This book is the definitive, official companion volume to the National September 11 Memorial Museum. It provides visitors with a lasting record of their experience at the museum, and tells the story of September 11 through essays on and photographs of the installations and thoughtfully curated artifacts that serve as touchstones to the day and its aftermath. It also provides a behind-the-scenes glimpse-through photographs and planning concepts-into the evolution of the museum from idea to finished entity. By maximizing the visual impact through the innovative use of photography and design, the book immerses the reader in the visceral emotion of both the museum and the day-September 11-itself. No Day Shall Erase You offers an authoritative narrative of 9/11, as it is presented in the National September 11 Memorial and Museum, and as told by Alice M. Greenwald, the museum's director, and other key staff who planned and built the museum. Focusing on the historic impact of the event, No Day Shall Erase You recognizes the central importance 9/11 has in America's national memory, as well as putting the day into context fifteen years later.
