如何在 biblatex 中引用第一次出现的引文

Question

如何才能获得某个条目首次被引用的脚注编号\ifciteseen？

梅威瑟：

\documentclass{article}

\usepackage[
    backend=biber,
    citetracker=true,
]{biblatex}

\addbibresource{biblatex-examples.bib}

\renewbibmacro*{cite}{%
    \printnames{labelname}
    \setunit{\nametitledelim}
    \ifciteseen{%
        \printfield{shorttitle}%
        \printtext{\addspace(seen in footnote~\ldots)}
    }{%
        \printfield{title}
    }
}

\begin{document}

\footcite{angenendt}
\footcite{angenendt}

\end{document}

我们可以从verbose-note.cbx

“在脚注中看到”位可以通过seenotebibstring进行国际化

\DefineBibliographyStrings{english}{seenote = {seen in footnote}}
