What counting methods are used for articles and citations for a country/territory?
Country counts are based on the institutional affiliations given on published papers. A paper is attributed to a country/territory if the paper carries at least one address from that country/territory. All addresses are considered, not only the address listed first. If a country/territory appears more than once on a paper, then that paper is counted only once for that country/territory. All unique countries/territories on a paper are credited equally for the paper. All citations received by a paper are credited to all the countries/territories on the cited paper. No restrictions are made on the citing items in compiling the citation counts, other than that they are recorded from Thomson Scientific-indexed journals only.
