It's hard to underscore the importance of the personal testimonies of Discrimination Diaries that lead to the passage of the Americans with Disabilities Act. Just hearing statistics and third person references about being disabled isn't the same thing as hearing what living with a disability is like, directly from someone who is living it.
April 1988, Justin Dart, then Chair of the Congressional Task Force on the Rights and Empowerment of People with Disabilities, began traveling the country (at his own expense) to hold public hearings to gather evidence to support the need for broad anti-discrimination protections. The documents and audio recordings became the collective Discrimination Diaries. The forums were attended by thousands of people willing to step forward and document the injustice and discrimination they faced due to their disability. 63 forums were held in total, one in every state, including the territory of Guam.
Civil Rights protections for disabled people was a key purpose of the ADA. To learn what needed to be included in the law, the disability community was asked to testify about how they are discriminated against in all areas of daily life. People were asked not only to describe physical barriers to access they encountered, but also societal prejudices and biases.
