Abstract: Purpose - The traditional, annually issued Journal Citation Reports
(JCR) have been enhanced since the 2007 edition by the Eigenfactor Scores
(EFS), the Article Influence Scores (AIS) and the five-year Journal Impact
Factor (JIF-5). This paper aims to focus on the issues.
Design/methodology/approach - These scientometric indicators are also
available from the Eigenfactor Project web site that uses data from the yearly
updates of the JCR.
Findings - Although supposedly identical data sources are used for computing
the metrics, there are differences in the absolute scores reported, which in
turn resulted in significant (more than ten rank positions) changes for several
journals in the sample.
Originality/value - The differences in the scores and rank positions by the three
new scientometric indicators of 52 journals in the Information and Library
Science category were analysed to determine the range of differences and the
extent of changes in rank positions.
