 The Web of Science and the Science Citation Index

Explore top high-impact journals with powerful tools such as cited reference searching and Author Finder. 256 categories thoroughly cover the sciences, social sciences, arts, and humanities.

  • Science Citation Index Expanded (SCI-EXPANDED)--1900-present
  • Social Sciences Citation Index (SSCI)--1956-present
  • Arts & Humanities Citation Index (A&HCI)--1975-present


Scopus from Elsevier is a new multidisciplinary database including citation searching and therefore a competitor to  Web of Science from Thomson Reuters. Please find extensive documentation by Elsevier:

Advantage of Scopus

  • new database design providing high performance in searching and sorting of large answer sets
  •  extensive coverage of journals, technical reports, conference papers, non-English literature.
  • author identifier - Scopus tries to keep track of all name variants of an author and his afilliations
  • affiliation identifier - Scopus tries to keep track off all names of an institution and its branches
  • abstracts of older literature are included
  • online resources are covered

Drawback of Scopus

  • references starting in the year 1996, direct comparison of citation values from Web of Science to Scopus are very sensitive to correct time limits
  •  Scopus coverage of older literature depends strongly on the scientific field
