带注释的参考书目：两个参考书目，标签打印不正确

Question

\assignrefcontextentries[<refcontext>]{<entrykey>}只能去现存的的引用上下文<entrykey>。如果某条目打印在该引用上下文中的参考书目中，则该条目存在引用上下文。

由于您发出了\assignrefcontextentries*[<refcontext>]{*}，因此 refcontext 必须对所有条目有效。

以下简化的示例显示了正在发生的事情

\documentclass{article}
\usepackage{blindtext}
\usepackage[backend=biber, style=numeric-comp, sorting=ynt, defernumbers]{biblatex}

\assignrefcontextentries*[sorting=nyt, labelprefix=A]{*}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,geer,nussbaum}

\printbibliography[title={\texttt{sorting=ynt}}]

\newrefcontext[sorting=nyt, labelprefix=A] 
\printbibliography[title={\texttt{sorting=nyt, labelprefix=A}}]
\end{document}

编译成功并生成

相似地

\documentclass{article}
\usepackage{blindtext}
\usepackage[backend=biber, style=numeric-comp, sorting=ynt, defernumbers]{biblatex}

\assignrefcontextentries*[sorting=ynt]{*}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,geer,nussbaum}

\printbibliography[title={\texttt{sorting=ynt}}]

\newrefcontext[sorting=nyt, labelprefix=A] 
\printbibliography[title={\texttt{sorting=nyt, labelprefix=A}}]
\end{document}

工作和生产

这些示例符合预期，因为在两种情况下，所使用的 refcontexts 都\assignrefcontextentries存在于所有条目中。

如果我们选择一个不存在的 refcontext（sorting=nyt没有labelprefix），我们最终会得到

\documentclass{article}
\usepackage{blindtext}
\usepackage[backend=biber, style=numeric-comp, sorting=ynt, defernumbers]{biblatex}

\assignrefcontextentries*[sorting=nyt]{*}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,geer,nussbaum}

\printbibliography[title={\texttt{sorting=ynt}}]

\newrefcontext[sorting=nyt, labelprefix=A] 
\printbibliography[title={\texttt{sorting=nyt, labelprefix=A}}]
\end{document}

对于你的例子，这意味着你需要

\assignrefcontextentries*[sorting=ynt]{*}

代替

\assignrefcontextentries*[sorting=nyt, labelprefix=A]{*}

您不仅需要删除labelprefix，还需要更改排序。这样做的原因与上面的简化示例一样，refcontextsorting=nyt本身并不存在。

\documentclass{amsart}
\usepackage{blindtext}
\usepackage[backend=biber, style=numeric-comp, sorting=ynt, defernumbers]{biblatex}
\usepackage{hyperref}

\assignrefcontextentries*[sorting=ynt]{*}
