When searching the Library Databases, try searching for "Bharatanatyam" as well as "Bharata natyam."
Search library databases for encyclopedia articles, book chapters, and images pertaining to your dance. Sometimes information on your dance will be found within a more general article. You can also search for information about the culture from which the dance originated. Please note that not every dance will be represented in every single database. Pro-tip: try combining the name of your dance with the word "dance" in your search.
