- Abstract
- Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths

- Abstract
- We are living in a society in which using Internet is a part of everyday life. People use Internet at schools, universities, at work in small and big companies. The Web gives huge number of information from every possible field of knowledge, and one of the problems that one can face by searching through the web is the fact that this information may be written in many different languages that one does not understand. That is why web site designers came up with an idea to create on-line dictionaries to make surfing on the Web easier. The most popular are bilingual dictionaries (in Poland the most known are: LING.pl, LEKSYKA.pl, and Dict.pl), but one can find also multilingual ones (Logos.com, Lexicool.com). Nowadays, when using Internet in education becomes more and more popular, on-line dictionaries are the best supplement for a good quality work. The purpose of this paper is to present, compare and recommend the best (from the author's point of view) multilingual dictionaries that can be found on the Internet and that can serve educational purposes well.

- Abstract
- Suggests techniques and evaluation criteria for information sources and services available on the Internet. The need for qualitative judgements about library materials and information sources is upheld and accepted techniques and evaluation criteria for printed reference works are outlines. The emergence of non-book materials and electronic information formats has created the need for new techniques and criteria relating specifically to online services and CD-ROM products. Use of the Internet by library and information workers is examined, establishing that the majority of current traffic is communications-based. The authors suggest that networked information sources require the development of additional techniques and criteria for evaluation if they are to be used by information professionals. The potential issues in establishing such a list are discussed

- Abstract
- Purpose This study continues a long history of author co-citation analysis of the intellectual structure of information science into the time period of 2011-2020. It also examines changes in this structure from 2006-2010 through 2011-2015 to 2016-2020. Results will contribute to a better understanding of the information science research field. Design/methodology/approach The well-established procedures and techniques for author co-citation analysis were followed. Full records of research articles in core information science journals published during 2011-2020 were retrieved and downloaded from the Web of Science database. About 150 most highly cited authors in each of the two five-year time periods were selected from this dataset to represent this field, and their co-citation counts were calculated. Each co-citation matrix was input into SPSS for factor analysis, and results were visualized in Pajek. Factors were interpreted as specialties and labeled upon an examination of articles written by authors who load primarily on each factor. Findings The two-camp structure of information science continued to be present clearly. Bibliometric indicators for research evaluation dominated the Knowledge Domain Analysis camp during both fivr-year time periods, whereas interactive information retrieval (IR) dominated the IR camp during 2011-2015 but shared dominance with information behavior during 2016-2020. Bridging between the two camps became increasingly weaker and was only provided by the scholarly communication specialty during 2016-2020. The IR systems specialty drifted further away from the IR camp. The information behavior specialty experienced a deep slump during 2011-2020 in its evolution process. Altmetrics grew to dominate the Webometrics specialty and brought it to a sharp increase during 2016-2020. Originality/value Author co-citation analysis (ACA) is effective in revealing intellectual structures of research fields. Most related studies used term-based methods to identify individual research topics but did not examine the interrelationships between these topics or the overall structure of the field. The few studies that did discuss the overall structure paid little attention to the effect of changes to the source journals on the results. The present study does not have these problems and continues the long history of benchmark contributions to a better understanding of the information science field using ACA.

- Abstract
- Reviews Gale's Ready Reference Shelf CD-ROM which enables library patrons to find their own information. Although this CD is marketed to libraries for patrons to do their own referencing, it is more appropriately used by librarians since it is an index to information sources, not the sources themselves. The CD gives Access to the following resources: Encyclopedia of Associations; Publishers Directory; Gale Directory of Publications and Broadcast Media; Directories in Print; Newsletters in Print; Gale Directory of Databases; Directory of Special Libraries; Research Centres Directory; and the Encyclopedia of American Religions. The software allows a number of sources to be searches simultaneously. Discusses quick searches; extended searches; the command line expert search; and compares the product with Microsoft's Bookshelf which contains a dictionary, almanac, thesaurus, basic encyclopedia and related material

- Abstract
- Purpose Wikipedia has the lofty goal of compiling all human knowledge. The purpose of the present study is to map the structure of the Traditional Chinese Medicine (TCM) knowledge domain on Wikipedia, to identify patterns of knowledge representation on Wikipedia and to test the applicability of author bibliographic coupling analysis, an effective method for mapping knowledge domains represented in published scholarly documents, for Wikipedia data. Design/methodology/approach We adapted and followed the well-established procedures and techniques for author bibliographic coupling analysis (ABCA). Instead of bibliographic data from a citation database, we used all articles on TCM downloaded from the English version of Wikipedia as our dataset. An author bibliographic coupling network was calculated and then factor analyzed using SPSS. Factor analysis results were visualized. Factors were labeled upon manual examination of articles that authors who load primarily in each factor have significantly contributed references to. Clear factors were interpreted as topics. Findings Seven TCM topic areas are represented on Wikipedia, among which Acupuncture-related practices, Falun Gong and Herbal Medicine attracted the most significant contributors to TCM. Acupuncture and Qi Gong have the most connections to the TCM knowledge domain and also serve as bridges for other topics to connect to the domain. Herbal medicine is weakly linked to and non-herbal medicine is isolated from the rest of the TCM knowledge domain. It appears that specific topics are represented well on Wikipedia but their conceptual connections are not. ABCA is effective for mapping knowledge domains on Wikipedia but document-based bibliographic coupling analysis is not. Originality/value Given the prominent position of Wikipedia for both information users and for researchers on knowledge organization and information retrieval, it is important to study how well knowledge is represented and structured on Wikipedia. Such studies appear largely missing although studies from different perspectives both about Wikipedia and using Wikipedia as data are abundant. Author bibliographic coupling analysis is effective for mapping knowledge domains represented in published scholarly documents but has never been applied to mapping knowledge domains represented on Wikipedia.

