Social Sciences Citation Index This link opens in a new windowProvides access to current bibliographic information and cited references, covering more than 1700 of the world's leading social sciences journals in a broad range of disciplines. It also covers individually selected, relevant items from leading natural and physical science journals. The ISI Citation Databases collectively index more than 8,000 high quality, peer-reviewed journals cover-to-cover, providing complete bibliographic data, searchable author abstracts (science and social sciences), and cited references. Researchers can search the citation data (the footnotes of each article), taking a known, relevant paper and finding other, more recent papers that cite it.
