How should a DOI be referred to on a web page or in print?
The correct way to cite a DOI on a webpage is as follows: doi: 10.1000/186 The “hidden” html code would be: doi:10.1000/186 where the first part of the URL is the address of the specific DOI proxy server you wish to use. Note that http://dx.nbdrs.com is Nielsen BookData’s own proxy server; DOIs can also be resolved using proxy servers run by other organisations. Consider also that DOIs can be “hidden” on a web-page just like URLs, such that the visible link to be clicked on can be something completely different.
