Biblatex：按年份划分子部分的参考文献列表（降序）

Question

我想创建一个从最新到最旧的参考文献列表。

下面的 MWE 给出了一个基本的解决方案：

\documentclass{article}
\usepackage[style=authoryear,sorting=ydnt]{biblatex}
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book{Rabelais1532,
  author = {Rabelais, Fran\c{c}ois},
  date = {1532},
  title = {Pantagruel},
  keywords = {1532},
}
@book{Hugo1862,
  author = {Hugo, Victor},
  date = {1862},
  title = {Les Mis\'{e}rables},
  keywords = {1862},
}
@book{Hugo1831,
  author = {Hugo, Victor},
  date = {1831},
  title = {Notre-Dame de Paris},
  keywords = {1831},
}
@book{Zola1885,
  author = {Zola, \'{E}mile},
  date = {1885},
  title = {Germinal},
  keywords = {1885},
}
@book{Balzac1831,
  author = {de Balzac, Honor\'{e}},
  date = {1831},
  title = {The Skin of Sorrow},
  keywords = {1831},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography[title=References (default)]
\end{document}

不过我想在列表中创建一些部分，每个部分对应一年，如下所示：

\printbibliography[keyword=1885, title=1885]
\printbibliography[keyword=1862, title=1862]
\printbibliography[keyword=1831, title=1831]
\printbibliography[keyword=1532, title=1532]

我试图在序言中定义过滤器，并根据文档biblatex（§3.7.9，第 89 页）进行了修改：

\defbibfilter{1885}{%
    date=1885
}%

并添加以下代码：

\printbibliography[filter=1885, title=1885]

但日志文件表明：

Package biblatex Error: Invalid filter expression.

Package biblatex Error: Filter '1885' not found.

例如，是否可以使用过滤命令，按照年份减少的顺序自动执行该过程？

Answer 1

我认为如果年份列表可以自动生成就更好了，这样你就不必写\printbibliography[keyword=1885, title=1885]等等了。

您的过滤器的问题是 不是date=1885有效的过滤器表达式。过滤器只能有(not)type、(not)subtype和(纯存在) 表达式。对于更复杂的过滤器(not)keyword，(not)field您需要bibcheck。事实上，这就是我们下面使用的。bibcheck thisyear检查条目是否可追溯到某一年份。

在这里我使用 LaTeX3 代码轻松地对所有年份的列表进行排序。
