Abstract

Key terms related to information searching and search models are defined. A historic context is provided to illustrate the evolution of the four main digital environments that users interact with in their search process to offer readers background information regarding the transition from manual information systems to computer-based information retrieval (IR) systems, as well as the transition from intermediary searching to end-user searching. Emphasis is placed on the review of different levels of information searching from search tactics/moves, search strategies, and usage patterns, to search models and associated factors in relation to task, user knowledge structure, IR system design, and social-organization context. Search models are further classified into two types, with one type illustrating information search process (ISP) and the other type emphasizing the factors that influence the process. In addition, unsolved problems and future research are discussed and suggested.

Abstract

The field of human information behavior runs the gamut of processes from the realization of a need or gap in understanding, to the search for information from one or more sources to fill that gap, to the use of that information to complete a task at hand or to satisfy a curiosity, as well as other behaviors such as avoiding information or finding information serendipitously. Designers of mechanisms, tools, and computer-based systems to facilitate this seeking and search process often lack a full knowledge of the context surrounding the search. This context may vary depending on the job or role of the person; individual characteristics such as personality, domain knowledge, age, gender, perception of self, etc.; the task at hand; the source and the channel and their degree of accessibility and usability; and the relationship that the seeker shares with the source. Yet researchers have yet to agree on what context really means. While there have been various research studies incorporating context, and biennial conferences on context in information behavior, there lacks a clear definition of what context is, what its boundaries are, and what elements and variables comprise context. In this book, we look at the many definitions of and the theoretical and empirical studies on context, and I attempt to map the conceptual space of context in information behavior. I propose theoretical frameworks to map the boundaries, elements, and variables of context. I then discuss how to incorporate these frameworks and variables in the design of research studies on context. We then arrive at a unified definition of context. This book should provide designers of search systems a better understanding of context as they seek to meet the needs and demands of information seekers. It will be an important resource for researchers in Library and Information Science, especially doctoral students looking for one resource that covers an exhaustive range of the most current literature related to context, the best selection of classics, and a synthesis of these into theoretical frameworks and a unified definition. The book should help to move forward research in the field by clarifying the elements, variables, and views that are pertinent. In particular, the list of elements to be considered, and the variables associated with each element will be extremely useful to researchers wanting to include the influences of context in their studies.

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

With the establishment of the WWW as a standard information tool in academic libraries, there is a greater demand for research assistance than ever before. Reference questions involve more teaching time given the number of interfaces clients confront as they navigate the book catalogue, electronic databases, and the WWW. Librarians require expert knowledge of multiple search strategies as well as the ability to teach others how to apply them effectively. Outlines hoe the WWW can function as a desktop publishing system, revitalize subject pathfinders and 'how to' guides, and promote the invention of interactive library tutorials. A Web site presenting design ideas accompanies this article at: http://stauffer.queensu.ca/inforef/tutorials/cla/clahome.htm

Abstract

Purpose - This study provides evidence on the actual information-seeking behaviour of students in a digital scholarly environment, not what they thought they did. It also compares student information-seeking behaviour with that of other academic communities, and, in some cases, for practitioners. Design/methodology/approach - Data were gathered as part of CIBER's ongoing Virtual Scholar programme. In particular log data from two digital journals libraries, Blackwell Synergy and OhioLINK, and one e-book collection (Oxford Scholarship Online) are utilized. Findings - The study showed a distinctive form of information-seeking behaviour associated with students and differences between them and other members of the academic community. For example, students constituted the biggest users in terms of sessions and pages viewed, and they were more likely to undertake longer online sessions. Undergraduates and postgraduates were the most likely users of library links to access scholarly databases, suggesting an important "hot link" role for libraries. Originality/value - Few studies have focused on the actual (rather than perceived) information-seeking behaviour of students. The study fills that gap.

