For those interested in learning more about 9/11, there are many resources. One is the Never Forget Fund. The Never Forget Fund is a campaign that supports the 9/11 Memorial & Museum’s educational programs. In addition, they preserve the museum's significance as a sacred place of remembrance, reflection and education. And as their website states, much of their focus is educating the new generation.

• “For a new generation, the hope, unity, and resilience we experienced after 9/11 are not memories lived, but history learned," the website says. "The 9/11 Memorial and Museum works to train teachers, educate students, and assist communities to understand the importance of the values we shared."
