While you've been assigned specific plays to read in this class, you might want to read others. You can look for specific plays in ANTPAC, but you can also look in several niche databases that provide full text plays.
Asian American Drama contains 252 plays by 42 playwrights.
Black Drama contains 1,462 plays by 233 playwrights.
North American Women's Drama contains 1,517 plays by 330 playwrights.
Explore new (to you) resources to locate information that will help you contextualize the plays that you are reading. These resources are listed in individual categories; however, many of them will provide information that can be helpful for multiple questions. For example, the Greenwood Encyclopedia of World Popular Culture will provide you with information about African cultures, but this will also include information about theatre, music, clothing, etc.
Where can you find information about African, African-American, and/or Asian-American theatre?
Where can you find information about African, African-American, and/or Asian-American culture and history?
After you've gained an understanding of the history/culture/FACTS surrounding your topic, it's time to see why these things have occurred and what it means in the context of your study of African drama (i.e., what are other people writing about your question). I recommend using the following three databases to locate some of this information, but there are many more (depending on your topic) that might be as, or even more, appropriate for for researching your question.
