Researching for your literature review: Supplementary searching

Further search techniques

Supplementary search techniques may be used as part of your scoping searches, to locate a gold set of relevant articles for testing your search, or, in order to develop a search strategy on a niche topic.

A common techniques is to start with one or more relevant articles and use these as a starting point. This is often called citation searching or snowballing.

Citation searching is a search method that can be done forward or backward in time.

  • Forward citation searching retrieves records that have cited an item, also known as “cited by”. This provides you with more recently published articles that may be relevant for your topic. 
  • Backward citation searching involves records that an item has cited (these will be located in the article's reference list). This is also known as snowballing - using known relevant articles to identify other key articles or search terms.

The main citation databases are Scopus, Web of Science and Google Scholar.
