- Abstract
- Large scale uncitedness refers to the significant proportion of articles that do not receive a single citation within 5 years of publication. Notes the brief and troubled history of this area of inquiry, which was prone to miscalculation, misinterpretation, and politicization. Reassesses large scale uncitedness as both a general phenomenon in the scholarly communication system (with data for the physical sciences, social sciences and humanities) and a case study of library and information science, where its rate was reported to be 72%. The study was in 4 parts: examination of the problem of disaggregation in the study of uncitedness; review of the reaction of the popular press and scholars to uncitedness; a case study of uncitedness in C&RL; and a brief summary with suggestions for further research. Data disaggregation was found to be essential in interpreting citation data from tools such as Science Citation Index, Arts and Humanities Citation Index and Social Sciences Citation Index; which do not differentiate between articles and marginal materials (book reviews, letters, obituaries). Stresses the dangers of conclusions from uncitedness data

- Abstract
- The delimination of a research field in bibliometric studies presents the problem of the diversity of subject classifications used in the sources of input and output data. Classification of documents according the thematic codes or keywords is the most accurate method, mainly used is specialized bibliographic or patent databases. Classification of journals in disciplines presents lower specifity, and some shortcomings as the change over time of both journals and disciplines and the increasing interdisciplinarity of research. Standardization of subject classifications emerges as an important point in bibliometric studies in order to allow international comparisons, although flexibility is needed to meet the needs of local studies

- Abstract
- Scientific information has stopped growing exponentially as in the last 300 years. Nevertheless, the number of scientific papers published yearly remains dramatic. Well orderd databases and sophisticated search systems allow scientists to find the needle in the haystack. A growing number of factual databases as well as more reviews compress and refine information. Not searching but controlling and working up information appear to become the most important problem in the future

- Abstract
- Addresses the problem of evaluation of research work both by objective characterization, accessible to proof, and by adequate characterization, referring to the content and cognitive level of the work under investigation. A short discussion of established methods by science indicators as well as by peer review compiles merits and shortcomings of these methods. A short review refers to a few approaches towards the development of criteria for an improved assessment and characterization of research work and their shortcomings are discussed. Notably for the evaluation of medium or low range quality no reliable method is available. Therefore a systematic compilation of criteria which covers the full range of excellence to failure with respect to scientific quality is developed and a comprehensive list of criteris is presented which should provide a basis for objective and adequate characterization of publications

- Abstract
- In a series of articles, Don Swanson explores the problem of associating two or more literatures that are logically, or substantively, related, but bibliographically noninteractive. He has called these implicit links among published literatures undicovered public knowledge. This article explores the fate of Swanson's ideas, using citation content analysis both to determine which authors have utilized Swanson's ideas and to examine the uses to which they have been put. The results suggest that while Swanson has received significant attention from the library and information science community, his ideas have not been widely cited in biomedical disciplines, and, when cited, only with rhetorically dismissive qualifications that detracts from their facticity. These results are interpreted as a failed instance of interdisciplinarity communication, and several explanations of this failure are discussed

- Abstract
- Much effort has been done to develop more objective quantitative methods to analyze and integrate survey information for understanding research trends and research structures. Co-word analysis is one class of techniques that exploits the use of co-occurences of items in written information. However, there are some bottlenecks in using statistical methods to produce mappings of reduced information in a comfortable manner. On one hand, often used statistical software for PCs has restrictions for the amount for calculable data; on the other hand, the results of the mufltidimensional scaling routines are not quite satisfying. Therefore, this article introduces a new iteration model for the calculation of co-word maps that eases the problem. The iteration model is for positioning the words in the two-dimensional plane due to their connections to each other, and its consists of a quick and stabile algorithm that has been implemented with software for personal computers. A graphic module represents the data in well-known 'technology maps'
