抑制期刊文章的月份和日期并保留报纸文章的月份和日期

Question 1

魔法条件语句可以使用以下方式构建etoolbox's \ifboolexpr(etoolbox由biblatex；另请参阅etoolbox手动的和biblatex文档，特别是§4.6.3测试\ifboolexpr和\ifthenelse，第 179 页）。

我们\ifboolexpr可以使用biblatex（参见独立测试，第 171-179 页biblatex文档)：我们只需test在测试前添加一个，并将命令括在花括号中，我们还省略了“真”和“假”分支。所以\iffieldundef{volume}{true}{false}变成了\ifboolexpr{test {\iffieldundef{volume}}}{true}{false}；的妙处\ifboolexpr在于我们可以使用逻辑运算符来连接表达式。

在本例中，我们有

\AtEveryBibitem{%
  \ifboolexpr{test {\ifentrytype{article}} and (not test {\iffieldundef{number}} or not test {\iffieldundef{volume}})}
    {\clearfield{month}%
     \clearfield{day}}
     {}%
}

这将删除具有或字段的month和day字段（或两者，因为是逻辑上的包含或）。@articlesnumbervolumeor

您还可以利用该entrysubtype字段，只需添加到来自报纸的entrysubtype = {newspaper}每个条目中（令人惊讶的是）。@article

@article{test1,
  title         = {Ideas \& trends; politics of the web: {Meet}, greet, segregate, meet again},
  url           = {http://www.nytimes.com/2004/01/25/weekinreview/ideas-trends-politics-of-the-web-meet-greet-segregate-meet-again.html},
  urldate       = {2014-01-14},
  journal       = {New {York} {Times}},
  author        = {Harmon, Amy},
  day           = {01},
  month         = jan,
  year          = {2004},
  entrysubtype  = {newspaper},%<---- here it is
}

然后我们使用条件

\AtEveryBibitem{%
  \ifboolexpr{test {\ifentrytype{article}} and not test {\iffieldequalstr{entrysubtype}{newspaper}}}
    {\clearfield{month}%
     \clearfield{day}}
    {}%
}

删除month并且day从中@articles不存在newspaper @articles。

Question 2

新的吸水工程为 OP 的要求提供了另一种解决方案。虽然 Bibulous 可以检查是否存在充当标志的字段（在 @moewe 提供的 BibLatex 解决方案中，使用该entrysubtype字段），但 Bibulous 的一个更简洁的解决方案是简单地为报纸文章定义一个新的条目类型，以将其与期刊文章区分开来。因此，使用以下数据库文件main.bib

@newsarticle{test1,
  title = {Ideas \& trends; politics of the web: {Meet}, greet, segregate, meet again},
  url = {http://www.nytimes.com/2004/01/25/weekinreview/ideas-trends-politics-of-the-web-meet-greet-segregate-meet-again.html},
  urldate = {2014-01-14},
  journal = {New York Times},
  author = {Harmon, Amy},
  day = {1},
  month = jan,
  year = {2004}
}

@article{test2,
  title = {Social movement networks virtual and real},
  volume = {3},
  issn = {1369-118X},
  url = {http://www.tandfonline.com/doi/abs/10.1080/13691180051033333},
  doi = {10.1080/13691180051033333},
  number = {3},
  urldate = {2013-05-31},
  journal = {Information, Communication \& Society},
  author = {Diani, Mario},
  month = jan,
  year = {2000},
  pages = {386--401}
}

我们可以开发一个 Bibulous 格式的样式文件，main.bst例如

TEMPLATES:
article = <au> (<year>). <title>. \textit{<journal>} \textit{<volume>}(<number>),{ }...
          [<startpage>--<endpage>|<startpage>|<eid>|].[ doi:\url{<doi>}| url:\url{<url>}]
newsarticle = <au> (<year>, <month.monthname()> <day>). <title>.{ }...
          \textit{<journal>}. Retrieved <urldate>, from \url{<url>}.

SPECIAL-TEMPLATES:
authorlist = <author.to_namelist()>
editorlist = <editor.to_namelist()>
au = <authorlist.format_authorlist()>
ed = <editorlist.format_editorlist()>
citelabel = (<authorlist.0.last>, <year>)

OPTIONS:
namelist_format = last_name_first

（上面的块显示了整个样式文件。）最后，我们需要重新定义\@biblabel和\@cite宏，以使 Latex 在文本中使用正确的引用标签。因此，main.tex文件将如下所示

\documentclass{article}
\usepackage[paper=letterpaper, text={6.2in,8.5in},centering]{geometry}
\usepackage[colorlinks=True,urlcolor=blue,citecolor=black,breaklinks=true]{hyperref}

\makeatletter
   \renewcommand{\@biblabel}[1]{}
   \renewcommand{\@cite}[2]{{#1\if@tempswa , #2\fi}}
\makeatother

\begin{document}

Lorem \cite{test1} ipsum \cite{test2}.

\bibliography{example9}
\bibliographystyle{example9}

\end{document}

编译后，将生成如下所示的格式化的参考列表：
