I was wondering why biblatex-apa
was not suppressing the urldate
from being printed. So I looked around and I found the question Odd date output from biblatex-apa, but found out that it was more about the format of the date.
The American Psychological Association style manual states that
"Do not include retrieval dates unless the source material may change over time (e.g., Wikis)" (American Psychological Association, 2010, p. 192)
Question: How do I suppress the retrieval date from being printed (unless perhaps I am citing a wiki)?

Myers, S. W., Ballweg, M., \& Wedberg, J. L. (n.d.).

I know that I can manually delete urldate
from my entry in the bib
file but I would rather not do that as I use the same file when working with other citation styles.
