This is  in response to The rate of growth in scientific publications
and the decline in coverage provided by Science Citation Index by Peder
Olsesen Larsen and Markus von Inus1. While I strongly agree that
citation indexes should reflect the current trends in the scholarly
publishing community, I must disagree with their findings because they
are not based on accurate data. 

 

The Authors have derived their figures and conclusions from the SCI
(Science Citation Index), a subset of the SCIE (Science Citation Index
Expanded).  The SCI is intentionally cultivated to be a relatively small
collection of high impact journals and excellent regional journals.  The
SCIE, on the other hand,  is a comprehensive citation index covering all
science journals selected by Thomson Reuters through its Journal
Selection Process.  Additionally, the authors did not take into account
that conference proceedings are indexed primarily in the CPCI
(Conference Proceedings Citation Index), at a rate of nearly 400,000
records from approximately 12,000 conferences each year. 

 

I have provided a brief commentary that describes and quantifies the
content of the major indexes in the Web of Science. I would invite the
authors and any others who are interested to view it here

ience-Coverage-Expansion/ba-p/10663> . I welcome any feedback or further
discussion on the subject.
