Scopus is an abstract and citation database. It is particularly useful for exploring connections between articles, following reference and citation trails to find the way to related information.

There is a useful suite of tutorials on how to use Scopus: https://service.elsevier.com/app/answers/detail/a_id/14799/#doc

As well as standard searches, they explain how to see which more recent documents cite a publication, numbers of citations, and other useful metrics and information about a publication and its author. Such information can help with the evaluation of a position of an article or other publication within its field.

It is always worth checking for useful comparable functionality in other search systems and databases. For example, even the ‘cited by’ button in Google Scholar is a simple means of citation tracking.
