    Abstract
    Wissenschaftliche Karrieren und Publikationen benötigen Reputation und möglichst viel Beachtung. Literatur, die diese Aufmerksamkeit findet, wird - so die gängige Annahme - häufig zitiert. Ausgehend von dieser Überlegung wurden Verfahren der Zitationsmessung entwickelt, die Auskunft über die Relevanz oder (wie im- und explizit oft auch postuliert wird) gar die Qualität einer Publikation oder eines Wissenschaftlers geben sollen.

    Abstract
    Fachzeitschriften spielen für Wissenschaftler und Praktiker bei der Verbreitung von Forschungsergebnissen und Erfahrungsberichten eine wichtige Rolle. Der vorliegende Artikel gibt eine kurze Einführung in das Feld der Informetrie, um auf dieser Grundlage eine Zeitschriftenliste auf dem Gebiet der lnformations- und Bibliothekswissenschaft (luB) einzuführen. Durch Kombination von zehn verschiedenen Zeitschriftenlisten aus Datenbanken, die relevante Literatur auf dem Gebiet der luB erfassen, wird eine umfassende Liste von 1205 relevanten Fachzeitschriften erstellt. Anhand ihrer Erscheinungshäufigkeit wird die Bedeutung einzelner Zeitschriften für das Gebiet der luB eingeordnet, wobei vier verschiedene Kategorien von Zeitschriften unterschieden werden: fünfzehn Kernzeitschriften, 88 zentrale Zeitschriften, 173 selektive Zeitschriften und 672 Randzeitschriften. Betrachtet werden darüber hinaus auch Publikationssprache und geografische Verteilung der Zeitschriften sowie die Überschneidung von verschiedenen Datenbanken untereinander.

    Abstract
    In einer szientometrischen bzw. informetrischen Studie werden internationale wie deutschsprachige Zeitschriften der Informations-/Bibliothekswissenschaft und -praxis mittels Zitationsanalyse und Expertenbefragung analysiert. Die zitatenanalytischen Kennwerte umfassen den Impact Factor, die Halbwertszeit, die Zitierfreudigkeit, die relative Häufigkeit von Zeitschriftenselbstreferenzen sowie Soziogramme der einflussreichen Periodika. Der Fragebogen erhebt die Lesehäufigkeit, die Einsetzbarkeit der gelesenen Journale im Tätigkeitsbereich, die Publikationstätigkeit und die Publikationspräferenz sowohl für alle Respondenten als auch für abgrenzbare Gruppen (Praktiker vs. Wissenschaftler, Bibliothekare vs. Dokumentare vs. Informationswissenschaftler, öffentlicher Dienst vs. Informationswirtschaft vs. andere Wirtschaftsunternehmen).

    Abstract
    Dimensionen der Zeitschriftenszientometrie sind (1.) die Produktion der Zeitschrift (Artikel, Autoren), (2.) der Inhalt (Themen) (3.) die Rezeption (Leser), (4.) die formale Fachkommunikation (Referenzen, Zitationen) sowie (5.) die Redaktion (Redaktionspolitik, Verlag). Die Zeitschrift "BuB - Forum für Bibliothek und Information" (BuB) wird einer szientometrischen Analyse unterzogen. BuB ist die auflagenstärkste deutschsprachige Zeitschrift des Bibliotheks- und Informationswesens. Innerhalb des Beobachtungszeitraums von 1990 bis 2003 sind 4.297 Beiträge mit insgesamt 6.803 Referenzen intellektuell ausgewertet worden. Im Vergleich zu erwarteten informetrischen Regelmäßigkeiten zeigt BuB bemerkenswerte Besonderheiten: Nicht ein Top-Autor, sondern eine über Jahre hinweg recht homogene Gruppe von Verfassern dominiert die Literaturproduktion bei BuB. Bei den Referenzen zeigt sich eine sehr hohe Konzentration auf die eigene Zeitschrift. BuB gleicht einer Insel, an die nur wenige fremde Informationen angespült werden. Obwohl Männer und Frauen jeweils 50 Prozent der Beiträge erarbeiten, so gibt es doch sowohl Männerdomänen (vor allem Rezensionen, aber auch Aufsätze) als auch Frauendomänen (Kurzbeiträge und Tagungsberichte). Die Halbwertszeit der Referenzen ist mit 2,7 Jahre sehr niedrig, Halbwertszeiten zitierter Monographien sind dabei höher als die der zitierten Zeitschriftenartikel.

