A good place to start when researching is a subject-specific encyclopedia. Use the following two resources to search for your topic:
You may also search for general reference articles by using the OneSearch box on the library homepage but choosing the 'Find Articles' tab and the 'Reference' radio button.
Also, consider searching for a book on the general history of the country you are researching. It is likely there will be one or more chapters devoted to the genocide. There may also be books specifically about the genocide.
Genocide & Persecution series [Afghanistan, Argentina, Burma, Cambodia, Chile, Darfur, East Pakistan, El Salvador & Guatemala, Kosovo, the Kurds, Liberia, People's Republic of China, Rwanda, South Africa, Sri Lanka, Tibet, and Uganda.] and
Bearing Witness series [Titles include ISIS and the Yazidi Genocide in Iraq, Holodomor, Guatemalan Genocide of the Maya, The Nanjing Massacre, Destruction of the Inca Civilization, and Ethnic Cleansing in the Syrian Civil War.].
