How to access and download academic papers supported by DOI?

Accessing academic papers via DOI is feasible using Digital Object Identifier resolution services, which provide persistent links to publisher-hosted content or open repositories. Key principles involve inputting the unique DOI string into designated resolvers such as doi.org to locate the publication; access requires valid institutional or subscription credentials for paywalled content. Necessary conditions include a correctly formatted DOI and internet connectivity, applicable across journals with DOI implementation, though limitations arise for outdated or unreleased papers. Users should verify access permissions due to copyright constraints and avoid unauthorized sharing to maintain compliance with publisher policies. To implement, first retrieve the DOI from sources like citation databases; then enter it into a resolver website to access the paper's landing page. If accessible, download via publisher options, supporting scenarios such as literature reviews or educational use, thereby enhancing research efficiency and knowledge dissemination.
