This talk will highlight ways that GLAM's of all sizes can utilize Wikidata to enrich their data, Provide detailed data for open images, publish Open Data and explore their collections in new ways. Glams can also use Wikidata to publish and explore their data in multiple languages. Wikidata also allows GLAM's to connect their collections together, creating a web of interconnected (linked) data. I will draw on my experience as a Wikimedian in Residence at The National Library of Wales, highlighting the challenges and successes of the project, including the appointment of the worlds first Wikidata Visiting Scholar and the way in which teams of volunteers were engaged in the project.
