- Abstract
- Purpose - The purpose of this paper is to provide an overview of new citation-enhanced databases and to identify issues to be considered when they are used as a data source for performing citation analysis. Design/methodology/approach - The paper reports the limitations of Thomson Scientific's citation indexes and reviews the characteristics of the citation-enhanced databases Chemical Abstracts, Google Scholar and Scopus. Findings - The study suggests that citation-enhanced databases need to be examined carefully, with regard to both their potentialities and their limitations for citation analysis. Originality/value - The paper presents a valuable overview of new citation-enhanced databases in the context of research evaluation.
