The Discovery Of Death In Childhood And After by Sylvia Anthony
I read this as research for a short novel, but I would likely have read it anyway had I stumbled across it. A fascinating (albeit slightly old-fashioned) look at how the concept of death is acquired by young children, which then sophisticates as they get older. There are plenty of accounts of real children and their thoughts and sayings, plus a good deal of psychological and cultural work. The former is a bit limited, being mostly centred around Freud and Piaget, but it is interesting nonetheless, while the cultural sections are very interesting. All in all, this was well worth tracking down.
