我在写一篇很长的论文时遇到了 hyperref 问题。我必须经常引用一些参考文献，然后反向引用会变得比一行的宽度还要长。当这种情况发生时，我会遇到“Overfull \hbox”警告。人们很少在多页中引用一个参考文献，然而，这是我必须做的。当我继续工作时，反向引用编号（链接）会变长，并且不会分成多行，然后它就会成为一个问题（因为这个错误现在超出了页面边界）。我必须继续扩展我的文档页面（并且经常引用相同的参考文献）。有什么方法可以抑制警告，或者有命令强制将长反向引用分成多行？非常感谢！
这可能是 hyperref 的一个 bug。一般情况下，人们不会引用一个参考文献那么多次，但当你写长篇论文或书籍时，这是不可避免的。因此，如何创建多行 backref 很重要。

答案1
您正在将整个 backref 列表放入\textsuperscript：
\renewcommand*{\backrefalt}[4]{
\textcolor[rgb]{0,0,1} {\textsuperscript{ %<--------------------
\ifcase #1 (Not cited.) \ % not cited
\or \{p.~#2.\} % cited once
\else \{pp.~#2.\} % cited multiple pages
\fi%
}
}
}
\textsuperscript创建一个框。如果您想要较小的字体大小，请使用例如\scriptsize：
\renewcommand*{\backrefalt}[4]{%
\textcolor[rgb]{0,0,1} {\scriptsize
\ifcase #1 (Not cited.) \ % not cited
\or \{p.~#2.\} % cited once
\else \{pp.~#2.\} % cited multiple pages
\fi%
}}
然后给出
