SCI stands for Science Citation Index, a multidisciplinary citation index. The larger version Science Citation Index Expanded (SCIE) covers 9,000+ significant journals across 177 scientific disciplines, from 1900 to the present.

Likewise, SSCI stands for Social Science Citation Index, which covers 3,000+ academic journals across 57 disciplines in the social sciences.

Those journals indexed by SCI and SSCI are described as the world’s leading journals. The two indexes are available online through the Library’s Web of Science platform.
