From the very beginning, the notion of practice that JAR has employed has included its own communication – or exposition, as we call it – as research. This implies that key concepts relevant to contemporary art can be engaged with even in the context of something as scholarly – and for some boring – as a journal article. In this editorial, I would like to sketch the relevance of appropriation to expose the point at which stable notions of ‘research’ are jeopardised. Such instability is perhaps difficult to evaluate but, we believe, exciting to engage with. Looking back over this and all previous issues, it becomes increasingly clear that, beyond more specific uses of ‘appropriation’, the term deserves more attention in the debates around artistic research in general.
