CrossMark Policy

CrossMark is a multi-publisher initiative from Crossref to provide a standard way for readers to locate the current version of a piece of content. By applying the CrossMark logo Publisher Name is committing to maintaining the content it publishes and to alerting readers to changes if and when they occur.

Clicking on the CrossMark logo will tell you the current status of a document and may also give you additional publication record information about the document. Articles in Press will not have the CrossMark icon for the present. Content that will have the CrossMark logo is restricted to current (since 2016-Nov) and future journal content.

Errata
Errata concern the amendment of mistakes discovered after publication has been made. Errata are generally not published for simple, obvious typing errors, but are published when an apparent error is significant. After an erratum has been published the original paper will be corrected and a link to the erratum is shown.
