Once a researcher locates high-impact or key publications on his or her topic, they can take their search further by looking at the references or works cited in those articles. This is called reference searching and is also known by a few different terms: pearl growing, chain searching, and citation mining.
See the types of reference searching that can be done, their purposes, and the tools that can be used to do them.
Backward reference searching, also known as chain searching, involves identifying and examining the references or works cited in an article. It is done for the following reasons:
A second-level or second-generation backward reference search is when a researcher examines sources cited by the references used in an initial article. This allows a researcher to identify inconsistencies in the literature. Third-level or third-generation searches are where the references of articles located in a second-level or second-generation reference search are examined. These searches can also go further back.
Backward Author Searching. The works of an author can be examined by doing a backward reference search. This allows a researcher to review an author's previous work and publications, and also the development of their research.

Forward reference searching is when a researcher identifies articles that cite an original article or work after it had been published. This type of search focuses on the publications created after an an article's publication.
Forward reference searching helps a researcher do the following:
Forward Author Searching. Forward reference searching can also be done to find a particular author and his or her works. This allows a researcher to review an author's later or more current works, and also examine new developments
Tools for Forward Reference Searching. Some, but not all, journal publishers show the number of times an article has been cited and may have links to the citing articles. Check the journal where an article was published for this feature. For an example, see this article in Frontiers in Sociology medical sociology section.
