Template:Doi
This template is intended to allow simple standardized links to digital object identifiers (DOIs). It is now redundant in most cases, because Wikibooks will automatically parse [[doi:10.1016/j.coi.2004.08.001]] as the link doi:10.1016/j.coi.2004.08.001.
If you do wish to use this template, the basic usage is:
{{doi|10.1016/j.coi.2004.08.001}}
which produces:
The template supports all symbols found in DOIs, including [];<>.
