Title
¬The generation of aggregated journal-journal citation maps on the basis of the CD-ROM version of the Science Citation Index
Source
Scientometrics. 31(1994) no.1, S.59-84
Year
1994
Abstract
Describes a method for the generation of journal-journal citation maps on the basis of the CD-ROM version of the Science Citation Index. Discusses sources of potential error from this data. Offers strategies to counteract such errors. Analyzes a number of scientometric periodical mappings in relation to mappings from previous studies which have used tape data and/or data from ISI's Journal Citation Reports. Compares the quality of these mappings with the quality of those for previous years in order to demonstrate the use of such mappings as indicators for dynamic developments in the sciences
