Scopus
Scopus is an interdisciplinary citation and abstract database covering 36,377 titles (22,794 active titles and 13,583 inactive titles) from approximately 11,678 publishers, of which 34,346 are peer-reviewed journals. In addition, Scopus tracks cited and citing literature.
Scopus can be used to identify highly cited authors and institutions, authors writing in specific journals in a field, and much more. It can also be used as a quality filter in research for finding "highly cited" papers that match your keywords, using the feature of sorting results by the number of times cited in other scientific papers.