    Abstract
    Deutschsprachige Fachzeitschriften des Bibliotheks- und Informationswesens (BID) werden über Kennwerte zur Leserwahrnehmung (Lesehäufigkeit, Anwendbarkeit der gelesenen Inhalte, Publikationshäufigkeit, Publikationspräferenz), Zitatenanalyse (Impact Factor, Halbwertszeit der Referenzen, Referenzen pro Artikel, Anteil der Zeitschriftenselbstreferenzen) und der Redaktion (Struktur der Autoren- und Leserschaft, Artikelauswahl, Ablehnungsquote, Überarbeitungsquote) szientometrisch beschrieben. Besonderes Augenmerk wird auf die Gegenüberstellung der Ergebnisse der Teilstudien gelegt. Die deutschsprachigen BID-Zeitschriften werden von Praktikern als Autoren wie als Leser dominiert. Praktiker schreiben für Praktiker, es wird wenig zitiert, aktuelle Themen überwiegen. Die Ablehnungsquoten eingereichter Artikel sind gering; durchgehendes Peer Review ist bei der Artikelauswahl die Ausnahme. Einige deutschsprachige BID-Zeitschriften (vor allem die Verbandszeitschriften) gleichen informationellen Inseln. Eine informations- und bibliothekswissenschaftliche Zeitschrift, die internationalen Qualitätsstandards folgt und die für das gesamte BID relevante Themen behandelt, fehlt in den deutschsprachigen Ländern völlig.

    Abstract
    This paper has a dual character dictated by its twofold purpose. First, it is a speculative historiographic essay containing an attempt to fix the present posotion of library and information science within the context of the probabilisitc revolution that has been encompassing all of science. Second, it comprises a guide to practitioners engaged in statistical research in library and information science

    Abstract
    Data were gathered on acknowledgements in five leading information science journals for the years 1991-1999. The results were compared with data from two earlier studies of the same journals. Analysis of the aggregate data (1971-1999) confirms the general impression that acknowledgement has become an institutionalised element of the scholarly communication process, reflecting the growing cognitive and structural complexity of contemporary research.

    Abstract
    Collaboration is a major research policy objective, but does it deliver higher quality research? This study uses citation analysis to examine the Web of Science (WoS) Information Science & Library Science subject category (IS&LS) to ascertain whether, in general, more highly cited articles are more highly collaborative than other articles. It consists of two investigations. The first investigation is a longitudinal comparison of the degree and proportion of collaboration in five strata of citation; it found that collaboration in the highest four citation strata (all in the most highly cited 22%) increased in unison over time, whereas collaboration in the lowest citation strata (un-cited articles) remained low and stable. Given that over 40% of the articles were un-cited, it seems important to take into account the differences found between un-cited articles and relatively highly cited articles when investigating collaboration in IS&LS. The second investigation compares collaboration for 35 influential information scientists; it found that their more highly cited articles on average were not more highly collaborative than their less highly cited articles. In summary, although collaborative research is conducive to high citation in general, collaboration has apparently not tended to be essential to the success of current and former elite information scientists.

    Abstract
    A bibliometric analysis of 1,456 articles appearing in Indian Library and Information Science journals between 1975 and 1985 revealed that the average rate of citations per article in the field was quite low. Books and journals were identified as the major categories of documents referred to in these articles and both were positively related. It is concluded that the increase in journal citations and rate of citations between 1975 and 1985 indicates that Indian Library and Information Science journals are now publishing a higher number of research-oriented articles in comparison with earlier years.

