A digital object identifier (DOI) is a unique string of alphanumeric characters assigned to a particular item. When presented as a URL (e.g., https://doi.org/10.1098/rsos.230206), the DOI serves as a persistent link to the item and ensures that people can locate the item online over time. DOIs are registered for journal articles, book chapters, monographs, datasets, etc. and are displayed on the first page or landing page of the referenced items. When the items are cited, their DOIs are included in the citations so that people can use them to find the referenced items. In this way, DOIs serve as a key element in the scholarly communication infrastructure,
Sometimes, a DOI is presented as a string like 10.1098/rsos.230206. To convert it to a persistent link, add this part before the string: https://doi.org/, i.e., https://doi.org/10.1098/rsos.230206. More information about DOIs is available from this video:
Knowledge@UChicago is the University of Chicago's institutional repository and provides free access to the scholarly outputs from the University of Chicago community. An unpublished scholarly work (e.g., a dataset) deposited in Knowledge@UChicago will receive a DOI, which facilitates the online discoverability, citability, and long-term access of the item. If you have any questions about DOI, feel free to contact the Center for Digital Scholarship.
