What is the DOI?
The DOI is a unique, permanent code assigned any digital item such as a journal article. Since 1999, each article published in Royal Society journals has been assigned a unique DOI. The DOI is used by many of the major science publishers and has become an industry standard. Each DOI is assigned and maintained in a central registry managed by the International DOI Foundation. Utilising a DOI, a referenced article can be electronically located – the DOI is resolved to find the current URL of the item. For further information, please see here.
