Issues related to population ageing and longer working lives span diverse research areas and are linked to a number of conceptual and policy debates. Here we provide details of texts which allow quick access to key debates in the different domains covered by the contributions. We focus first on social policy, retirement and pensions. We then provide key sources on the changing experiences and perceptions of retirement; age-discrimination, human resource management and older workers; and early exit, mature-age unemployment and activating older workers.