- Abstract
- For laypeople, searching online health information resources can be challenging due to topic complexity and the large number of online sources with differing quality. The goal of this article is to examine, among all the available online sources, which online sources laypeople select to address their health-related information needs, and whether or how much the severity of a health condition influences their selection. Twenty-four participants were recruited individually, and each was asked (using a retrieval system called HIS) to search for information regarding a severe health condition and a mild health condition, respectively. The selected online health information sources were automatically captured by the HIS system and classified at both the website and webpage levels. Participants' selection behavior patterns were then plotted across the whole information-seeking process. Our results demonstrate that laypeople's source selection fluctuates during the health information-seeking process, and also varies by the severity of health conditions. This study reveals laypeople's real usage of different types of online health information sources, and engenders implications to the design of search engines, as well as the development of health literacy programs.

- Abstract
- Describes the advantages of CD-ROMs over printed and on-line sources: large storage capacity, relative cheapness and minimum instruction required to undertake searches. Identifies 5 main criteria from the literature which should be considered when introducing this technology into reference libraries. Cost, currency and contents should be considered when comparing their usefulness with other media. At present, CD-ROMs offer the most efficient service when used in conjunction with both printed and on-line media

- Abstract
- A unique collection of historical material covering the lives and events of an English village between 1400 and 1750 has been made available via a WWW enabled information retrieval system. Since the expected readership of the documents ranges from school children to experienced researchers, providing this information in an easily accessible form has offered many challenges requiring tools to aid searching and browsing. The file structure of the document collection was replaced by an database, enabling query results to be presented on the fly. A Java interface displays each user's context in a form that allows for easy and intuitive relevance feedback

- Abstract
- Using the Arts & Humanities Citation Index (A&HCI) 2008, we apply mapping techniques previously developed for mapping journal structures in the Science and Social Sciences Citation Indices. Citation relations among the 110,718 records were aggregated at the level of 1,157 journals specific to the A&HCI, and the journal structures are questioned on whether a cognitive structure can be reconstructed and visualized. Both cosine-normalization (bottom up) and factor analysis (top down) suggest a division into approximately 12 subsets. The relations among these subsets are explored using various visualization techniques. However, we were not able to retrieve this structure using the Institute for Scientific Information Subject Categories, including the 25 categories that are specific to the A&HCI. We discuss options for validation such as against the categories of the Humanities Indicators of the American Academy of Arts and Sciences, the panel structure of the European Reference Index for the Humanities, and compare our results with the curriculum organization of the Humanities Section of the College of Letters and Sciences of the University of California at Los Angeles as an example of institutional organization.

- Extends the WWW hypertext search paradigm to allow flexible conceptual navigation of online databases. Using the WWW Common Gateway Interface standard and natural language processing techniques. The WEBLINE Virtual Hypertext Saerch interface prototype automatically identifies noun phrases in retrieved records and it converts them into dynamic hotlinks and search strategies to support associative hypertext browsing of MEDLINE and other NLM databases. The approach is applicable to the searching of online databases in general and can be broadened to implement virtual hypertext searching of the Virtual WWW

- Abstract
- While there are many information sources available on the WWW, the identification of significant Internet resources is often not as efficient nor as effective as many would desire. In 1995, a demonstration prototype service, CyberStacks, was established at Iowa State University to enhance access and use of selected Internet resources in science, technology and related areas through the application of the LCC as an organization framework. reviews the creation of CyberStacks and the methods and techniques for facilitating access to WWW resources

- Abstract
- Despite the development of huge healthcare Web sites and powerful search engines, many searchers end their searches prematurely with incomplete information. Recent studies suggest that users often retrieve incomplete information because of the complex scatter of relevant facts about a topic across Web pages. However, little is understood about regularities underlying such information scatter. To probe regularities within the scatter of facts across Web pages, this article presents the results of two analyses: (a) a cluster analysis of Web pages that reveals the existence of three page clusters that vary in information density and (b) a content analysis that suggests the role each of the above-mentioned page clusters play in providing comprehensive information. These results provide implications for the design of Web sites, search tools, and training to help users find comprehensive information about a topic and for a hypothesis describing the underlying mechanisms causing the scatter. We conclude by briefly discussing how the analysis of information scatter, at the granularity of facts, complements existing theories of information-seeking behavior.
