Wikidata, a structured data repository which is freely available to anyone to edit, create, use and reuse, has emerging as a powerful tool for the library community. The ARL Wikidata Task Force White Paper (https://docs.google.com/document/d/1ZsOyw2sOD3a7xJQ6XCSYDGjZUPxGGl8tuvC7vvtlJRU/edit) lists several important use cases. This workshop, especially designed for librarians, will provide an introduction to Wikidata and opportunities for attendees to practice editing existing items and creating new items in Wikidata. In addition, attendees will be encouraged to participate in a brainstorm session to talk about the potential Wikidata projects that the UC libraries may be interested in working together.
