Are you sure you are using the latest version of the style? I get the following with your MWE:
That might be the duplicate AUTHOR
field in Two
and Three
. If I remove them to retain only the different fields I get
\documentclass{article}
\usepackage[style=apa]{biblatex}
\addbibresource{\jobname.bib}
\begin{filecontents}[force]{\jobname.bib}
@BOOK{One,
AUTHOR = {Author Red and Author Green and Author Blue},
TITLE = {Title One},
DATE = {2019},
PUBLISHER = {Publisher},
}
@BOOK{Two,
AUTHOR = {Author Red and Author Yellow and Author Green and Author Blue},
TITLE = {Title Two},
DATE = {2020},
PUBLISHER = {Publisher},
}
@BOOK{Three,
AUTHOR = {Author Red and Author Green and Author Blue and Author Black},
TITLE = {Title Three},
DATE = {2021},
PUBLISHER = {Publisher},
}
\end{filecontents}
\begin{document}
\parencite{One,Two,Three}
\printbibliography
\end{document}
(Red et al., 2019; Red et al., 2021; Red et al., 2020) Red, A., Green, A., & Blue, A. (2019). Title one. Publisher. Red, A., Green, A., Blue, A., & Black, A. (2021). Title three. Publisher. Red, A., Yellow, A., Green, A., & Blue, A. (2020). Title two. Publisher.
Yes, please remove the duplicate AUTHOR
fields. Thanks.
I can reproduce now too but I am not so sure about the interpretation of that part of the manual, I think the implication is
"In the case of multiple works [by the same list of authors] in which some author names have been abbreviated to “et al.” (see Section 8.17), place the citations in chronological order (regardless of the order in which they appear in the reference list)."
and so the current behaviour is correct since (Red et al., 2019, 2020, 2021)
is misleading, implying that the same list of authors wrote 3 papers in different years.
I'm pretty sure rmolina is right. (There is no need for the duplicate author field, so I'm referring to moewew's MWE.) To reiterate, APA manual p. 263 says "In the case of multiple works in which some author names have been abbreviated to 'et al.' (see Section 8.17), place the citations in chronological order (regardless of the order in which they appear in the reference list)."
I don't think this implies "In the case of multiple works [by the same list of authors]" as plk suggests. In the case of multiple works by the same list of authors there wouldn't be the need for this clarification note. In-text citation order and reference list order simply cannot differ in such a case because if all the authors are identical, the next criterion for ordering is the date, and so in-text order and reference list order would be sorted by date and thus would be identical.
The only time the order in which references appear in the reference list may differ from the order in text is when subsequent authors differ. In the reference list, they are printed in full and sorted in alphabetical order of the authors. In text, the authors may be abbreviated to "first author et al." and thus potentially can be sorted in a different way.
The argument that "(Red et al., 2019, 2020, 2021) is misleading, implying that the same list of authors wrote 3 papers in different years" would only make sense if the APA manual would suggest such an ordering in order to enable one to differentiate between ambiguous cases. However, such an ordering is not suited for an unambiguous differentiation. Consider slightly different references: Red, A., Green, A., & Blue, A. (2019). Title one. Publisher. Red, A., Green, A., Blue, A., & Black, A. (2020). Title three. Publisher. Red, A., Yellow, A., Green, A., & Blue, A. (2021). Title two. Publisher. This would result in the in-text citation (Red et al., 2019, 2020, 2021) even though the authors are not identical. (Red et al., 2019, 2020, 2021) does not imply that the same list of authors wrote 3 papers in different years. We simply cannot tell whether these references are written by identical authors or not when only looking at the in-text citation. We need to look at the references in the reference list for that. All the in-text citation needs to do is enable one to clearly identify to which reference in the reference list an in-text citation is referring to. This is what section 8.18 is about.
So TL,DR: rmolina is right, Red, A., Green, A., & Blue, A. (2019). Title one. Publisher. Red, A., Green, A., Blue, A., & Black, A. (2021). Title three. Publisher. Red, A., Yellow, A., Green, A., & Blue, A. (2020). Title two. Publisher. should be sorted (Red et al., 2019, 2020, 2021), not (Red et al., 2019; Red et al., 2021; Red et al., 2020).