Rez. in: JASIST 58(2007) no.2, S.303-305 (L. Hayden): "Part history and part call to action, Covert and Overt examines the relationship between the disciplines of intelligence service and information science. The book is significant in that it captures both the rich history of partnership between the fields, and because it demonstrates clearly the incomplete nature of our understanding of that partnership. In the post-9/11 world, such understanding is increasingly important, as we struggle with the problem of transforming information into intelligence and intelligence into effective policy. Information science has an important role to play in meeting these challenges, but the sometimesambiguous nature of the field combined with similar uncertainties over what constitutes intelligence, makes any attempt at definitive answers problematic. The book is a collection of works from different contributors, in the words of one editor "not so much a created work as an aggregation" (p. 1). More than just an edited collection of papers, the book draws from the personal experiences of several prominent information scientists who also served as intelligence professionals from World War II onward. The result is a book that feels very personal and at times impassioned. The contributors attempt to shed light on an often-closed community of practice, a discipline that depends simultaneously on access to information and on secrecy. Intelligence, like information science, is also a discipline that finds itself increasingly attracted to and dependent upon technology, and an underlying question of the book is where and how technology benefits intelligence (as opposed to only masking more fundamental problems of process and analysis and providing little or no actual value).
The role of technology in both intelligence and information science is just one question explored in Covert and Overt, which takes on more fundamental issues as well. Even the ubiquitous "What is information?" debate is revisited. But the questions asked are always subordinate to the overarching theme of bringing concepts and techniques of intelligence and information science together and examining the results. The process and lifecycle of intelligence is explored and mapped to information science methods, primarily indexing and information retrieval. In more historical explorations undertaken by contributors, it becomes apparent that intelligence and information science have always been closely aligned, but that this alignment is not always perceived by those engaged in intelligence work. Interestingly, and probably not surprisingly, a general consensus seems to be that library and information science practitioners involved in intelligence were (and are) more capable of seeing the complementary nature of the techniques information science brings to intelligence services than many intelligence professionals, who often needed demonstrations of efficacy to be convinced. Structurally, the book is divided into four parts, moving from anecdotal accounts through to discussions of definition and theory. Part 1, "Information Science and Intelligence: Reminiscences and Reflections from World War II to Today" is comprised of the personal stories of information scientists who also served as intelligence professionals at various times during and since World War II, collected from special panel presentations at the 2001 and 2002 American Society for Information Science and Technology (ASIS&T) annual conferences. These contributors include former American and British servicemen and intelligence officers who all relate a common experience of dealing with information, documents, and other records in the pursuit of intelligence goals.
This book is a successful and realistic examination of the current state of inquiry into the relationship between intelligence and information science, and does not flinch from the limits of this inquiry to date. The book can be viewed as a deliberate attempt to stimulate further interest in these studies, and serves as an excellent roadmap for future researchers (like this reviewer) who also have moved from intelligence service into information science. Many of the stories and studies in the book could easily provide fresh and vital avenues of research to new and veteran scholars. If there are limitations to the impact of the book, most must be viewed in the context of the lack of literature from which to draw. Contributions come from a variety of sources and although some new studies are included, for the most part, the chapters are not original to this publication. This results at times in a sense of the editors taking what they could get on the topic. The reader must determine whether this is viewed as a flaw or as reinforcement of the editors' conclusion that more research into the subject matter is important and necessary. It becomes a question of whether or not one wishes to answer the call. One interesting limitation, however, is the lack of a critical stance on the part of most of the contributors. The chapters tend to describe the relationship between intelligence and information science, but few question the nature of that relationship, the social construction of the two disciplines, or moral and ethical concerns associated with spying and information operations. In general, a reader is left with the impression that intelligence service is a good thing, and that information science as a discipline can both improve it as well as learn from it. Little insight is offered into the value and direction of intelligence in the 21 st century, or the impact that our technologies may have. One exception comes from Colin Burke who, in his chapter, "Intelligence Agencies, Librarians, and Information Scientists," touches on some of these issues with his claim that library and information science practitioners must "help bring the information advances from the intelligence communities to an industry that can be committed to distributing information at the lowest cost to the most people" (p. 112). Nevertheless, no serious questions regarding issues of control, power, or resistance are raised. Given recent debates over surveillance, privacy, and the erosion of civil liberties in the wake of 9-11, it would seem that this is an area of intelligence and information studies that also deserves attention. Covert and Overt is an excellent historical overview of the close relationship between intelligence and information science. The book is also intriguing and timely in its argument for further research and study into these areas. Despite the limitations of subject matter and the challenges that come with the disciplines that it explores, it is required reading for practitioners in either world who wish to gain a greater understanding of the operations of the other."

