Most of the books I have read about disabled people are from the perspective of the disabled person and are somewhat autobiographical. The disabled in movies seem to often be either a tokenistic afterthought in the name of diversity, or someone who the movies goes through great pains to portray as "normal". As a result, none of these experiences have given me an overview of disabled culture, as such.
This book -- though it does contain many pieces I had read before -- provides such an overview. It has fiction, non-fiction, poetry and theater sections. The disabilities of the writers range from quadriplegia to hemophilia to cerebral palsy. Some of the pieces dwell on the disability, many do not. Very few of the writers are names you have heard of before unless you are well versed in the writing of the disabled. As a side note, many of the writers are also gay which creates an odd and interesting juxtaposition of subcultures