I'm not sure either of these solutions are correct. The uniquelist
expansion mandated in 8.18 should result in:
(Red, A. Green, A. & Blue, A. 2019; Red, A. Yellow, A. et al 2020; Red, A. Green, A., Blue, A. & Black, A. 2021)
It is mandated to expand the lists to the point of non-ambiguity with other lists. This necessity is in fact why I implemented the uniquelist
feature in the first place. If we can agree on the correct solution, I will have a look at what is going on.
(Red, A. Green, A. & Blue, A. 2019; Red, A. Yellow, A. et al 2020; Red, A. Green, A., Blue, A. & Black, A. 2021)
looks odd to me. Why print the initials?
I don't think 8.18 is relevant here. It's all about whether the in-text citations are unique enough to identify the exact reference in the reference list. With the three references mentioned, that is,
Red, A., Green, A., & Blue, A. (2019). Title one. Publisher. Red, A., Green, A., Blue, A., & Black, A. (2021). Title three. Publisher. Red, A., Yellow, A., Green, A., & Blue, A. (2020). Title two. Publisher.
all of them are unique, even if they are abbreviated to "(Red et al., 2019, 2020, 2021)" because each of them is published in a different year.
On the other hand, section 8.18 would apply if all them were published in the same year. So
Red, A., Green, A., & Blue, A. (2021). Title one. Publisher. Red, A., Green, A., Blue, A., & Black, A. (2021). Title three. Publisher. Red, A., Yellow, A., Green, A., & Blue, A. (2021). Title two. Publisher.
should result in the following in-text citation: "(Red, Green, & Blue, 2021; Red, Green, Blue, & Black, 2021; Red, Yellow, et al., 2021)".
Sorry, yes, there is no need for the initials, just copy-pasting without thinking. The key in 8.18 seems to be to be the phrase "shorten to the same form". It is true that the examples are all in the year.
I'm contacting the APA about this to get clarification. They are usually helpful when asked as I've had to do this before for similar questions.
I agree, "shorten to the same form" is the key. Alright, let's see what they will tell us.
They have replied and you are correct, with different years, it's:
(Red et al., 2019, 2020, 2021)
with identical years the list disambiguation applies:
(Red, Green, & Blue, 2021; Red, Green, Blue, & Black, 2021; Red, Yellow, et al., 2021)
so I will look into this.
It's so long since I looked at this, looking that the style doc now, I already interpreted that clause correctly and explicitly put in a test for this some time ago (see p. 6 of the style examples PDF) so it seems that the issue is in the multicite variant so something still needs to be looked at.
This will be fixed in the next release. It's interesting that the fix was a reversion of a legacy fix for a different issue that was resolved another way some time ago and the legacy fix was now in fact the cause of this issue.
Oh, they replied so fast. You are right, it's even already in the style examples PDF. So basically, this was already implemented but you disimproved it along the way, right? I cannot even imagine how much code the APA style needs. The style is so complex. Anyway, thanks for fixing it. I'm looking forward to testing it once it's out. Keep up the good work!
It was already implemented but I hadn't tested multicites in that scenario and had an old fix for something that was no longer an issue which made it not work. It is a beast of a style and made me take on biber
in the first place as the auto-expansion of name lists was a requirement and biblatex
couldn't do that with bibtex
...
Please consider the following MWE:
This code results in the citation
(Red et al., 2019; Red et al., 2021; Red et al., 2020)
. I believe this should be(Red et al., 2019, 2020, 2021)
.I could not find anything specific about this case (ambiguous compression of multiple authors) in the Publication Manual. Still, at the end of Section 8.12, it says: In the case of multiple works in which some author names have been abbreviated to “et al.” (see Section 8.17), place the citations in chronological order (regardless of the order in which they appear in the reference list).
I think this clarification note is precisely about this case. If this were about multiple works from the same authors, we would use chronological order anyway because they get chronologically sorted in the reference list. In such a case, we would not need this clarification.
What do you think?
EDIT: removed duplicated AUTHOR fields.
