Aims & Scope
Change Over Time is a peer-reviewed, semiannual journal dedicated to the history, theory, and praxis of conservation and the built environment. The journal promotes multidisciplinary critical discourse between scholars and practitioners on contemporary conservation issues. Topics are examined at all scales and from diverse contexts, from the global, regional, and microscopic to the social, environmental, and material. The underlying premise, upon which the journal is founded, asserts that conservation is a complex cultural act of interpretation that has both informed and been informed by its social, cultural, and physical contexts and that to evolve, the field requires robust and challenging dialogue as to its means, methods and goals.