    Abstract
    Internet based electronic resources are growing dramatically but there have been no empirical studies evaluating the impact of e-sources, as a whole, on formal scholarly communication. reports results of an investigation into how much e-sources have been used in formal scholarly communication, using a case study in the area of Library and Information Science (LIS) during the period 1994 to 1996. 4 citation based indicators were used in the study of the impact measurement. Concludes that, compared with the impact of print sources, the impact of e-sources on formal scholarly communication in LIS is small, as measured by e-sources cited, and does not increase significantly by year even though there is observable growth of these impact across the years. It is found that periodical format is related to the rate of citing e-sources, articles are more likely to cite e-sources than are print priodical articles. However, once authors cite electronic resource, there is no significant difference in the number of references per article by periodical format or by year. Suggests that, at this stage, citing e-sources may depend on authors rather than the periodical format in which authors choose to publish

    Abstract
    The paper reports a longitudinal analysis of the topical and methodological development of Library and Information Science (LIS). Its focus is on the effects of researchers' disciplines on these developments. The study extends an earlier cross-sectional study (Vakkari et al., Journal of the Association for Information Science and Technology, 2022a, 73, 1706-1722) by a coordinated dataset representing a content analysis of articles published in 31 scholarly LIS journals in 1995, 2005, and 2015. It is novel in its coverage of authors' disciplines, topical and methodological aspects in a coordinated dataset spanning two decades thus allowing trend analysis. The findings include a shrinking trend in the share of LIS from 67 to 36% while Computer Science, and Business and Economics increase their share from 9 and 6% to 21 and 16%, respectively. The earlier cross-sectional study (Vakkari et al., Journal of the Association for Information Science and Technology, 2022a, 73, 1706-1722) for the year 2015 identified three topical clusters of LIS research, focusing on topical subfields, methodologies, and contributing disciplines. Correspondence analysis confirms their existence already in 1995 and traces their development through the decades. The contributing disciplines infuse their concepts, research questions, and approaches to LIS and may also subsume vital parts of LIS in their own structures of knowledge production.

    Abstract
    Using 17 fully open-access journals published uninterruptedly during 2000 to 2004 in the field of library and information science, the present study investigates the impact of these open-access journals in terms of quantity of articles published, subject distribution of the articles, synchronous and diachronous impact factor, immediacy index, and journals' and authors' self-citation. The results indicate that during this 5-year publication period, there are as many as 1,636 articles published by these journals. At the same time, the articles have received a total of 8,591 Web citations during a 7-year citation period. Eight of 17 journals have received more than 100 citations. First Monday received the highest number of citations; however, the average number of citations per article was the highest in D-Lib Magazine. The value of the synchronous impact factor varies from 0.6989 to 1.0014 during 2002 to 2005, and the diachronous impact factor varies from 1.472 to 2.487 during 2000 to 2004. The range of the immediacy index varies between 0.0714 and 1.395. D-Lib Magazine has an immediacy index value above 0.5 in all the years whereas the immediacy index value varies from year to year for the other journals. When the citations of sample articles were analyzed according to source, it was found that 40.32% of the citations came from full-text articles, followed by 33.35% from journal articles. The percentage of journals' self-citation was only 6.04%.

    Abstract
    Purpose - The purpose of this research is to report on research undertaken into the use made of library and information science (LIS) journals in dissertations written by students undertaking the Master's course in Information and Library Studies at the University of Wales Aberystwyth. Design/methodology/approach - Analysis of the citations of 100 (post 2000) dissertations submitted gives an indication of the range of material used in dissertations. In addition, responses to questionnaires from students provide information about how relevant papers are found from LIS journals. Findings - Journals with a practical bias were cited more than research-oriented journals. Lists of the most "popular" journal titles are included. Originality/value - The research provides a "snapshot" of the use made of LIS journals by Master's students in their dissertations.

