Footnotes and bibliographies take the researcher back to additional, previous sources. Cited reference searches are the opposite, carrying the search forward to new sources that have cited a known work.
Change Basic Search to Cited Reference Search. Enter the information for your known work to see which works have cited it later. Search options include cited author, cited work, and cited year.
In full text databases such as American Chemical Society Journals, when you search Anywhere your search will include the footnotes.