Abstract

Design/methodology/approach An operationalisation of the model is presented based on the theory of expectancy-value and on the operationalisation used when the model was first developed. Data for the analysis were collected from a sample of seven informants working as consultants in Danish municipalities. Each participant filled out a questionnaire, kept a log book for a week and participated in a subsequent interview to elicit data regarding their information source behaviour and task motivation. Findings Motivation affected source use when the informants search for information as part of their professional life. This meant that the number of sources used and the preference for interpersonal and internal sources increased when the task had high-value motivation or low-expectancy motivation or both. Research limitations/implications The study is based on a relatively small sample and considers only one motivation theory. This should be addressed in future research along with a broadening of the studied group to involve other professions than municipality consultants. Originality/value Motivational theories from the field of psychology have been used sparsely in studies of information seeking. This study operationalises and verifies such a theory based on a theoretical adaptation of this model made by Savolainen (2012c).

Rez. in: JASIST 58(2007) no.3, S.456-457 (D. Cook): "In February 2006, the Educational Testing Service (ETS) announced the release of its brand new core academic assessment of its Information and Communication Technology (ICT) Literacy Assessment. The core assessment is designed to assess the information literacy of high school students transitioning to higher education. Many of us already know ETS for some of its other assessment tools like the SAT and GRE. But ETS's latest test comes on the heels of its 2005 release of an advanced level of its ICT Literacy Assessment for college students progressing to their junior and senior year of undergraduate studies. Neither test, ETS insists, is designed to be an entrance examination. Rather, they are packaged and promoted as diagnostic assessments. We are in the grips of the Information Age where information literacy is a prized skill. Knowledge is power. However, information literacy is not merely creating flawless documents or slick PowerPoint presentations on a home PC. It is more than being able to send photos and text messages via cell phone. Instead, information literacy is gauged by one's ability to skillfully seek, access, and retrieve valid information from credible and reliable sources and using that information appropriately. It involves strong online search strategies and advanced critical thinking skills. And, although it is not clear whether they seized the opportunity or inherited it by default, librarians are in the vanguard of teaching information literacy to the next generation of would-be power brokers.
The release of Stimulated Recall and Mental Models, therefore, could not have been timelier. It describes an empirical qualitative, case study research conducted by authors Lyn Henderson and Julie Tallman in which they studied the mental models of school librarians teaching K-12 students how to use electronic databases. In this research, funded by the Spencer Foundation, Henderson and Tallman studied and analyzed the mental models of their subjects, six American and four Australian school librarians, as they went about the task of teaching students one-on-one how to access and retrieve the information they needed for class assignments from electronic databases. Each librarian and student underwent a structured pre-lesson interview to ascertain their mental models (the sum of their prior learning and experiences) regarding the upcoming lesson. The lesson followed immediately and was carefully video- and audio-recorded, with the full knowledge of the librarian and her student. After the lessons, both student and librarian were interviewed with the intent of learning what each were thinking and feeling at specific points during the lesson, using the recordings as memory joggers. After the first librarian-pupil session, the student was freed but the librarian was re-studied tutoring a second learner. Again, the teacher and new student were preinterviewed, their lesson was recorded, and they were debriefed using the recordings for stimulated recall. It is important to note here the use of the recordings to create stimulated recall. Though considered a dubious practice by many respected researchers, Henderson and Tallman expend considerable time and effort in this book trying to establish the credibility of stimulated recall as a valid research tool. I find it interesting that the authors report that their realization of the value of stimulated recall was a collateral benefit of their study; they claim the original objective of their research was to analyze and compare the pre- and post-lesson mental models of the teacher-librarians (p.15). Apparently, this realization provided the inspiration for this book (pp. I & 208). Hence, its place of importance in the book's title.
This book is evidence that Henderson and Tallman were meticulous in following their established protocols and especially in their record keeping while conducting their research. There are, however, a few issues in the study's framework and methodology that are worth noting. First, although the research was conducted in two different countries - the United Slates and Australia - it is not clear from the writing if the librarian-pupil pairs of each country hailed from the same schools (making the population opportunistic) or if the sampling was indeed more randomly selected. Readers do know, though, that the librarians were free to select the students they tutored from within their respective schools. Thus, there appears to he no randomness. Second, "[t]he data collection tools and questionnaires were grounded in a [single] pilot study with a [single] teacher-Iibrarian" (p. 7). Neither the procedures used nor the data collected from the pilot study are presented to establish its reliability and validity. Therefore, readers are left with only limited confidence in the study's instrumentation. Further, it is obvious from the reading, and admitted by the researchers, that the recording equipment in open view of the study's subjects skewed the data. That is, one of the librarians tinder study confessed that were it not for the cameras, she would have completely deserted one of her lessons when encountering what she perceived to be overwhelming obstacles: a classic example of the Hawthorne Effect in research. Yet. despite these issues, researchers Henderson and Tallman make a respectable ease in this book for the validity of both mental models and stimulated recall. The mental models developed during the prelesson interviews seem remarkably accurate when observing the school librarians during the lessons. Additionally, while the librarians were able to adapt their lessons based on situations, they generally did so within their mental models of what constitutes good teachers and good teaching.
As for the value of reflecting on their teaching performance, the authors report the not-so-startling denouement that while it is easy to identify and define malpractice and to commit to changing performance errors, it is often difficult to actually implement those improvements. Essentially, what is first learned is best learned and what is most used is best used. In the end, however, the authors rightfully call for further study to be conducted by themselves and others. ETS's core ICT Literacy Assessment is not currently a mandatory college entrance examination. Neither is the advanced ICT Literacy Assessment a mandatory examination for promotion to upper level undergraduate studies. But it would be naïve not to expect some enterprising institutions of higher education to at least consider making them so in the very near future. Consequently, librarians of all stripes (public. academic, school, or others) would do well to read and study Stimulated Recall and Mental Models if they are truly committed to leading the charge on advancing information literacy in the Information Age. In this book are some valuable how-tos for instructing patrons on searching electronic databases. And some of those same principles could be applicable to other areas of information literacy instruction."

