NOTES: Interregionally coauthored articles have at least one collaborating institution from indicated region/country and an institution from outside that region/country. Article counts from set of journals covered by Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Articles classified by year they entered database, rather than year of publication, and assigned to region/country on basis of institutional address(es) listed on article. Articles on whole-count basis, i.e., each collaborating region/country credited one count. See appendix table 5-23 for countries/economies included in each region. Detail adds to more than 100% because articles may have authors from more than two countries/economies. Asia computed as sum of collaboration among China, Japan, Asia-8, and Other Asia.
