使用最新版本的 biblatex（和 biber 2.0）

Question

我必须在文档中创建两个参考书目（简单），它们应该被编号（简单），并由不同的\cite命令填充（例如，可以使用类别来完成）。问题是，一些书目条目可能应该同时出现在两个参考书目中，问题就从这里开始，正如这个例子所示：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[style=numeric,defernumbers,sortcites]{biblatex}
\DeclareBibliographyCategory{related}
\DeclareBibliographyCategory{main}

\DeclareCiteCommand{\cite}[\mkbibbrackets]
  {\usebibmacro{prenote}}
  {\addtocategory{main}{\thefield{entrykey}}%
   \usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\DeclareCiteCommand{\citer}[\mkbibparens]
  {\usebibmacro{prenote}}
  {\addtocategory{related}{\thefield{entrykey}}%
   \usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\addbibresource{biblatex-examples.bib}  

\begin{document}
\cite{shore,sarfraz,spiegelberg}

\citer{spiegelberg}

\cite{weinberg}

\citer{sigfridsson}


\printbibliography[category=main,title=Main List,resetnumbers]

\DeclareFieldFormat{labelnumberwidth}{\mkbibparens{#1}}
\printbibliography[category=related,resetnumbers,title=Related Documents]

\end{document}

Spiegelberg 条目在第一个参考书目中应为 3（并且当被 引用时）\cite，在第二个参考书目中应为 2（当被 引用时）\citer。我现在已经查看了refsection（如果可以“中断并继续”，则可行）、\DeclareSourceMap（复制条目）和其他内容，但看起来没有什么效果。有人知道该怎么做吗？

我找到了两个解决方案

使用最新版本的 biblatex（和 biber 2.0）

可以“克隆”条目：（另请参阅https://github.com/plk/biblatex/issues/297）

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[style=numeric,defernumbers,sortcites]{biblatex}
\DeclareBibliographyCategory{related}
\DeclareBibliographyCategory{main}

\DeclareCiteCommand{\cite}[\mkbibbrackets]
  {\usebibmacro{prenote}}
  {\addtocategory{main}{\thefield{entrykey}}%
   \usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\DeclareCiteCommand{\citer}[\mkbibparens]
  {\usebibmacro{prenote}}
  {\addtocategory{related}{\thefield{entrykey}}%
   \usebibmacro{citeindex}%
   \usebibmacro{cite}}
  {\multicitedelim}
  {\usebibmacro{postnote}}

\addbibresource{biblatex-examples.bib}

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \perdatasource{biblatex-examples.bib}
      \step[fieldsource=entrykey, match=\regexp{(.*)}, final]
      \step[entryclone={rel-$1}]
    }
  }
}

\begin{document}\nocite{*}
\cite{shore,sarfraz,spiegelberg}

\citer{rel-spiegelberg,rel-springer}

\printbibliography[category=main,title=Main List,resetnumbers]

\DeclareFieldFormat{labelnumberwidth}{\mkbibparens{#1}}
\printbibliography[category=related,resetnumbers,title=Related Documents]

\end{document}

使用“分割重新切片”

这会将不同的引用命令放在不同的引用部分中。这里的挑战是找到一种暂停和重新启动引用部分的方法。由于引用部分不能嵌套，因此无法在具有“真实”引用部分的文档中使用此解决方案！有关此解决方案的讨论在此处https://github.com/plk/biblatex/issues/307。如果我有时间我可能会把它转换成一个包。

2018 年更新以适应一些内部变化\blx@refsection@i。
