Snowballing and cited reference searching

Snowballing and cited reference searching build on an article or other document you already know is relevant to your study – a “citation pearl”.

  • Look through the list of cited references to go back in time by following up the sources the authors used. This is often called snowballing. 

  • Use the “citation pearl” to go forward in time by using a citation index. The quickest way is to paste the title into Google Scholar and click 'Cited by'.
