This paper is intended to act as a pillar and reference point for CC's advocacy work in copyright reform in the cultural heritage context, with a focus on issues arising in the digital environment. It may serve to support members of the CC community in their own advocacy efforts, guide policymakers in their legislative processes, and inform anyone interested in the policy issues gravitating around access and reuse of culture and cultural heritage. It will likely be adapted into a GLAM Guide for Policymakers and will be augmented with real-life examples, case studies and practical advice.It starts with an overview of copyright challenges to the legitimate activities of GLAMs, notably preservation (largely through digitization) and sharing of digital and digitized content images and data for access, use and reuse. It also notes copyright's chilling effects in the face of the GLAM sector's general risk aversion. The paper then offers insights towards effective copyright reform addressing those challenges, with a focus on the opportunities related to the digital environment. The proposals for reform aim to create legal certainty and international harmonization as well as to facilitate cross-border transactions.The paper encourages policymakers to recognize and support the pivotal roles of GLAMs in preserving and providing access to knowledge and culture to all members of society. It urges policymakers to engage with stakeholders to ensure there are clear, simple, and effective policies in place to support better sharing of cultural heritage in the public interest.The paper provides a high-level overview of the policy issues and, as a whole, it does not necessarily reflect the current situation in any specific jurisdiction.
