Social Science Citation Index

[Loet Leydesdorff]

Dear colleagues, 

 

It seems that the practice which we know from the Arts & Humanities Citation
Index, namely that records are fed into it from the SoSCI and SCI, is now
(since v5?) also in place for the SoSCI with records from the SCI. 

 

For example, the journal Annals of Epidemiolgy which is part of the SCI in
terms of the JCR contains 130 documents in 2011 of which 52 are also covered
by the SoSCI (because of their social-scientific relevance). Whereas the JCR
for the SoSCI 2011 lists only 2,966 journals, materials are drawn in from
another 1,811 journals in the SCI. This is 16.6% of all papers (32,042
documents out of 193,338) in the SoSCI. 

 

Note that this is different from the 254 journals which are covered by both
databases. 

 

Any suggestions? Was this elaborated somewhere from the side of Thomson
Reuters?

 

Best,

Loet
