Katharine Knox & Tony Kushner 
Refugees in an Age of Genocide [PDF ebook] 
Global, National and Local Perspectives during the Twentieth Century

This is a study of the history of global refugee movements over the 20th century, ranging from east European Jews fleeing Tsarist oppression at the turn of the century to asylum seekers from the former Zaire and Yugoslavia. Recognizing that the problem of refugees is a universal one, the authors emphasize the human element which should be at the forefront of both the study of refugees and responses to them.
