CWTS Journal Indicators

[Nees Jan van Eck]

The 2012 SNIP values have been released on CWTS Journal Indicators
(www.journalindicators.com). SNIP (source normalized impact per paper) is a
freely available journal impact indicator that uses a source normalization
mechanism to correct for differences in citation practices between fields of
science. Compared with the journal impact factor, SNIP allows for more
accurate comparisons between journals active in different scientific fields.
SNIP is calculated by CWTS based on Elsevier's Scopus database. With the
release of the 2012 SNIP values, stability intervals have been added to CWTS
Journal Indicators. These intervals indicate the reliability of the SNIP
value of a journal. For instance, if a journal's SNIP value is largely due
to a single very highly cited publication, this is indicated by a wide
stability interval. SNIP is the only freely available journal impact
indicator that is presented with stability intervals.

 

Your feedback on CWTS Journal Indicators is greatly appreciated.
