So I'm still working on this big essay and today I noticed that the notes we added in the .bib file are not showing up in the bibliography. It is only happening when I'm using the apa style. Maybe printing the note data field is not implemented, just like the ISBN? (Biblatex not showing ISBN with apa style) Otherwise, what am I doing wrong?
MWE:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[backend=biber,style=apa,citestyle=apa]{biblatex}
\DeclareLanguageMapping{english}{english-apa}
\addbibresource{sources.bib}
\begin{document}
Content. \parencite{something_one} More content \parencite{something-else_one} more content.
\printbibliography
\end{document}
And the sources.bib file:
@online{something_one,
author = {Some One},
title = {Something},
year = {nodate},
url = {https://somesite.org/somepage},
urldate = {2017-12-19},
note = {I'm a note}
}
@online{something-else_one,
author = {Some One},
title = {Something else},
year = {nodate},
url = {https://somesite.org/someotherpage},
urldate = {2017-12-19},
note = {I'm another note}
}

onlineelements isn't set up to print the note. What are you using the note field for, exactly? – Alan Munn Jan 07 '18 at 23:49urldatefield. See §4.2.2 of thebiblatex-apadocumentation. – Alan Munn Jan 08 '18 at 00:37@onlineentry type supports theaddendumfield. In contrast to thenotefield, theaddendumfield prints after theurlandurdate. But perhaps it would suit you. – David Purton Jan 08 '18 at 09:49urldateused for "retrieved on"? APA§4.2.2 actually also says so. What if you want both "Retrieved on:addendumcan be used. Where in the entry would the "Last Updated on" information go relative to other elements in the reference? I don't have the actual APA guide to find out. If it's where theaddendumshould go, then you're not gaining much with making a version for using thenotefield. – Alan Munn Jan 09 '18 at 01:04notefield. It just depends on the APA guidelines where things should go. – David Purton Jan 09 '18 at 01:27
