Enabling Acts: The Hidden Story of How the Americans with Disabilities Act Gave the Largest US Minority Its Rights

I had read about the demonstration on the subway stairs in Newyork prior to ADA in 'Million Years with you': A Memoir of Life Observed' by elizabeth Marshall (great author), in which her daughter contributed towards ADAPT (Americans Disabled for Accessible Public Transport). At Tovrea Castle, one of the floors was closed because it couldnt be made accessible. Thats when I realised the ADA provisions. So its history hooked me right from the cover.
As a foreign national, this book is a great way to learn how things come about in law in America. For example, the relay service adding to the phone surcharge bill, number of employees of a small business being changed to 50, so really small businesses dont go out of business trying to retrofit to ADA requirements.
I have lots of notes from the reading to refer to various acts example Decoder Circuitry Act.
The book's main premise is that its not just the activists with the demonstration that got about the ADA to happen, but the politicians and the staffers too had a great role. The book goes into great detail about people, their characteristics, background, their views towards disability, change of mind of those who were not ready for ADA, organizations that melded together for the final act.
