    Abstract
    Over a 35-year period, Irving H. Sher played a critical role in the development and implementation of the Science Citation Index and other ISI products. Trained as a biochemist, statistician, and linguist, Sher brought a unique combination of talents to ISI as Director of Quality Control and Director of Research and Development. His talents as a teacher and mentor evoked loyalty. He was a particularly inventive but self-taught programmer. In addition to the SCI, Social Sciences Citation Index, and Arts and Humanities Citation Index,

    Abstract
    Purpose - The purpose of this paper is to provide an overview of new citation-enhanced databases and to identify issues to be considered when they are used as a data source for performing citation analysis. Design/methodology/approach - The paper reports the limitations of Thomson Scientific's citation indexes and reviews the characteristics of the citation-enhanced databases Chemical Abstracts, Google Scholar and Scopus. Findings - The study suggests that citation-enhanced databases need to be examined carefully, with regard to both their potentialities and their limitations for citation analysis. Originality/value - The paper presents a valuable overview of new citation-enhanced databases in the context of research evaluation.

    Abstract
    A citation index is a bibliographic database that provides citation links between documents. The first modern citation index was suggested by the researcher Eugene Garfield in 1955 and created by him in 1964, and it represents an important innovation to knowledge organization and information retrieval. This article describes citation indexes in general, considering the modern citation indexes, including Web of Science, Scopus, Google Scholar, Microsoft Academic, Crossref, Dimensions and some special citation indexes and predecessors to the modern citation index like Shepard's Citations. We present comparative studies of the major ones and survey theoretical problems related to the role of citation indexes as subject access points (SAP), recognizing the implications to knowledge organization and information retrieval. Finally, studies on citation behavior are presented and the influence of citation indexes on knowledge organization, information retrieval and the scientific information ecosystem is recognized.

    "Zur Kurzmitteilung "Latest enhancements in Scopus: ... h-Index incorporated in Scopus" in den letzten Online-Mitteilungen (Online-Mitteilungen 92, S.31) ist zu korrigieren, dass der h-Index sehr wohl bereits im Web of Science enthalten ist. Allerdings findet man/frau diese Information nicht in der "cited ref search", sondern neben der Trefferliste einer Quick Search, General Search oder einer Suche über den Author Finder in der rechten Navigationsleiste unter dem Titel "Citation Report". Der "Citation Report" bietet für die in der jeweiligen Trefferliste angezeigten Arbeiten: - Die Gesamtzahl der Zitierungen aller Arbeiten in der Trefferliste - Die mittlere Zitationshäufigkeit dieser Arbeiten - Die Anzahl der Zitierungen der einzelnen Arbeiten, aufgeschlüsselt nach Publikationsjahr der zitierenden Arbeiten - Die mittlere Zitationshäufigkeit dieser Arbeiten pro Jahr - Den h-Index (ein h-Index von x sagt aus, dass x Arbeiten der Trefferliste mehr als x-mal zitiert wurden; er ist gegenüber sehr hohen Zitierungen einzelner Arbeiten unempfindlicher als die mittlere Zitationshäufigkeit)."

    Abstract
    The invention of the citation index was credited to Shepard (1873) and Shapiro described a legal citation index published in 1743. A similar index was embedded in the Talmud 2 centuries earlier (1546). The 1st Hebrew citation index to a printed book is dated 1511. The earliest Hebrew manuscript citation index, ascribed to Maimonides, dates from the 12th century. Considerable knowledge was assumed for users of these tools. The substantial knowledge of their compilers contrats with the semi-automatic production of modern citation indexes. The terms citation, quotation, reference, cross-reference, locator, and concordance are employed inconsistently in publications about Hebrew indexes. There is a lack of citation links between the secondary literature on Hebrew indexes and that of citation analysis

    Abstract
    Investigates the characteristics of Journal Citation Reports (JCR) through the study of the Science Citation Index (SCI). Other criteria for evaluating a journal are also discussed. The compilation process of SCI data, and the characteristics, applications and limitations of SCI are studied. A detailed description of JCR is provided including: journal ranking listing, citing journal listing, cited journal listing, subject category listing, source data, impact factor, immediacy index, cited half-life and citing half-life. The applications and limitations of JCR are also explored. In addition to the criteria listed in JCR, the size, circulation and influence of journals are also considered significant criteria fir evaluation purposes

    Abstract
    The Web of Science, an online database of bibliographic information produced by Thomson Reuters- draws its real value from the scholarly citation index at its core. By indexing the cited references from each paper as a separate part of the bibliographic data, a citation index creates a pathway by which a paper can be linked backward in time to the body of work that preceded it, as well as linked forward in time to its scholarly descendants. This entry provides a brief history of the development of the citation index, its core functionalities, and the way these unique data are provided to users through the Web of Science.

    Abstract
    This paper examines the probability structure of the 2005 Science Citation Index (SCI) and Social Sciences Citation Index (SSCI) Journal Citation Reports (JCR) by analyzing the Impact Factor distributions of their journals. The distribution of the SCI journals corresponded with a distribution generally modeled by the negative binomial distribution, whereas the SSCI distribution fit the Poisson distribution modeling random, rare events. Both Impact Factor distributions were positively skewed - the SCI much more so than the SSCI - indicating excess variance. One of the causes of this excess variance was that the journals highest in the Impact Factor in both JCRs tended to class in subject categories well funded by the National Institutes of Health. The main reason for the SCI Impact Factor distribution being more skewed than the SSCI one was that review journals defining disciplinary paradigms play a much more important role in the sciences than in the social sciences.

    Abstract
    In einer früheren Studie wurde bereits der 'informationelle Mehrwert' von bibliographischen Datenbanken durch bibliometrische Nutzung untersucht. Im folgenden soll nun eine visuelle Oberfläche vorgestellt werden, die mit Hilfe einer bibliometrischen 'Sekundärdatenbank' einerseits die Nutzungsmöglichkeiten der zugrundeliegenden bibliographischen Datenbanken vor allem in den Bereichen Wissenschaftsinformation, Forschungsevaluation und Wissenschaftspolitik erweitern soll, andererseits aber auch eine Rückkopplung zu den Aufgaben des traditionellen Retrievals erlaubt. Die visuelle Oberfläche 'Visual Bibliometrics' ist eine Erweiterung des CD-Edition des 'Science Citation Index' und des 'Social Science Citation Index'

    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
    Since the 'Science Citation Index' emerged within the system of scientific communication in 1964, an intense controversy about its character has been raging: in what sense can citation analysis be trusted? This debate can be characterized as the confrontation of different perspectives on science. Discusses the citation representation of science: the way the citation creates a new reality of as well as in the world of science; the main features of this reality; and some implications for science and science policy
