Looking for reference material regarding State Hospitals, treatments done in them, and their closures up through the mid 1960s-late 1980s

Following a comment I made to something earlier, I wanted to see if I could try and get my hands on any reference material (books, preferably) about State Mental Hospitals up until they started closing in the mid-60s to late 80s.

Specifically, stuff like:
– what were the services and their overall quality?
– what was treated and how?
– was there any real uniformity? (It doesn't seem like it; for example, one northern Michigan hospital involved patients doing farming and landscaping as part of their treatment)
– what happened to the people there when they closed? did they reintegrate or struggle for the rest of their lives?
