DOI Agency
A DOI agency is an organization responsible for assigning Digital Object Identifiers (DOIs) to scholarly content, ensuring its long-term accessibility and citation. Major DOI agencies include CrossRef, which primarily serves journals, books, and academic publications, and DataCite, focused on assigning DOIs to datasets and research data. mEDRA is a European agency that caters to publishers of books, journals, and multimedia content. Zenodo is an open-access platform that provides free DOI registration for various research materials. These agencies are essential for maintaining permanent, stable links to academic work, enhancing visibility, citation, and accessibility in the research community.
