These databases are collections of journals covering many subjects, including history and poltical science.
Both these databases allow users to see how often an article or other item has been cited in the literature and where it has been cited.
Summon allows you to search many sources (online journals, databases, and the library catalog) to find articles, books, and more with a single search. Because it does not cover all of the library's resources, searching individual databases may be necessary for a more complete search.
Films on Demand is a searchable database of documentary films on many different topics.
