DOI Links Now in Full Text PDF (January 1, 2005)

New volumes of Physical Review and Physical Review Letters now contain a link from the full text pdf back to the online abstract through the DOI (Digital Object Identifier). The DOI link can be found below the abstract and is blue in color. There will be a delay of a few hours between publication and activation of the link while the DOI is being registered via CrossRef.
