JCUA started participating with Crossmark
During the publishing process, corrections, updates and errata, as well as retractions and withdrawals, are something that readers encounter. JCUA have banded together with CrossRef to create the CrossMark identification service. By clicking on the CrossMark logos in online PDF or HTML documents, readers can quickly learn the current status of a document. If the one they have opened is not the most up-to-date, the logo will help them to navigate to the most recent version available.
