Welcome to the ReACH dialogue blog! Launched at UNESCO in May 2017, ReACH is a global initiative that explores how to re-think our approach to reproducing, storing and sharing works of art and cultural heritage in the digital age. In this blog, we will go the behind-the-scenes of the global consultation which led us to the production of the new ReACH Declaration. We will present reflections, case studies and other initiatives that illustrate how the fourth industrial revolution is offering our sector unprecedented opportunities to better fulfil our mission to study, share and preserve our cultural heritage. We invite you to join this global discussion on #ReACHDialogue.
