APA 引用中未显示月份

Question

我正在使用 biblatex-apa，此示例应将月份放在年份后面，如 (Gilbert, 1987, may)，但我得到的却是 (Gilbert, 1987)。

\RequirePackage{filecontents}

\begin{filecontents*}{mybib.bib}
@article{gilbert87,
    title = {Terrifying guitar 101},
    journal = {Guitar player},
    author = {Gilbert, Paul},
    month = may,
    year = {1987},
    pages = {99}
}
\end{filecontents*}

\documentclass[a4paper]{article}

\usepackage[
    style=apa,
    backend=biber
]{biblatex}

\usepackage[utf8]{inputenc}
\usepackage{csquotes}

\usepackage[british]{babel}
\DeclareLanguageMapping{british}{british-apa}

\addbibresource{mybib.bib}

\begin{document}

Here is som text \parencite{gilbert87}.

\printbibliography
\end{document}

Answer 1

gilbert88通过在文件中添加第二个 bib 条目，bib例如

@article{gilbert88,
    title   = {Terrifying guitar 101},
    journal = {Guitar player},
    author  = {Gilbert, Paul},
    date    = {1988-05},
    pages   = {100},
}

使用biblatex符合date字段，而不是旧的year和month字段（date = {1988-05}），你得到以下 MWE

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@article{gilbert87,
    title   = {Terrifying guitar 101},
    journal = {Guitar player},
    author  = {Gilbert, Paul},
    month   = may,
    year    = {1987},
    pages   = {99},
}
@article{gilbert88,
    title   = {Terrifying guitar 101},
    journal = {Guitar player},
    author  = {Gilbert, Paul},
    date    = {1988-05},
    pages   = {100},
}
\end{filecontents*}


\documentclass[a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[british]{babel}

\usepackage{csquotes}
\usepackage[%
    style=apa,
    backend=biber
]{biblatex}
\DeclareLanguageMapping{british}{british-apa}
\addbibresource{\jobname.bib}


\begin{document}

Here is some text~\parencite{gilbert87} and~\parencite{gilbert88}.

\printbibliography
\end{document}

结果如下：

如您所见，字段中带有年份 1988 的新书目条目date = {1988-05}提供了您想要的书目条目。

要显示月份，\parencite您需要使用 重新定义该命令\DeclareCiteCommand{\parencite}。

请参阅以下 MWE

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@article{gilbert87,
    title   = {Terrifying guitar 101},
    journal = {Guitar player},
    author  = {Gilbert, Paul},
    month   = may,
    year    = {1987},
    pages   = {99},
}
@article{gilbert88,
    title   = {Terrifying guitar 101},
    journal = {Guitar player},
    author  = {Gilbert, Paul},
    date    = {1988-05},
    pages   = {100},
}
\end{filecontents*}


\documentclass[a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[british]{babel}

\usepackage{csquotes}
\usepackage[%
    style=apa,
    backend=biber
]{biblatex}
\DeclareLanguageMapping{british}{british-apa}
\addbibresource{\jobname.bib}

\DeclareCiteCommand{\parencite}[\mkbibparens]%
  {\usebibmacro{cite:init}%
   \usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{cite}\setunit{\nameyeardelim}\printfield{month}} % <============
  {}
  {\usebibmacro{postnote}%
   \usebibmacro{cite:post}}


\begin{document}

Here is some text~\parencite{gilbert87} 
and~\parencite[prenote][postnote]{gilbert88} 
and~\parencite*[prenote][postnote]{gilbert88}.

\printbibliography
\end{document} 

结果：
