Martin Jay at Berkely has written extensively about Adorno, and would be
the place to start- his first often cited book, with a recent reintro,
is The Dialectial Imagination, and he also wrote a biography titled
Adorno, and writes about him in other books of essays- i got a hold of
them recently via amazon.com. A fascinating book  using adorno's ideas
in a critique of contemporary psychoanalysis circa 1975 is Social
Amnesia by Russell Jacoby . If he is not in psychoanalytic references
its because he was a radical social theorist who used psychoanalytic
ideas, part of the frankfurt school along with marcuse and others, and
way out of mainstream clinical psychoanalysis.
