What is a DOI?

A Digital Object Identifier, commonly known as a DOI, is a permanent digital identifier assigned to scholarly and professional content such as journal articles, books, conference papers, datasets, reports, and other research outputs. Unlike an ordinary web address, a DOI is designed to remain stable even if the content moves from one website to another.

A DOI connects a published work to its official metadata, including the title, authors, journal name, publication date, volume, issue, pages, publisher, and landing page. This makes the article easier to discover, cite, index, track, and preserve in the global scholarly communication system. DOI.org describes DOI names as persistent identifiers used by both humans and machines to identify and reliably access objects over time.

For scholarly journals, a DOI is more than a link. It is part of the article's academic identity.

Why DOI Matters for Scholarly Journals

For a journal, assigning DOIs to articles increases the credibility, accessibility, and international visibility of published content. A DOI helps researchers, libraries, indexing databases, citation tools, and academic platforms recognize a publication as a structured scholarly record.

Persistent linking When a journal website changes or platforms are redesigned, the DOI can continue directing readers to the correct landing page if metadata is properly maintained.
Better discoverability DOI metadata is used by academic search engines, indexing systems, library services, citation managers, and research databases.
Reliable citation A DOI gives authors and readers a standard way to cite and locate a publication, reducing confusion from broken URLs or inconsistent records.
Citation tracking Through Crossref services, deposited references can be matched with other registered scholarly works.
Publishing standards DOI registration is an important step toward professional publishing practice, indexing readiness, and long-term digital preservation.
