使用 BibLaTex 提供带有数字和字母标签的多个参考书目

Question

我想使用两个独立的书目biblatex，其中一个用于自己的出版物，另一个用于其他出版物。前者应标有字母 [A]、[B]、...，后者标有数字 [1]、[2]、[3]。我在文件中的自己的出版物中插入了“own”.bib作为关键字。这是我的代码：

\documentclass{scrbook}
\usepackage[english]{babel}
\usepackage[backend=biber,
style=numeric-comp,
defernumbers=true
]{biblatex}

\RequireBibliographyStyle{standard}
\ExecuteBibliographyOptions{labelnumber}
\DeclareNameAlias{author}{default}
\DeclareNameAlias{editor}{default}
\DeclareNameAlias{translator}{default}

\DeclareFieldFormat{bibentrysetcount}{\mkbibparens{\mknumalph{#1}}}
\DeclareFieldFormat{labelnumberwidth}{\mkbibbrackets{#1}}
\DeclareFieldFormat{shorthandwidth}{\mkbibbrackets{#1}}
%\DeclareFieldFormat{labelnumber}{\mknumalph{#1}}

\defbibenvironment{ownpub}
  {\list
     {\printtext[labelnumberwidth]{%
    \printfield{prefixnumber}%
    \printfield{labelnumber}}}
     {\setlength{\labelwidth}{\labelnumberwidth}%
      \setlength{\leftmargin}{\labelwidth}%
      \setlength{\labelsep}{\biblabelsep}%
      \addtolength{\leftmargin}{\labelsep}%
      \setlength{\itemsep}{\bibitemsep}%
      \setlength{\parsep}{\bibparsep}}%
      \renewcommand*{\makelabel}[1]{\hss##1}}
  {\endlist}
  {\item}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@misc{albert,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  keywords = {own}
}
@misc{berta,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
@misc{cesar,
  author = {Cuthor, C.},
  year = {2003},
  title = {Charlie},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}
own pub: \cite{albert}
other: \cite{berta}
other: \cite{cesar}

\printbibliography[env=bibliography,notkeyword=own]

\printbibliography[env=ownpub,keyword=own,resetnumbers=true]

\end{document}

我复制了numeric.bbx定义以定义新的 bib 环境“ownpub”。到目前为止，它使用数字标签，显示两个书目，每个书目都以 [1] 开头。但是，当我尝试将环境切换ownpub为字母标签时（通过注释的\DeclareFieldFormat，用\mknumalph）， 的更改labelnumber是全局的，并且两个书目都获得了字母标签。

我怎样才能将第二个参考书目更改为字母标签？

Answer 1

你可以尝试

\DeclareFieldFormat{labelnumber}{\ifkeyword{own}{\mknumalph{#1}}{#1}}

keyword own用字母标签来标记条目。

在下面的 MWE 中，我删除了所有没有改变标准的修改

\documentclass{article}
\usepackage[english]{babel}
\usepackage[backend=biber,
  style=numeric-comp,
  defernumbers=true
]{biblatex}
\usepackage{hyperref}

\DeclareNameAlias{author}{default}
\DeclareNameAlias{editor}{default}
\DeclareNameAlias{translator}{default}

\DeclareFieldFormat{labelnumber}{\ifkeyword{own}{\mknumalph{#1}}{#1}}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@misc{albert,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  keywords = {own}
}
@misc{berta,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
@misc{cesar,
  author = {Cuthor, C.},
  year = {2003},
  title = {Charlie},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}
own pub: \cite{albert}
other: \cite{berta}
other: \cite{cesar}

\printbibliography[notkeyword=own]
\printbibliography[keyword=own,resetnumbers=true]
\end{document}