    Abstract
    The main fields of research in Library Science and Documentation are identified by quantifying the frequency of appearance and the analysis of co-occurrence of the descriptors assigned to 11,273 indexed works in the Library and Information Science Abstracts (LISA) database for the 2004-2005 period. The analysis made has enabled three major core research areas to be identified: World Wide Web, Libraries and Education. There are a further 12 areas of research with specific development, one connected with the library sphere and another 11 connected with the World Wide Web and Internet: Networks, Computer Security, Information technologies, Electronic Resources, Electronic Publications, Bibliometrics, Electronic Commerce, Computer applications, Medicine, Searches and Online Information retrieval.

    Abstract
    Describes how a representative sample of librarians was surveyed to carry out a comparative evaluation of selected journals in library and information science. Respondents were asked to rate each journal on a scale from poor to outstanding (0-10), in terms of their visibility and the quality of articles they publish. Such evaluation should assist librarians in journal selection and in determining the quality of journals to which they send their research papers for publication. Reports the findings of the survey which discovered that some journals such as Library Waves, Assistant Librarian and Library Journal get low ratings because of low visibility and irregular publication. Others such as African Journal of Library Archives and Information Science and Journal of Information Science are rated highly because of familiarity and accessibility. Argues that the results of the study should help librarians determine the quality of journals and will subsequently enhance their utilization and subscription.

    Abstract
    In an earlier study by the authors, full-text analysis and traditional bibliometric methods were combined to map research papers published in the journal Scientometrics. The main objective was to develop appropriate techniques of full-text analysis and to improve the efficiency of the individual methods in the mapping of science. The number of papers was, however, rather limited. In the present study, we extend the quantitative linguistic part of the previous studies to a set of five journals representing the field of Library and Information Science (LIS). Almost 1000 articles and notes published in the period 2002-2004 have been selected for this exercise. The optimum solution for clustering LIS is found for six clusters. The combination of different mapping techniques, applied to the full text of scientific publications, results in a characteristic tripod pattern. Besides two clusters in bibliometrics, one cluster in information retrieval and one containing general issues, webometrics and patent studies are identified as small but emerging clusters within LIS. The study is concluded with the analysis of cluster representations by the selected journals.

    Abstract
    This study utilized bibliometric tools to analyze the relationship between two separate, but related, fields: Library and Information Science (LIS) and Management Information Systems (MIS). The top-ranked 48 journals in each field were used as the unit of analysis. Using these journals, field cocitation was introduced as a method for evaluating the relationships between the two fields. The three-phased study evaluated (a) the knowledge imported/exported between LIS and MIS, (b) the body of knowledge influenced by both fields, and (c) the overlap in fields as demonstrated by multidimensional scaling. Data collection and analysis were performed using DIALOG and SPSS programs. The primary findings from this study indicate that (a) the MIS impact on LIS is greater than the reverse, (b) there is a growing trend for shared impact between the two disciplines, and (c) the area of overlap between the two fields is predominately those journals focusing on technology systems and digital information. Additionally, this study validated field cocitation as a method by which to evaluate relationships between fields.

    Abstract
    Normalization of citation scores using reference sets based on Web of Science subject categories (WCs) has become an established ("best") practice in evaluative bibliometrics. For example, the Times Higher Education World University Rankings are, among other things, based on this operationalization. However, WCs were developed decades ago for the purpose of information retrieval and evolved incrementally with the database; the classification is machine-based and partially manually corrected. Using the WC "information science & library science" and the WCs attributed to journals in the field of "science and technology studies," we show that WCs do not provide sufficient analytical clarity to carry bibliometric normalization in evaluation practices because of "indexer effects." Can the compliance with "best practices" be replaced with an ambition to develop "best possible practices"? New research questions can then be envisaged.
