APA Style Blog addresses all things DOI
Did you know that the recently published 6th Edition of the Publication Manual of the American Psychological Association now includes the recommendations that authors include appropriate CrossRef DOIs in their references? 
Last week editors explored the implications in a series of blog posts, including a summary of the recommendation, a DOI primer, and a flow-chart of when to use DOIs.
CrossRef is interested in working with editors of other style manuals as they revisit their reference formats. We are exploring changing our own recommendations for displaying DOIs. Our preliminary thinking is that CrossRef DOIs should be displayed as clickable links to eliminate any confusion among users as to what they should do when they find one. Let us know your thoughts.
