Proportion of references per Subject Category
Note: Publications and Cites were assigned to ISI Subject Categories (SC, subdisciplines) using directly the field provided in the records of the Web of Science (WoS). Hence 100% of Publications and Cites can be assigned to SCs.
However, WoS does not provide the SC of references. The assignation of references to SCs was made using the list of journals in the ISI Journal Citation Reports (JCR) in 2009. Since many references are to journals not in the JCR, books and reports, only a subset of the references of each organisation could be assigned.
