 Abstract: Purpose - The purpose of this paper is to examine the five-year 
journal impact factor (JIF) score of the Journal Citation Reports VCR).
Design/methodology/approach - The paper looks at one of the important 
enhancements to the JCR, the new five-year journal impact factor (JIF) 
score. This element complements the traditional JIF scores and data. The 
new indicator addresses the criticism against the short citation window for 
evaluating the performance of nearly 8,000 scholarly and professional 
journals on a medium term.  

Findings - It may be feasible that some of the other proposals presented by 
the best scientometricians for improving the JIF and its alternatives will 
be implemented in various specialty editions of JCR. Particularly 
interesting would be the adding of scores computed through diachronous 
instead of or in addition to synchronous measurement; creating new 
indicators based on the level of uncitedness of articles in journals; and 
calculating percentile JIF, JIF point averages and/or JIFs based on article 
count, with or without self-citations. 

Originality/value - The five-year mid-term JIF complements very well the 
short-term two-year JIF for indicating the prestige, reputation and 
influence of the journals through the prism of the average productivity of 
journals and the citedness counts of articles published in the journals for 
a longer time span. As mentioned above, breaking down the various 
indicators by disciplinary and subdisciplinary categories, or even by the 
language and the country of publication of the journals (not the country 
affiliation of the authors) can provide further insight into the landscape 
of scholarly publishing.
