What is Crossmark?

Crossmark is an initiative to provide a standard way for readers to locate the current version of a piece of content. By applying the Crossmark button, Annals of Psychophysiology (APP) is committing to maintaining the content it publishes and to alert readers to changes if and when they occur.

Clicking on the Crossmark button will tell you the current status of a document and may also give you additional publication record information about the document.
