent years issues of use have also attracted increasing attention in Western Europe. This study is a continuation of a research project focusing on the ways in which citizens seek information in the context of everyday life (see Savolainen 1995). An attempt is made to analyze how citizens utilize the electronic networks, primarily for non-work purposes. This paper communicates part of an empirical study; a detailed report is available in Finnish (Savolainen 1998b).

    Abstract
    This article presents the research findings of a study on task complexity and information-seeking activities in real-life work tasks. The focus was on perceived task complexity, which was determined according to the task performers' prior knowledge about the task ahead. This view on task complexity is closely related to research considering task uncertainty and analyzability. Information-seeking activities considered were a need to acquire different types of information and the subsequent use of different types of sources. The research data were mainly collected by (1) self-recorded journals that were filled out by municipal administrators in the course of performing their ordinary work duties (altogether 78 task diaries), and (2) subsequent interviews. The results indicated that there is a relatively strong relationship between types of information and types of sources. The effects of task complexity made experts more attractive as a source than other people and all types of documentary sources.

    Abstract
    User studies provide libraries with invaluable insight into their users' information needs and behaviors, allowing them to develop services that correspond to these needs. This insight has become even more important for libraries since the advent of the Internet. The Internet has brought about a development of information technologies and electronic information sources that have had a great impact on both the ways users search for information and the ways libraries manage information. Although humanists represent an important group of users for academic libraries, research studies into their information-seeking behavior since the advent of the Internet have been quite scarce (Ellis & Oldman, 2005) in the past decade. This study presents updated research on a group of humanists, Jewish studies scholars living in Israel, as information users in the digital age based on two categories: (a) the use of formal and informal information channels, and (b) the use of information technologies and their impact on humanistic research.

    Abstract
    The information search process (ISP) is a six-stage model of the users' holistic experience in the process of information seeking. The ISP model, based on two decades of empirical research, identifies three realms of experience: the affective (feelings), the cognitive (thoughts), and the physical (actions) common to each stage. These studies were among the first to investigate the affective aspects or the feelings of a person in the process of information seeking along with the cognitive and physical aspects. Central to the ISP is the notion that uncertainty, both affective and cognitive, increases and decreases in the process of information seeking. A principle of uncertainty for information seeking is proposed that states that information commonly increases uncertainty in the early stages of the search process. Increased uncertainty indicates a zone of intervention for intermediaries and system designers.

    Abstract
    To better understand how individuals and groups derive satisfaction from information, it is important to identify the information source preferences they apply in information seeking and decision making. Four informal propositions drove the structure and underlying logic of this study, forming a preliminary outline of a theory of information source preference profiles and their influence an information satisfaction. This study employed Social Judgment Analysis (SJA) to identify the information judgment preferences held by professional groups for six selected information sources: word of mouth, expert oral advice, Internet, print news, nonfiction books, and radio/television news. The research was designed as an hypotheses-generating exploratory study employing a purposive sample (n = 90) and generated four empirically supported, testable hypotheses about user satisfaction with information sources. The SJA judgment functions revealed the influences of volume and polarity (i.e., positive versus negative information) an information satisfaction. By advancing the understanding of how information source preferences can be identified empirically and their influence an information satisfaction, this research reflects a first, small step toward understanding "satisficing." Satisficing behaviors result in early termination of information search processes when individuals, facing incomplete information, are sufficiently satisfied to assume risks and execute decisions.

    Abstract
    Past trends in reference instruction, query analysis and proloferation of reference tools classed by primary functions into a general typology anticipated the use of paradigm logic, templates, search strategies, and systematic searching in applied Artificial Intelligence research and design of expert system, especially referral and decision-support systems. The approach, methodologies, and technique employed in basic reference and subject-area reference instruction in four graduate library schools, developed first at the University of Maryland after 1976, are reviewed. The advantages and limitations of the latter are discussed to suggest the interplay of personal service, manual tools, and computerized systems for holistic reference programs. Librarians' transition to the automated tools using AI methods might be improved by introducing paradigms, typologies, strategies, and a systems approach in reference instruction for professionals and more generally in bibliographic instruction

    Abstract
    Previous studies have found that both (a) the characteristics (e.g., quality and accessibility) and (b) the types of sources (e.g., relational and nonrelational sources) influence information source selection. Different from earlier studies that have prioritized one source attribute over the other, this research uses information need as a contingency factor to examine information seekers' simultaneous consideration of different attributes. An empirical test from 149 employees' evaluations of eight information sources revealed that (a) low-and high-information-need individuals favored information source quality over accessibility while medium-information-need individuals favored accessibility over quality; and (b) individuals are more likely to choose relational over nonrelational sources as information need increases.

    Abstract
    Purpose - The purpose of this paper is to examine the information-seeking behavior of science and social science research scholars, including service effectiveness, satisfaction level on different type of sources and various methods adopted by the scholars for keeping up to date. Design/methodology/approach - Data were gathered using a questionnaire survey of 200, randomly selected, PhD students of science and social science departments of four universities in Kerala, India. Findings - Although similarities exist between social science and science PhD students with regard to information-seeking behavior, there are significant differences as well. There is a significant difference between science and social science scholars on the perception of the adequacy of print journals and database collection which are very relevant to the research purposes. There is no significant difference between science and social science scholars on the perception of the adequacy of e-journals, the most used source for keeping up to date. The study proved that scholars of both the fields are dissatisfied with the effectiveness of the library in keeping them up to date with latest developments. Originality/value - The study is based on actual situation and the result can be used for library service redesign for different types of users.

    Abstract
    This article investigates whether information seeking patterns can be related to discipline differences, study approaches, and personality traits. A quantitative study of 305 master's thesis students' information behavior found that their information seeking tended to be either exploratory or precise. Statistical analyses showed that inner traits seemed more influential than discipline characteristics an information behavior. Exploration or specificity was manifested in terms of both the level and scope of information students wished to retrieve and the way they searched for it.

    Abstract
    Successive information searches are fairly common. To enhance the understanding of the behavior, this study attempted to improve both the descriptive and explanatory power of the Multiple Information Seeking Episodes (MISE) model, a conceptual model characterizing factors affecting successive searches. It empirically observed how the key factors in the information seeking process in the MISE model evolve over multiple search sessions and explained how those factors are affected by other factors associated with searchers, search activity, search context, systems, information attainment, and information-use activities. The validated and enriched MISE model can be extended to serve the basis for future studies in other complex searches process such as multi-tasking and collaborative searches, and can also help identify problems that users face and thus derive requirements for system support.
