Never Forget - 9/11 20th Anniversary Poster

This September marks twenty years since the 9/11 terrorist attacks that occurred on U.S. soil and took the lives of nearly 3,000 people. Many who lived through that day remember where they were when they heard about the hijacked planes or watched the burning and collapse of the Twin Towers broadcast by national and local TV news stations across the nation.

The Porter Henderson Library has created this guide to commemorate the 20th anniversary of the 9/11 attacks, to honor the memory of the people who lost their lives as a result of those attacks, and to provide the Angelo State University community a starting point for acquiring a deeper understanding of 9/11, its origins, and its ongoing implications.
