You can find cited and citing references in most science databases. What's the difference?
Cited references ("cited in") are sources referenced by a paper. These sources are listed at the end of a peer-reviewed article. Cited references reveal background information on an article's methods or research.
Citing references ("cited by") are sources that reference a paper. In other words, the article's authors used these sources in their research. You must use a database to find citing references; unlike "Cited in" references, "Cited by" references are not listed in the article. Citing references show how an idea or topic has developed over time.
