Just as the library has databases covering scientific literature, there are also databases for finding political science content. 

• International Political Science Abstracts: Indexes the world's leading journals in political science.
• Proquest Social Science Search: Single search of many databases, including: EconLit; IBSS (International Bibliography of the Social Sciences); PAIS International (policy literature); Sociological Abstracts; Worldwide Political Science Abstracts.
• Articles+: Broader subject coverage than the databases above.
