@emjric As others have mentioned, Neurotribes is really good for a deep, thoroughly researched look into the history behind our awareness and knowledge of autism. There is more recently revealed historical information about Hans Asperger's relationship with the Nazis.
I highly recommend Luke Beardon's book, Autism and Asperger Syndrome in Adults.
I especially like his term, the predominant neurotype (PNT) to describe neurotypical people.
@emjric In addition to Ask An Autistic!, on Youtube I would recommend these.
For mental health in general, I love Kati Morton
