- Abstract
- Aging of publications, percentage of self-citations, and impact vary from journal to journal within fields of science. The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid. Furthermore, the delineation of fields and among specialties is fuzzy. Institutional units of analysis and persons may move between fields or span different specialties. The match between the citation index and institutional profiles varies among institutional units and nations. The respective matches may heavily affect the representation of the units. Non-Institute of Scientific Information (ISI) journals are increasingly cornered into transdisciplinary Mode-2 functions with the exception of specialist journals publishing in languages other than English. An externally cited impact factor can be calculated for these journals. The citation impact of non-ISI journals will be demonstrated using Science and Public Policy as the example.

- Abstract
- In one of two bibliometric papers in this issue Brown looks at formal publication and citation of Eprints as shown by the policies and practices of 37 top tier physics journals, and by citation trends in ISI's SciSearch database and Journal Citation Reports. Citation analysis was carried out if Eprint cites were indicated by editor response, instruction to authors sections, reports in the literature, or actual examination of citation lists. Total contribution to 12 archives and their citation counts in the journals were compiled. Of the 13 editors surveyed that responded, 8 published papers that had appeared in the archive. Two of these required removal from the archive at publication; two of the 13 did not publish papers that have appeared as Eprints. A review journal that solicits its contributions allowed citation of Eprints. Seven allowed citations to Eprints, but were less than enthusiastic.Nearly 36,000 citations were made to the 12 archives. Citations to the 37 journals and their impact factors remain constant over the period of 1991 to 1998. Eprint citations appear to peak about 3 years after appearance as do citations to published papers. Contribution to the archives, and their use as measured by citation, is clearly growing. Citation form and publishing policy varies from journal to journal.

- Abstract
- Aggregated journal-journal citation networks based on the Journal Citation Reports 2004 of the Science Citation Index (5,968 journals) and the Social Science Citation Index (1,712 journals) are made accessible from the perspective of any of these journals. A vector-space model Is used for normalization, and the results are brought online at http://www.leydesdorff.net/jcr04 as input files for the visualization program Pajek. The user is thus able to analyze the citation environment in terms of links and graphs. Furthermore, the local impact of a journal is defined as its share of the total citations in the specific journal's citation environments; the vertical size of the nodes is varied proportionally to this citation impact. The horizontal size of each node can be used to provide the same information after correction for within-journal (self-)citations. In the "citing" environment, the equivalents of this measure can be considered as a citation activity index which maps how the relevant journal environment is perceived by the collective of authors of a given journal. As a policy application, the mechanism of Interdisciplinary developments among the sciences is elaborated for the case of nanotechnology journals.

- Abstract
- Purpose - The purpose of this paper is to examine the way in which library and information science (LIS) issues have been handled in the formulation of recent UK Higher Education policy concerned with research quality evaluation. Design/methodology/approach - A chronological review of decision making about digital rights arrangements for the 2008 Research Assessment Exercise (RAE), and of recent announcements about the new shape of metrics-based assessment in the Research Excellence Framework, which supersedes the RAE. Against this chronological framework, the likely nature of LIS practitioner reactions to the flow of decision making is suggested. Findings - It was found that a weak grasp of LIS issues by decision makers undermines the process whereby effective research evaluation models are created. LIS professional opinion should be sampled before key decisions are made. Research limitations/implications - This paper makes no sophisticated comments on the complex research issues underlying advanced bibliometric research evaluation models. It does point out that sophisticated and expensive bibliometric consultancies arrive at many conclusions about metrics-based research assessment that are common knowledge amongst LIS practitioners. Practical implications - Practical difficulties arise when one announces a decision to move to a new and specific type of research evaluation indicator before one has worked out anything very specific about that indicator. Originality/value - In this paper, the importance of information management issues to the mainstream issues of government and public administration is underlined. The most valuable conclusion of this paper is that, because LIS issues are now at the heart of democratic decision making, LIS practitioners and professionals should be given some sort of role in advising on such matters.

- "Mikhail Simkin und Vwani Roychowdhury von der University of Califomia, Los Angeles, haben eine in der wissenschaftlichen Gemeinschaft verbreitete Unsitte erstmals quantitativ erfasst. Die Wissenschaftler analysierten die Verbreitung von Druckfehlern in den Literaturlisten wissenschaftlicher Arbeiten (www.arxiv.org/abs/cond-mat/0212043). 78 Prozent aller zitierten Aufsätze - so schätzen die Forscher - haben die zitierenden Wissenschaftler demnach nicht gelesen, sondern nur per 'cut and paste' von einer Vorlage in ihre eigene Literaturliste übernommen. Das könne man beispielsweise abschätzen aus der Analyse fehlerhafter Seitenangaben in der Literaturliste eines 1973 veröffentlichten Aufsatzes über die Struktur zweidimensionaler Kristalle: Dieser Aufsatz ist rund 4300 mal zitiert worden. In 196 Fällen enthalten die Zitate jedoch Fehler in der Jahreszahl, dem Band der Zeitschrift oder der Seitenzahl, die als Indikatoren für cut and paste genommen werden können, denn man kann, obwohl es Milliarden Möglichkeiten gibt, nur 45 verschiedene Arten von Druckfehlern unterscheiden. In erster Näherung ergibt sich eine Obergrenze für die Zahl der `echten Leser' daher aus der Zahl der unterscheidbaren Druckfehler (45) geteilt durch die Gesamtzahl der Publikationen mit Druckfehler (196), das macht etwa 22 Prozent."
