Biological Psychiatry, as its name suggests, has a much less ambitious program, because it addresses genetic, anatomical, biochemical, and pharmacological aspects of mental disorders and almost nothing else. Within its announced domain, its authors—there are many of them, nearly all from the United Kingdom—have succeeded admirably. The contributors write well, and they document their assertions with data and abundant references. They provide valuable information on the genetics of mental illness, imaging techniques, and psychopharmacology. I recommend the work highly as an accurate guide to the latest knowledge in "biological psychiatry" up to, say, 1995.
