Applying the Crossmark icon is a commitment by Elsevier to maintain the content published and alert readers to changes if and when they occur.
What is Crossmark?
Crossmark, a multi-publisher initiative from CrossRef, provides a standard way for readers to locate the authoritative version of a document. Elsevier recognizes the importance of the integrity and completeness of the scholarly record to researchers and librarians and attaches the highest importance to maintaining trust in the authority of its electronic archive. Clicking on the Crossmark icon will inform the reader of the current status of a document and may also provide additional publication record information about the document.
The Elsevier content that will have the Crossmark icon is restricted to current and future journal content and limited to specific publication types (see below) and only on content hosted by official Elsevier websites. Articles in Press will not have the Crossmark icon for the present.
