Crossmark - Crossref

The Crossmark button gives readers quick and easy access to the current status of an item of content, including any corrections, retractions, or updates to that record. Crossmark provides a cross-platform way for readers to quickly discover the status of a research output along with additional metadata related to the editorial process. Crucially, the Crossmark button can also be embedded in PDFs, which means that members have a way of alerting readers to changes months or even years after it’s been downloaded.
