Crossref DOI display guidelines
• Crossref will be updating its DOI Display Guidelines. This is a big deal.
We last made a change in 2011 so it’s not something that happens
often or that we take lightly.
• Old format was http://dx.doi.org/
• In short, the changes are to drop “dx” from DOI links and to use
“https:” rather than “http:”. An example of the new best practice in
displaying a Crossref DOI link is: https://doi.org/10.1629/22161

19.
Crossref DOIs appear in references on the web page

20.
New DOI display guidelines
• Always make the DOI a full link – https://doi.org/
10.1006/jmbi.1995.0238 – even when it’s on the
abstract or full text page of the content that the DOI
identifies – and use “https://doi.org/”.
• http://blog.crossref.org/2016/09/new-crossref-doi-
display-guidelines.html

21.
New DOI display guidelines
• Effective March 2017
• For content going forward - you do not need to
change already published content
• http://dx.doi.org/ will continue to work and will be
supported forever
