    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
    In a world of increasing information and communications possibilities, the difficulty for users of information systems and services may not lie in finding information but in filtering and integrating it into a cohesive whole. To do this, information seekers must know when and how to effectively use cognitive strategies to regulate their own thinking, motivation, and actions. Sometimes this is difficult when the topic is interesting and one is driven to explore it in great depth. This article reports on a qualitative study that, in the course of exploring the thinking and emotions of 10 adolescents during the information search process, uncovered patterns of behavior that are related to curiosity and interest. The larger purpose of the study was to investigate the metacognitive knowledge of adolescents, ages 16-18, as they searched for, selected, and used information to complete a school-based information task. The study found that the curiosity experienced by adolescents during the search process was accompanied by feelings of both pleasure and pain and that both feelings needed to be managed in order to navigate a pathway through the search process. The self-regulation of curiosity and interest was a clear and distinct metacognitive strategy fueled by metacognitive knowledge related to understanding one's own curiosity and the emotions attached to it.

    Abstract
    Researchers in the discipline of Higher Education have examined philosophical and psychological literature to develop epistemological development theories and models. They are primarily interested in understanding: "how individuals come to know, the theories and beliefs they hold about knowing, and the manner in which such epistemological premises are a part of and an influence on the cognitive processes of thinking and reasoning" (Hofer & Pintrinch, 1997). I propose to develop a theoretical framework for undergraduates' information seeking behavior based upon the insights into their knowledge construction offered through these models and theories of epistemological development. Epistemology is defined as "the philosophical study of the nature, sources, and limits of knowledge' (Moser, Mulder, & Trout, 1998). I will focus my paper on four major theories and models of undergraduates' epistemological development. I will present a new model of information seeking behavior incorporating these theories and models about how undergraduates construct knowledge and the consequent influence on their information seeking behavior

    Abstract
    This study is based an earlier research by the author that employed social judgment analysis (SJA; J. SteflMabry, 2001, 2003) to identify the information judgment preferences held by professional groups. This study explores the extent to which individuals, professional groups, and subgroups are self-aware of their judgment profiles. Three specialized groups of professionals-law enforcement, medicine, and education-were chosen to determine if preference profiles cluster around professions or around demographic and other background variables. As the proliferation of data continues to increase, the need to understand users' media preference and selection decisions is of tremendous value to every industry, governmental agency, and institution of learning. In 1966, H. Menzel first raised concern about the reliability of users' to self-assess, and scientists continue to explore the issue of competency in human judgment. To understand the reliability of users' self-assessment regarding media preferences, this study examines the extent to which individuals and groups are self-aware of the empirical judgment profiles they employ in evaluating information source scenarios. This investigation explores the congruence of three groups of professionals' self-reported media preferences as compared to their empirical judgment values, as defined by social judgment analysis.

    Abstract
    Information searching in practice seldom is an end in itself. In work, work task (WT) performance forms the context, which information searching should serve. Therefore, information retrieval (IR) systems development/evaluation should take the WT context into account. The present paper analyzes how WT features: task complexity and task types, affect information searching in authentic work: the types of information needs, search processes, and search media. We collected data on 22 information professionals in authentic work situations in three organization types: city administration, universities, and companies. The data comprise 286 WTs and 420 search tasks (STs). The data include transaction logs, video recordings, daily questionnaires, interviews. and observation. The data were analyzed quantitatively. Even if the participants used a range of search media, most STs were simple throughout the data, and up to 42% of WTs did not include searching. WT's effects on STs are not straightforward: different WT types react differently to WT complexity. Due to the simplicity of authentic searching, the WT/ST types in interactive IR experiments should be reconsidered.

    Abstract
    The study analyses how students' growing understanding of the topic and search experience were related to their choice of search tactics and terms while preparing a research proposal for a small empirical study. In addition to that, the findings of the study are used to test Vakkari's (2001) theory of task-based IR. The research subjects were 22 students of psychology attending a seminar for preparing the proposal. They made a search for their task in PsychINFO database at the beginning and end of the seminar. Data were collected in several ways. A pre- and post-search interview was conducted in both sessions. The students were asked to think aloud in the sessions. This was recorded as were the transaction logs. The results show that search experience was slightly related to the change of facets. Although the students' vocabulary of the topic grew generating an increased use of specific terms between the sessions, their use of search tactics and operators remained fairly constant. There was no correlation between the terms and tactics used and the total number of useful references found. By comparing these results with the findings of relevant earlier studies the conclusion was drawn that domain knowledge has an impact on searching assuming that users have a sufficient command of the system used. This implies that the tested theory of task-based IR is valid on condition that the searchers are experienced. It is suggested that the theory should be enriched by including search experience in its scope.
