我正在处理有关以 APA 风格引用和引用来源的问题。
这是我的示例代码：
\documentclass[a4paper,
12pt,
bibtotoc,
liststotoc,
pointlessnumbers
]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage[american,ngerman]{babel}
\usepackage[babel=true]{csquotes}
\usepackage[style=apa,backend=biber, doi=false, url=false]{biblatex}
\DeclareLanguageMapping{ngerman}{ngerman-apa}
\DefineBibliographyStrings{ngerman}{andothers={et\ \addabbrvspace al\adddot}}
\renewcommand\finalandcomma{\addcomma}
\usepackage{filecontents}
\begin{filecontents}{literatur.bib}
@article{DroitVolet2007,
author = {Droit-Volet, S. and Meck, W. H.},
year = {2007},
title = {{H}ow emotions colour our perception of time},
pages = {504--513},
volume = {11},
number = {12},
issn = {13646613},
journal = {Trends in Cognitive Sciences},
doi = {10.1016/j.tics.2007.09.008 Titel anhand dieser DOI in Citavi-Projekt übernehmen
}
@article{Gibbon1984,
author = {Gibbon, J. and Church, R. M. and Meck, W. H.},
year = {1984},
title = {{S}calar timing in memory},
pages = {52--77},
volume = {423},
issn = {0077-8923},
journal = {Annals of the New York Academy of Sciences}
}
}
\end{filecontents}
\bibliography{literatur}
\begin{document}
There is no comma in this citation \parencite{DroitVolet2007}, but the comma is missing in the references.
For more than two authors there has to be a comma in front of & \parencite{Gibbon1984}.
\printbibliography
\end{document}
当只有两位作者时，Latex 在参考文献部分的 & 前面漏了一个逗号。对于两位作者，文内引用完全没问题，但参考文献中的条目应如下所示：Droit-Volet, S., & Meck, WH (2007)。...
对于两位以上的作者，在正文引用中 & 前面也必须有一个逗号。
在寻找解决方案时，我尝试使用以下方法修复它
\renewcommand*{\finalnamedelim}{%
\finalandcomma
\addspace
\bibstring{and}%
\space
}
或者
\renewcommand\finalandcomma{\addcomma}
但不幸的是，这两种解决方案对我来说都不起作用......
如果您能提供任何帮助或建议我们将不胜感激。
祝一切顺利，费迪南德
答案1
由于某种原因，在钩子中biblatex-apa重新定义。\finalnamedelim\AtBeginBibliography
因此，我们必须执行相同的操作来覆盖设置；此外，我们\finalandcomma在\AtBeginDocument钩子中重新定义
\AtBeginDocument{\renewcommand\finalandcomma{\addcomma}}
\AtBeginBibliography{%
\renewcommand*{\finalnamedelim}{%
\ifthenelse{\value{listcount}>\maxprtauth}
{}
{\finalandcomma\addspace\&\space}}}
这总是会打印\finalandcomma（通常只有在有两个以上的作者时才会打印）。

抑制\renewcommand{\finalandcomma}{\addcomma}（在 apa 样式中，\finalendcomma 打印一个 & 符号，而您想保留它）。在序言中将其替换为以下内容：
\usepackage{xpatch}
\xpatchnameformat{apaauthor}{%
{\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{}}%
{%
{\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{\addcomma\space}}%
{}{}%
