How to obtain detailed information of an article through DOI?

A DOI (Digital Object Identifier) is a persistent, unique alphanumeric string assigned to a digital object, primarily scholarly articles, enabling reliable identification and retrieval of its detailed information. Resolving the DOI through designated systems provides access to this metadata and potentially the full text. DOI resolution fundamentally relies on the Handle System infrastructure. Key principles include mandatory registration via official agencies like CrossRef or DataCite, which maintain the core metadata linking the DOI to the resource's current location (URL) and descriptive details (title, authors, publication source, abstract). This system provides persistence, ensuring access even if the underlying URL changes. Access may be limited by publisher paywalls for the full article text, even when metadata is freely accessible. To obtain detailed information using a DOI, access a DOI resolver service. Typically, you can enter the full DOI directly into your web browser's address bar. Alternatively, use dedicated resolvers like doi.org, CrossRef's metadata search, or library-provided DOI Lookup Tools such as LibKey Nomad or Unpaywall. Many academic search engines or publisher websites also support DOI lookups. This process retrieves bibliographic metadata for citation purposes and often links directly to the article landing page for access options, saving significant researcher time.
