Knowing definitively who collects or identifies a vouchered museum specimen offers new benefits for both individuals and groups. Usually, digitized data for collection objects (e.g. herbarium sheets) pivot around the “what” and include where and when. The who information ends up as unstandardized “text strings” making it difficult to index or search, which limits usefulness for everyone. If we know more about the who, we gain a searchable data asset offering unique insights for many groups including: collectors, researchers, collections staff, students, underrepresented groups, organizations, and the public. Unique identifiers for people provide the means to do this (e.g. Wikidata “Q numbers”, ORCiD “IDs”). Of course, not everyone associated with specimen vouchering has an identifier like this (yet). For current and historical collections, it turns out we can all work together to assign these people identifiers. Using Wikidata as a shared knowledge management tool means we can all contribute to implement effective knowledge transfer and reduce duplication of effort. Doing this work openly allows anyone who wants to, the chance to help. Then, using Bionomia software (Bionomia.net), anyone can work to link specimen records definitively to a person with a globally unique identifier. This work makes all sorts of new discoveries and impact metrics possible both for an individual and any organizations housing these materials who also steward and publish the related factual data to aggregators such as the Global Biodiversity Information Facility (GBIF). For example, scientists taking part in this work often discover uses of their specimen data in research papers they did not know about. To uncover tacit people information and its power, we need to find ways to promote identifiers, engage more people to do this work worldwide, store these IDs in our collection databases, and increase Wikidata entries for people associated with vouchered collections (Groom, et al 2022). Once these data exist, we can reveal hidden individuals and their contributions to science and compile individual and institution-level metrics. At the cross-domain level, this work and the tools used to do it, foster culture change in our worldwide biodiversity data and collections communities. Individuals gain the power to contribute expertise across domain disciplines and outside the walls of a physical collection or local collection database. Everyone gets the equally valuable gifts of discovering who (and what) makes their collections unique or where they have much in common with others they can share. It becomes easier to find the research, novel uses, outreach, education, and policy development made possible through people collecting and identifying these specimens. Organizations and administrators find a new window with which to look at the positive and long-lasting impact of their support for collections and the people who create and curate them.  In this symposium, you will discover who is doing this work, how it is being done, who benefits and how, along with outstanding community needs and opportunities for you. With these data we can better understand our past, and illuminate the future, for people, the specimens, and the data.
