IntroductionSee also Grey literature and Hand-searching Snowballing is a term used in expert searching and refers to locating or tracking down references from the bibliographies of existing scientific articles in a continuous process of evaluation, inclusion and synthesis. It also obliquely refers to searching for the grey literature and is used in conjunction with hand-searching and systematic review searching. Where previous research is available (preliminary findings, journal articles from database searches, known authors or websites etc.) use existing materials to locate other relevant articles and to determine the key researchers in a field or subject domain. Digital "snowballing"Digital snowballing is a way to extend the search for articles to include items in Google scholar, Web of Science and via "related articles" in PubMed. These are just some of the techniques used by health librarians to begin to find items that might be missed by conventional online retrieval methods. Snowballing is sometimes referred to as reference harvesting. Think of rolling a snowball as a metaphor for information retrieval and picking everything up in your path. See also
