History can be said to be the discipline that studies other disciplines. It is inherently interdisciplinary. One discipline with which history is closely allied is literature.
To search for information about the literature of an historical period, use the MLA International Bibliography (Ebsco)
You can also learn about the history of another discipline by utilizing the databases specific to that discipline. For example, you can learn about the history of Education by searching the permier database for that discipline--ERIC Database (Ebsco)
Anthropology is an allied discipline. AnthroSource is a standard database for Anthropology.
