Few events in the past 50 years have impacted American life as greatly as the terrorist attacks of September 11, 2001. What transpired that single day played as much of a role in shaping our current domestic and foreign policy as any war. A decade later, the event remains fresh in Americans’ minds and continues to fuel numerous public debates—including ones centered around conspiracy theories.

This work offers a sweeping collection of A–Z entries and primary source documents that presents a thorough examination of all the individuals, groups, and events surrounding the 9/11 terrorist attacks.

Commemorating the 10th anniversary of the attacks on the World Trade Center and Pentagon, The 9/11 Encyclopedia: Second Edition offers valuable perspective on this emotionally charged and multidimensional subject. This comprehensive two-volume encyclopedia details the events leading up to the attacks, going back a decade prior to 9/11, and covers all the major players involved. It also examines events and discoveries since 2001 that have influenced our understanding of—and reactions to—the world-changing attacks.

In the second edition, dozens of entries have been updated and many new ones added. The documents volume has been expanded as well. With more than 170 A–Z entries, dozens of descriptive sidebars, and over 55 primary-source documents, this updated encyclopedia is an essential source for comprehending one of the darkest moments in American history.

  • A documents volume of more than 55 key primary source documents, including new ones added for the second edition
