"The study investigated the nature of the portrayal of aged characters in children's novels which won Children's Book Council of Australia's awards in the period from 1946 to 1985. By means of content analysis, the demographic, personal and behavioural characteristics of aged characters were identified on a thirty-four item checklist. From these characteristics a portrayal score was derived to represent the extent of variation in the depiction of aged characters in the novels examined." (Kirk, 1988)
