Crossmark Policy

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.
