DOI Registration Agencies
DOI registration agencies include CrossRef, DataCite, mEDRA, and Zenodo. CrossRef is the largest agency, primarily assigning DOIs to journal articles, books, and conference proceedings, ensuring accurate citation and discovery. DataCite focuses on datasets and research data, promoting data sharing and citation within the academic community. mEDRA is a European agency that serves publishers of books, journals, and multimedia content. Zenodo is an open-access platform for researchers to upload digital content, like datasets and presentations, and register them with DOIs through DataCite. These agencies help maintain consistent, permanent access and citation across academic fields.
