Twenty years ago the Berlin Wall fell, and this dramatic transformation has continued to fascinate historians and political scientists. The National Security Archive at George Washington University recently released this electronic briefing book which offers some fascinating documents related to this subject. Some of these documents include transcripts of conversations between President George H.W. Bush and West German Chancellor Helmut Kohl and excerpts on Germany from the Malta summit between Bush and Soviet leader Mikhail Gorbachev. Visitors to the site can read these documents in their entirety, and they may also want to sign up for the National Security Archive's email list. Also, visitors can learn about the forthcoming book, "Masterpieces of History: The Peaceful End of the Cold War in Europe, 1989".
