Snowball research is an effective way of finding sources for your project, paper, or presentation. This research method utilizes the citation list from relevant sources you may already have.
Start with one source written by a reputable author that is very relevant to your research thesis or argument and scan the references listed. Search and find a citation(s) that is related to your topic.
Check the related article to ascertain whether it assists you in your research efforts. After evaluating the next source(s) for credibility, locate another relevant reference listed. Roll and repeat!
