Persistent identifiers such as DOIs have long been used to create lasting links to research papers. But they increasingly allow you to link and disambiguate a wide range of outputs, contributors, funders and other entities on which research is built. The EU-funded FREYA project (https://freya-project.eu) is working to link together all these identifiers, enabling discovery of research, collaborators and impact. This paper will introduce the FREYA project, and its efforts to create a persistent identifier graph. We’ll draw on examples that link facility use and funding to theses in the British Library’s EThOS collection, and show how Europe PubMed Central is linking from preprints to published articles and back. These will provide best practice examples of how academics, librarians and administrators alike can apply persistent identifiers that open up and link their resources into the PID Graph, and show how they can become part of the global persistent identifier community.
