How to use DOI to find the updated version of an article?

A DOI (Digital Object Identifier) provides a persistent link to a specific version of an academic article's current location. While the DOI itself does not inherently indicate version updates, publishers leverage it as a stable reference point from which to link users to the most recent available version of the article on their platform. When accessing an article via its DOI, typically through a DOI resolver (like doi.org), you are directed to the publisher's landing page for that article. Publishers generally configure this landing page to display information about and links to the latest version they host. Therefore, checking the publisher's official page reached via the DOI is the primary method. However, publishers must actively maintain links to updates; some may provide explicit versioning information or notes like "Updated" on the page, but practices vary considerably. To locate potential updates, follow these steps: First, resolve the DOI using a resolver service (e.g., paste doi.org/your-DOI into a browser). Second, carefully examine the landing page reached on the publisher's site for any notifications of corrections, retractions, or newer versions (e.g., look for tabs like "Versions" or "Updates"). Third, if no update is apparent, search databases or institutional repositories using a known identifier like the CrossRef DOI Event Tracker, which logs versioning events associated with DOIs when publishers report them.
