A Digital Object Identifier (DOI) in scientific journals serves as a unique and enduring link to scholarly articles, offering stability in online access amidst changing web addresses. Functioning like a digital fingerprint, DOIs enhance citation accuracy and efficiency by providing a consistent reference point, comparable to geographical coordinates. They streamline article access by replacing cumbersome URLs with concise identifiers, significantly benefiting researchers in retrieving valuable information. Analogous to a passport for articles, DOIs ensure reliable identification and access regardless of online changes. Embracing DOIs is pivotal for their role in elevating citation reliability, enhancing efficiency, and promoting global collaboration in our digitally driven scientific landscape.
