- Abstract
- Presents an extensive domain analysis of information science in terms of its authors. Names of those most frequently cited in 12 key journals from 1972 through 1995 were retrieved from Social SciSearch via Dialog. The top 120 were submitted to author co-citation analyzes, yielding automatic classifications relevant to histories of the field

- Abstract
- The trasition from a national science model in which the national language is used for publications and other communications, to a transnational model in which a single international language (English) is used and the market id dominated by Anglo-Saxon publishers, has continued in recent decades. The transition was still in progress for some countries and disciplines throughout the period examined here (1981-1992). The transition process was analyzed in terms of the Science Citation Index database, first by assessing direct manifestations through specific indicators, and then by checking increases in performance by considering transition as a global process. The number of publications and citations followed the expected trend, whereas changes in impact appaer to have been governed by non-transition factors

- Abstract
- Bradford's law is widely used in collection development to identify the most productive periodicals, but does nott take into account the variables of frequency of publication and number of years of publication during a particular time span. Hence not all periodicals necessarily have the same opportunity to publish relevant articles. To test this hypothesis, the productivity of American sociology periodicals during 1987-91 was analysed and shown to correlate with frequency of publication and number of years of publication, giving a more accurate representation than using Bradford's law as originally formulated

- Abstract
- Reports results of a cocitation analysis study from the international retrieval research field from 1987 to 1997. Data was taken from Social SciSearch, via Dialog, and the top 40 authors were submitted to author cocitation analysis to yield the intellectual structure of information retrieval. The resulting multidimensional scaling map revealed: identifiable author groups for information retrieval; location of these groups with respect to each other; extend of centrality and peripherality of authors within groups, proximities of authors within groups and across group boundaries; and the meaning of the axes of the map. Factor analysis was used to reveal the extent of the authors' research areas and statistical routines included: ALSCAL; clustering analysis and factor analysis

- Abstract
- There are numerous international and national programmes to encourage collaboration. However, little is known about the way in which collaboration changes the impact of a research publication. Explores hoe the impact (average citations per paper) varies with different types of collaboration. A calibrated bibliometric model is derived that demonstrates that collaborating with an author from the home institution or another domestic institution increases the average impact by about 0,75 citations while collaborating with an author from a foreign institution increases the impact by about 1.6 citations

- Abstract
- Attempts some new approaches to the presentation of bibliometric macro level indicators. Mathematics, engineering, physics and chemistry subfields are assigned to 13 science areas. Each science area then appears on 1 table (left page) and 2 graphs (right page). The 1st graph shows the main citation rates with respect to the world average on a relational chart. The countries are represented by letter codes that can be found in the corresponding table on the facing page. The 2nd graph visualizes the countries' relative research activity in the given science areas as compared to the world standard

- Abstract
- Reports results of a study, conducted at Kansas State University Library, to investigate the possibility of using DIALOG's RANK command to generate lists of prominent authors for use in cocitation studies. The emerging and rapidly expanding field of biodiversity was chosen and an online search of SCISEARCH (DIALOG File 34) was conducted to generate a list of potential authors to be used in the study. The RANK command was used to generate a ranked list of those authors cited in the retrieved documents. Results indicate that RANK does not effectively retrieve a quality set of prominent authors for use in cocitation studies. Highly cited authors of general texts of biodiversity cause the derived author map to present a misaligned picture of specialization within the field. Concludes that, by limiting citations to periodical articles only, a clearer and more accurate picture of the field should emerge

- Abstract
- Seeks to describe the social networks, or invisible colleges, that make up a scientific speciality, in terms of mathematically precise sets generated by document citations and accessible through the Social Science Citation Index. The document and author sets that encompass a scientific specialty are the basis for some interdependent citation matrices. The method of construction of these sets and matrices is illustrated through an application to the literature on invisible colleges

- Abstract
- Discusses citation counting measurements, and provides a qualitative analysis of citation analysis (also known as scientometrics or informetrics). Critically evaluates citation indexes, drawing on 2 major investigations carried out by the author. Explains the importance of the phenomenon of non-indexed citedness, and highlights some serious limitations of citation indexes as a basis for measuring the scientific literature and hence making judgements about the respective merits of individual scientists
