This working paper addresses the question, ‘How has the idea of research integrity arisen?’ and assembles an international overview of key moments, documents and organisations that have shaped the field as it operates today. This policy field is rich in actors, declarations, concordats, statements, official publications, codes, reviews and press articles. Using snowballing from bibliographies, internet searches and, occasionally the Internet Archive (‘Wayback Machine’) this document has built up an overview of the organisations that have had a role in introducing ideas associated with research integrity into different policy environments. The working paper is organised by geographical regions – global, USA, Europe, and then within Europe, the UK, Iberian and Nordic countries. Each section details the main organisations involved and summarises the documents they have produced, focusing on the ways they define or discuss ‘integrity’, and the other concepts and issues they link with that word. The account identifies key events and key moments that were formative for different strands of the term’s meaning, and some of the key actors involved. It makes regular links to the Danish research and policy environment, from which the study was conducted.
