N – DOI as URL

CrossRef has announced a new format for the display of digital object indentifiers (DOIs). All organisations are now encouraged to use the URL format http://dx.doi.org/doi wherever a DOI appears. This makes DOIs more user-friendly, more appropriate for mobile devices and more easily machine-readable. To address concerns that the URL string is longer than the previous format, CrossRef also recommends that publishers consider using the ShortDOI service to shorten existing DOIs.