Aus der Analyse des Ist-Zustands wird der Bedarf an Enterprise-Search-Software abgeleitet und es werden Rahmenbedingungen für deren erfolgreiche Einführung skizziert. Die Untersuchung stützt sich auf eine im Jahr 2009 durchgeführte Onlinebefragung von 469 österreichischen Großunternehmen (Rücklauf 22 %) und daran anschließende Leitfadeninterviews mit zwölf Teilnehmern der Onlinebefragung. Der theoretische Teil verortet die Arbeit im Kontext des Informations- und Wissensmanagements. Der Fokus liegt auf dem Ansatz der Enterprise Search, ihrer Abgrenzung gegenüber der Suche im Internet und ihrem Leistungsspektrum. Im empirischen Teil wird zunächst aufgezeigt, wie die Unternehmen ihre Informationen organisieren und welche Probleme dabei auftreten. Es folgt eine Analyse des Status quo der Informati-onssuche im Unternehmen. Abschließend werden Bekanntheit und Einsatz von Enterprise-Search-Software in der Zielgruppe untersucht sowie für die Einführung dieser Software nötige Rahmenbedingungen benannt. Defizite machen die Befragten insbesondere im Hinblick auf die übergreifende Suche im Unternehmen und die Suche nach Kompetenzträgern aus. Hier werden Lücken im Wissensmanagement offenbar. 29 % der Respondenten der Onlinebefragung geben zu-dem an, dass es in ihren Unternehmen gelegentlich bis häufig zu Fehlentscheidungen infolge defizitärer Informationslagen kommt. Enterprise-Search-Software kommt in 17 % der Unternehmen, die sich an der Onlinebefragung beteiligten, zum Einsatz. Die durch Enterprise-Search-Software bewirkten Veränderungen werden grundsätzlich posi-tiv beurteilt. Alles in allem zeigen die Ergebnisse, dass Enterprise-Search-Strategien nur Erfolg haben können, wenn man sie in umfassende Maßnahmen des Informations- und Wissensmanagements einbettet.

