Citation chaining is a strategy researchers use to leverage the web of citations around a relevant information source (article, book, etc.). Use backwards chaining to mine the References/Bibliography/Works Cited for additional useful resources. Use forward chaining to locate resources that have cited the resource.
The University of Oregon has an excellent guide on how to do both backwards and forwards chaining: https://researchguides.uoregon.edu/litreview/citation-chaining. Remember to substitute the EWU Library catalog, databases, etc., rather than the UO resource links.
