Open Web of Science
Web of Science is a highly acknowledged citation database, indexing the most influential journals and conferences in all professional areas. Web of Science is the citation database that goes furthest back in time.
It is possible to search for subjects, authors and institutions and it is possible to search the impact of a specific article, author or institution measures by number of citations. It is in this way possible to use a citation analysis of a specific researcher to calculate a reseacher’s h-index.