Abstract

Human information interaction (HII) is an emerging area of study that investigates how people interact with information; its subfield human information behavior (HIB) is a flourishing, active discipline. Yet despite their obvious relevance to the design of information systems, these research areas have had almost no impact on systems design. One issue may be the contextual complexity of human interaction with information; another may be the difficulty in translating real-life and unstructured HII complexity into formal, linear structures necessary for systems design. In this book, Raya Fidel proposes a research approach that bridges the study of human information interaction and the design of information systems: cognitive work analysis (CWA). Developed by Jens Rasmussen and his colleagues, CWA embraces complexity and provides a conceptual framework and analytical tools that can harness it to create design requirements. CWA offers an ecological approach to design, analyzing the forces in the environment that shape human interaction with information. Fidel reviews research in HIB, focusing on its contribution to systems design, and then presents the CWA framework. She shows that CWA, with its ecological approach, can be used to overcome design challenges and lead to the development of effective systems. Researchers and designers who use CWA can increase the diversity of their analytical tools, providing them with an alternative approach when they plan research and design projects. The CWA framework enables a collaboration between design and HII that can create information systems tailored to fit human lives. Human Information Interaction constructs an elegant argument for an ecological approach to information behavior. Professor Raya Fidel's cogent exposition of foundational theoretical concepts including cognitive work analysis delivers thoughtful guidance for future work in information interaction. Raya Fidel provides the human information interaction field with a manifesto for studying human information behavior from a holistic perspective, arguing that context dominates human action and we are obligated to study it. She provides a tutorial on cognitive work analysis as a technique for such study. This book is an important contribution to the Information field. Raya Fidel presents a nuanced picture of research on human information interaction, and advocates for Cognitive Work Analysis as the holistic approach to the study and evaluation of human information interaction.

Abstract

Describes the variety of search services supporting library reference functions offered by the RLG in the USA. The best known of these is RLIN, the massive bibliographic database and related services originally developed for shared cataloguing. In the last few years RLG has added CitaDel, an online search system that provides access to indexing/abstracting databases; and Zephyr, a Z39.50 server that amkes the RLIN and CitaDel databases searchable through a library's online catalogue. RLG also offers document delivery connections, including Ariel and Internet based document delivery software, for a full complement of online reference support for academic and public libraries

Abstract

This article focuses an analysing students' information needs in terms of conceptual understanding of the topic they propose to study and its consequences for the search process and outcome. The research subjects were 22 undergraduates of psychology attending a seminar for preparing a research proposal for a small empirical study. They were asked to make searches in the PsycINFO database for their task in the beginning and end of the seminar. A pre- and postsearch 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 during the preparation of research proposals different features of the students' conceptual structure were connected to the search success. Students' ability to cover their conceptual construct by query terms was the major feature affecting search success during the whole process. In the beginning also the number of concepts and the proportion of subconcepts in the construct contributed indirectly via search tactics to retrieving partly useful references. Students' ability to extract new query terms from retrieved items improved search results.

Abstract

Almost 30 years ago, Taylor (1968) postulated that each information need moves along a continuum from the visceral need through the compromised need. The current study examines the final transition in this continuum: from formalized need (expressed in an explicit verbal statement) to compromised need (represented in the language of the retrieval system). This transition is primarily concerned with vocabulary: the searcher attempts to translate an explicit statement of need into a search term (or terms) that can be interpreted by the retrieval system. A few studies have empirically examined the match between the end-user searcher's formalized need and the compromised need (i.e., search terms). Markey (1984) compared the searcher's expressed topic (the formalized need, expressed in just a few words) and the search terms (the compromised need), and then went on to compare the search terms with the library catalog terms available for subject searching. She found that the search term matched or was a partial form of the expressed topic in 71% of the searches, and that over 75% of these searches matched a catalog term. Allen (1991) examined the relationship between logical reasoning ability and selection of search terms. He asked college students to read a magazine article (which could be seen as a very rich statement of the formalized need) and then to perform a search for articles on the same topic (expressing the compromised need).

Abstract

A comprehensive discussion, with particular focus on procedures for organizing the collection (use of UDC and variation); factors involved in selection (Type of material, format, content); selection sources (details of general and specialized bibliographies covering book and non-book materials); weeding (criteria in relation to user and institutional needs); acquisition (legal deposit, donation, exchange, purchase); library suppliers (Choosing a service, ordering); collection evaluation (Quantitative and qualitative); service evaluation (statistics and reports)
