Dictionary of Race and Ethnic Relations [PDF ebook] 

Ethnicity and racial relations are almost universally seen as a prime motivating force behind social conflict and change. Often volatile and complex, racial interaction resonates through all aspects of contemporary society. Social issues which appear to have little connection to race often become entagled with ethnic friction to create far more complex problems. Race is often used by individuals and political organizations to further their own objectives.
Since the 1994 publication of the third edition of this acclaimed reference book there have been enormous changes in the area of race and ethnic relations throughout the world. The Dictionary of Race and Ethnic Relations deals with these changes through in-depth articles which both define and analyze the terms. For this edition, there has been a total revision of existing entries and many new entries that take account of developments in society and intellectual trends.
Features include: * Fully updated lists of further reading and cross-references.
* New entries include: Black feminism, Causes celebres, Environmental racism, Hybridity, Postcolonialism
* Invaluable teaching and reference tool for students at all levels
