APA 6：如何去掉“and [last author]”之前的逗号？

Question

我使用文档类 APA 6 ( \documentclass[man,a4paper,floatsintext,donotrepeattitle]{apa6}) 和 Biblatex ( \usepackage[style=apa,sortcites=true,sorting=nyt,backend=biber]{biblatex}) 来撰写论文。我将其调整为 APA 6 的德语设置，效果很好，但在以下情况下我无法删除逗号：

下面黄色突出显示的部分是我在德语引文版本中不需要的部分（对于英语 APA6，它是正确的）。有人知道如何去掉这些逗号（在文本和参考书目中）吗？

Answer 1

正如评论中所述，这个问题已在较新版本中得到修复biblatex-apa，但如果不升级的话，让它正常运行并不难。

您需要重新定义\finalandcomma语言ngerman：

\DefineBibliographyExtras{ngerman}{
  \def\finalandcomma{}
}

另外，我注意到您有ngerman作为babel语言，但您指示biblatex-apa使用german。它们不应该是一样的吗？

如果你想和代替&，然后将其添加到下面的 MWE 序言中：

\AtEveryCitekey{%
  \renewcommand{\finalnamedelim}{%
    \ifnum\value{liststop}>2 \finalandcomma\fi\addspace\bibstring{and}\space}}
\AtBeginBibliography{\renewcommand*{\finalnamedelim}{%
    \ifthenelse{\value{listcount}>\maxprtauth}
      {}
      {\ifthenelse{\value{liststop}>2}
        {\finalandcomma\addspace\bibstring{and}\space}
         {\addspace\bibstring{and}\space}}}}

这是我的 MWE。它适用于您的biblatex、biber和版本biblatex-apa。（它使用&代替和，但我认为你已经改变了其他事情来解决这个问题，因为&是硬编码的biblatex-apa。）
