我一直在使用 biblatex，并参考了本书中的一些答案。
缩写列表分为 4 个部分，其中 3 个部分为讨论的主要作者，另一个部分为其他主要文本
本书的书目分为 5 个子书目，其中 3 个为主要作者，1 个为其他主要文本，最后一个为次要文本。
一切正常，除了子围兜中出现了一些不必要的多余线条。下面是一个由 MWE 生成的示例，其中 Benacerraf & Putnam 的条目和 Berger 的条目之间有一条额外的线条：
不幸的是，MWE 有点长：

显然，问题并没有得到解决参考书目中出现多余的行
原因是，如果使用\printbibliography而不是 ，\chapter*{Bibliography}并且使用 5 个后续命令来打印子书目，则生成的没有子书目的书目不会有多余的行：
非常感谢您的帮助！
答案1
当你注意到以下情况时，你实际上已经接近自己调试这个问题了：
原因是，如果使用
\printbibliography而不是 ，\chapter*{Bibliography}并且使用后续 5 个命令来打印子书目，则生成的没有子书目的书目不会有多余的行。
这让我们找到了有问题的参考书目中唯一不同的东西，即检查secondarysource。我不确定为什么检查会在那里引入虚假空格，但显然确实如此，因为如果我们使用以下方法处理它们：
\defbibcheck{secondarysource}{%
\iffieldint{origyear}
{\ifnumgreater{\thefield{origyear}}{1936}
{}
{\skipentry}%
}
{\iffieldint{year}
{\ifnumgreater{\thefield{year}}{1936}
{}
{\skipentry}%
}
{\skipentry}%
}%
}
多余的线已经消失了。
