Sources contain information that can be used to find other relevant sources through searching the same terms in other databases, checking the source's list of references for other cited sources, and looking at keywords in the abstract, title, or full text. Each source is also linked to newer or older sources through citation indexes that track which sources reference which other sources. These existing links and information within a source can be leveraged to discover related material.
