The American Psychological Association (APA) publishes its Publication Manual, now in its sixth edition, documenting (among other things) the APA Style, a citation and referencing style. APA Style is pretty common. It is pretty much the only style used in psychology journals, but is also used in other fields. There are BibTeX packages on CRAN to implement it.
We have quite a few questions related to APA style.
I propose creating a new tag apa-style and retagging these questions (except for this one and this one) unless there are objections.
Thoughts?
