同一作者的多个书籍条目的书目特定格式 - 解决方案怪癖

Question

这个问题与问题相关同一作者的多个书籍条目的书目特定格式，它有一个非常好的解决方案，但是当应用到我的数据时，出现了与作者相关的奇怪的怪癖。

一位作者的书目列表的第一个条目也应以与第二、第三...相同的格式出现，即它应从作者下方的行开始，并在其前面有一个破折号。这只适用于特殊格式的书目。但是，对于下面使用的参考书目，在同一作者的多个书籍条目的书目特定格式给出了奇怪的结果。为什么会这样？

以下是实际示例：

以及由此产生的特殊格式的参考书目的图像，其中相同的作者姓名出现多次。

Answer 1

正如评论中所解释的那样，这是因为 Biber v. <= 2.7在排序时author = {Gauck, Joachim}将其视为相同，因此“Joachim Gauck”和“Joachim Gauck et al.”排序为同一个名字。author = {Gauck, Joachim and others}

这是不受欢迎的，已在 Biber 2.8 版中修复，其中两个列表将按不同的名称排序。请参阅https://github.com/plk/biber/issues/177

下列几乎适用于 Biber 2.7。它基本上检查名称是否包含，如果包含and others，则附加适当的sortname，以便条目与不包含的名称分开排序。不幸的是，和and others似乎有点问题。参考书目可能应该使用和而不是破折号。namehashand othersfullhashnamehash
