This data story is a short introduction on how ORCIDs help the IISG to advocate products and services. The IISG is a Royal Academy of the Arts and Sciences (KNAW) institute that hosts collections and performs research on labour relations, specifically in relation to social and economic inequalities. The output of IISG comes in a large variety of products and services and it is often helpful to be able to pinpoint research, data and collections to persons as a first go-to when in need of help. Similarly, professionals (e.g. researchers and archivists) feel compelled (or are even obliged) to keep a record of the products and service they need to deliver. In both cases, ORCID.org provides a solution by allowing professionals to (1) create a unique id that is shareable across the World Wide Web, and (2) allow professionals to (automatically) gather data on their output.
