This book is intended for students, scholars, and amateur historians. It contains more than 20,000 entries covering prehistory through the year 2000. Examples of the currency of this work are the coverage on the 2000 presidential elections and the attack on the USS Cole. Coverage of Western European history has been reduced to make way for additional material on Africa, South Asia, Latin America, and the Middle East. In addition, coverage of traditional historical fields like national histories has been updated, and new historical fields such as women's history, social and cultural history, technology, and international government have been added.
