- Abstract
- The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized

- Abstract
- Since their inception in the early 1960s the strength and unique aspect of the ISI citation indexes has been their ability to illustrate the conceptual relationships between scholarly documents. When authors create reference lists for their papers, they make explicit links between their own, current work and the prior work of others. The exact nature of these links may not be expressed in the references themselves, and the motivation behind them may vary (this has been the subject of much discussion over the years), but the links embodied in references do exist. Over the past 30+ years, technology has allowed ISI to make the presentation of citation searching increasingly accessible to users of our products. Citation searching and link tracking moved from being rather cumbersome in print, to being direct and efficient (albeit non-intuitive) online, to being somewhat more user-friendly in CD format. But it is the confluence of the hypertext link and development of Web browsers that has enabled us to present to users a new form of citation product -- the Web of Science -- that is intuitive and makes citation indexing conceptually accessible. A cited reference search begins with a known, important (or at least relevant) document used as the search term. The search allows one to identify subsequent articles that have cited that document. This feature adds the dimension of prospective searching to the usual retrospective searching that all bibliographic indexes provide. Citation indexing is a prime example of a concept before its time - important enough to be used in the meantime by those sufficiently motivated, but just waiting for the right technology to come along to expand its use. While it was possible to follow citation links in earlier citation index formats, this required a level of effort on the part of users that was often just too much to ask of the casual user. In the citation indexes as presented in the Web of Science, the relationship between citing and cited documents is evident to users, and a click of the mouse is all it takes to follow a citation link. Citation connections are established between the published papers being indexed from the 8,000+ journals ISI covers and the items their reference lists contain during the data capture process. It is the standardized capture of each of the references included with these documents that enables us to provide the citation searching feature in all the citation index formats, as well as both internal and external links in the Web of Science.

- Abstract
- All types of information can be referenced to a geographic place. Maps, aerial photographs, and remote sensing images are spatially georeferenced. Other forms of information such as books, articles, research papers, pieces of music, and art are often linked to a geographic location through place names (geographic names). A gazetteer (a dictionary of geographic names) that is spatially referenced itself provides the bridge between these two types of georeferencing. With a georeferenced gazetteer translation service, a user can start with a geographic name and find information that is described with either geographic names or with geospatial coordinates. Use of this powerful indirect geospatially referencing tool can be applied as a common approach to libraries, bibliographic files, data centers, web resources, and museum and specimen collections and can be particular useful across language barriers since latitude and longitude coordinates are universally understood. The Alexandria Digital Library has implemented a gazetteer component for its georeferenced digital library. This experience resulted in the creation of a Gazetteer Content Standard, a Feature Type Thesaurus, and an operational interactive gazetteer service. This paper describes the development of these components and illustrates the use of this tool in a georeferenced digital library. It also relates progress in working with Federal agencies and others toward developing shareable gazetteer data through Digital Gazetteer Information Exchange programs

- Abstract
- 'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

- Footnote
- Part 1, "Tools and Strategies," contains three chapters. The first is a very interesting one an the culture of mathematics. For undergraduates who are thinking about advanced study (or for friends and family who are puzzled about what a mathematician does), this is a concise and even elegant overview. "Tools" continues with chapters an "Finding Mathematics Information" and an "Searching the Research Literature." Both chapters are written by experienced mathematics librarians and answer questions asked by those learning and studying mathematics. "Finding Mathematics Information" contains sixteen sections (too many to enumerate)-two of our favorites are "Locating Definitions and Basic Explanations" and "Finding or Verifying Quotations and Anecdotes." As with Part II, each entry contains complete bibliographic information with a one- or twosentence abstract. "Searching the Research Literature" contains five sections: introduction, strategies, finding journal articles using indexes, finding papers an the Web, and obtaining the resources found. This chapter is more of a discussion than a list of resources, but like the chapter an "Finding Mathematics Information" would be helpful for someone just beginning research in mathematics. Because this work is primarily arranged by discipline, it offers a different perspective than Nancy D. Anderson and Lois M. Pausch, editors, A Guide to Library Service in Mathematics (Greenwich, CT: JAI Press, Inc.), 1993. One might also consult the $65 book by Martha Tucker and Nancy Anderson, Guide to Information Sources in Mathematics and Statistics (Westport, CT: Libraries Unlimited), 2004. The book's major drawback is its price - 42c per page vs. 19c for Tucker and Anderson. However, it is still an important addition to your library's collection, a relevant resource for undergraduate and graduate student advisors, and perhaps a gift for the new librarian who will be working with your department."

- 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

- Rez. in: JASIST 55(2004) no.7, S.651-652 (D.G. Smith): "A complex myriad of online information sources and services are currently accessible to knowledge workers worldwide. Those who have a computer equipped with a modern or Internet access can avail themselves of bibliographic, scientific, and full-text databases in a staggering number of disciplines. These online services, fueled by technological advancement, are in a constant state of change. Innovation occurs so quickly that it is difficult for knowledge workers to remember any other technological reality but the present. In such an environment, the origin of online information services often goes unconsidered. A History of Online Information Services, 1963-1976, by Charles P. Bourne and Trudi Bellardo Hahn, sheds light an the pioneering efforts of those who made current online information services possible. Michael Buckland states in the book's foreword that Bourne and Hahn's volume is the first history of the early online years. It covers the appearance of the first online information retrieval system in 1963 and concludes during 1976 when several commercial online information services, including DIALOG and LEXIS, became forerunners in the nascent online industry. Although developments in computing technology and communication networks were important to early online efforts, these topics are not discussed in the book. However, there are cases when offline computing technologies, such as database searching with punched cards, are reviewed if they are important to the development of online retrieval systems. ...

- 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
- 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
- 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
- Many researchers in medical and life sciences commonly use the PubMed online search engine (http://www.pubmed.gov) to access the MEDLINE bibliographic database. The researchers' strategies were investigated as a function of their knowledge of the content area. Sixteen life science researchers with no experience in neuroscience and 16 neuroscience researchers of matched professional experience performed five bibliographic search tasks about neuroscience topics. Objective measures and concomitant verbal protocols were used to assess behavior and performance. Whatever their knowledge of PubMed, neuroscientists could find adequate references within the allotted time period. Despite their lack of knowledge in neuroscience, life scientists could select adequate references with the same efficiency. However, differences were observed in the way neuroscientists and life scientists proceeded. For instance, life scientists took more time to read the task instructions and opened more abstracts while selecting their answers. These data suggest that regular use of online databases combined with graduate-level expertise in a broad scientific field like biology can compensate for the absence of knowledge in the specific domain in which references are sought. The large inter-individual variability in performance within both groups implies that beyond domain knowledge, individual cognitive abilities are the main determinants of bibliographic search performance.

- Abstract
- CD-ROMs generate increased questions that require individual instruction, staff training and bibliographic instruction. Many libraries are moving away from CD-ROMs towards locally mounted databases and access to remote databases, but the variety and sheer number of CD-ROMs may guarantee their survival, especially in larger university libraries or special libraries. With increasing services and collections offered, quality reference service may decay. Discusses undergraduates and the learning process and improvements to service instruction and the reference service
