Cited references are a feature on many databases. 
For example, EBSCO databases, ScienceDirect and
MathSciNet all include cited references.
 

A citation alert notifies you by email when a selected article is cited by another article. Citation Alerts can be set up in Scopus, ScienceDirect and Google Scholar.

Cited reference searching enables you to find articles that have cited a particular author, article or book. Cited reference searching is useful to:

• find out how research has been applied or developed.
• identify important articles in a field.
• locate current research based on earlier research.
• track your own research.

Use one of the following databases:

Scopus
Scopus is a multidisciplinary database covering sciences and social sciences.

• Follow the cited by links in the search results. Results can be sorted by the number of times cited.
• Use the citation tracker feature to find out the number of times an article or author has been cited over a period of time.
• Select an author search to search for papers by a particular author
  ​

Google Scholar 
Google Scholar search results have a "cited by" link in the search results that can be used to find articles which have referenced a particular paper. It is also possible to search through the cited references using relevant keywords.
