  New Web Citation Index.
  In: Online Mitteilungen. 2004, Nr.78, S.39 [=Mitteilungen VÖB 57(2004) H.1].
  
  Abstract: Philadelphia, PA USA-London UK-Princeton, NJ February, 25, 2004 - Today, Thomson ISI and NEC Laboratories America (NEC) announced their collaboration to create a comprehensive, multidisciplinary citation index for Web-based scholarly resources. The new Web Citation Index(tm) will combine a suite of technologies developed by NEC, including "autonomous citation indexing" tools from NEC's CiteSeer environment, with the capabilities underlying ISI Web of KnowledgeSM. Thomson ISI editors will carefully monitor the quality of this new resource to ensure all indexed material meets the Thomson ISI high-quality standards. During 2004, Thomson ISI and NEC will operate a pilot of the new resource to receive feedback from the scientific and scholarly community. Full access to the index is projected for early 2005. When fully operational, the new resource will be a unique content collection within ISI Web of Knowledge. It will complement the Thomson ISI Web of Science(r), and provide researchers with a new gateway to discovery 4/3 using citation relationships among Web-based documents, such as pre-prints, proceedings, and "open access" research publications.

  BIOSIS previews enhanced on ISI Web of Knowledge.
  In: Online Mitteilungen. 2002, Nr.72, S.21 [=Mitteilungen VÖB 55(2002) H.1].
  
  Abstract: Philadelphia, PA, USA January 23, 2002 - Today, ISI®, a Thomson business, announced that BIOSIS Previews®, produced by Biological Abstracts, Inc (BIOSIS) and available through ISI Web of KnowledgeSM, will include new searching and linking capabilities-enabling researchers to find the information they need to facilitate discovery. BIOSIS Previews, with coverage back to 1969, is the largest collection of biological sciences records in the world. The new search features provided by ISI Web of Knowledge enable users to search BIOSIS Previews more efficiently and comprehensively. Biosystematic code and name searching offer users the option of searching for groups of organisms by a term or combination of terms. Users will also be able to identify articles where authors have announced a new species. Concept code searching allows users to enter the five-digit code corresponding to a broad subject area in the life sciences. Users can select a specific time period for searching and limit retrieval by language and/or document type and organism. BIOSIS Previews version 2.0 enables users to link directly to cited references, times cited, and related records in ISI Web of Science*. Users can also link directly to the full text of articles. In addition, users will be able to link to ISI ProceedingsSM and ISI Current Contents Connect*.

  Whitley, K.M.: Analysis of SciFinder Scholar and Web of Science citation searches.
  In: Journal of the American Society for Information Science and technology. 53(2002) no.14, S.1210-1215.
  
  Abstract: Chemical Abstracts Service recently unveiled citation searching in Chemical Abstracts. With Chemical Abstracts and Science Citation Index both now available for citation searching, this study compares the duplication and uniqueness of citing references for works of chemistry researchers for the years 1999-2001. The two indexes cover very similar source material, so one would expect the citation results to be very similar. This analysis of SciFinder Scholar and Web of Science shows some important differences as the databases are currently offered. Authors and institutions using citation counts as measures of scientific productivity should take note.

  Abstract: Das ISI in Philadelphia bündelt seine großen Zitationsdatenbanken und bietet sie (vorzugsweise als Intranet-, aber auch als Internetlösung) als 'Web of Science'an. Im derzeitigen entwicklungsstand geht 'Web of Science' bis in die 70er Jahre zurück und weist damit knapp 20 Mill. Quellenartikel mit darin enthaltenen rund 300 Mill. Zitationen in einer einzigen datenbank nach. Neben 'gewohnten' Suchstrategien etwa nach Sachthemen oder Namen werden zitationsanalytische Suchstrategien geboten: Recherchen nach zitierter Literatur, nach zitierenden Artikeln und nach (im Sinne gemeinsamer Fußnoten) 'verwandten' Artikeln. Die Ausgabefunktionen umfassen Document Delivery via ISI sowie Links zu Artikeln, die parallel zur Druckausgabe im WWW erscheinen. Durch die Multidisziplinarität der ISI-Datenbanken sind als Kundenkreis vor allem Einrichtungen angesprochen, die mehrere Wissenschaftsfächer berühren. Hochschulbibliotheken oder Bibliotheken großer Forschungseinrichtungen dürften am 'Web of Science' kaum vorbeikommen. Parallele Produkte bei Online-Archiven, auf CD-ROM oder als Druckausgabe verlieren an Bedeutung

  Small, H.: Visualizing science by citation mapping.
  In: Journal of the American Society for Information Science. 50(1999) no.9, S.799-813.
  
  Abstract: Science mapping is discussed in the general context of information visualization. Attempts to construct maps of science using citation data are reviewed, focusing on the use of co-citation clusters. New work is reported on a dataset of about 36.000 documents using simplified methods for ordination, and nesting maps hierarchically. an overall map of the dataset shows the multidisciplinary breadth of the document sample, and submaps allow drilling down the document level. An effort to visualize these data using advanced virtual reality software is described, and the creation of document pathways through the map is seen as a realization of Bush's associative trails

  Atkins, H.: ¬The ISI® Web of Science® - links and electronic journals : how links work today in the Web of Science, and the challenges posed by electronic journals.

  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.

  Wiley, D.L.: Cited references on the Web : a review of ISI's Web of Science.
  In: Searcher. 6(1998) no.1, S.32-39,57.
  
  Abstract: Reviews the Web of Science, a new Web interface to the citation indexes produced by ISI. The Web of Science carries the past 10 years of ISI's 3 major citation indexes: AHCI, SSCI, and SCI. Combined, the 3 indexes provide access to article citations from about 8.000 journals and over 10 million records. Topics covered in the review include: pricing; searching in 2 modes: Quick Search and Full Search; lateral searching and citation matching; document delivery; full text; and documentation and help. Provides a list of selected databases that link to full text, a facility not yet available on the Web of Science

  Cawkell, T.: Checking research progress on 'image retrieval by shape matching' using the Web of Science.
  In: Aslib proceedings. 50(1998) no.2, S.27-31.
  
  Abstract: Discusses the Web of Science database recently introduced by ISI, and which is compiled from 8.000 journals covered in the SCI, SSCI and AHCI. Briefly compares the database with the Citation Indexes as provided by the BIDS service at the University of Bath. Explores the characteristics and usefulness of the WoS through a search of it for articles on the topic of image retrieval by shape matching. Suggests that the selection of articles of interest is much easier and far quicker using the WoS than other methods of conducting a search using ISI's data
