All articles will be given a digital object identifier (DOI). DOIs are standardised digital identities used across all major scientific publishers and are managed by CrossRef. DOIs guarantee a permanent Web-address of the article, no matter where it is physically stored. So, when referring to an article you can either use the traditional reference information (name of publication, volume, issue, etc.), or use the DOI. Many people now use both notations.
