使用 bibtex 后端动态添加多个 bib 文件

我正在编写一份大型文档，其中包含许多论文，其参考书目结构如下：

/ch1
--paper1.tex
--paper1.bib
--paper1-extra.bib
/ch2
--paper2.tex
--paper2.bib
...
document.tex

我想要做的是在每个 paper*.tex 源中动态地包含 bib 源（类似于addbibresource），而不是将这样的命令放入根 document.tex 文件中：

\bibliography{ch1/paper1,paper1-extra,ch2/paper1,...}

我的构建脚本是这样的：

pdflatex document
bibtex document
pdflatex document
pdflatex document

有没有办法使用 bibtex 后端来完成它？

该命令\bibliography有两个作用：它的参数告诉 BibTeX 在哪里寻找参考文献，并且打印 BibTeX 生成的参考书目。

可以将这两项工作拆分为两个新命令。在下面的示例中，我们定义了一个\printbibliography仅打印参考书目的命令和一个\addbibfile可在文档的任何位置多次使用的命令，用于将.bib文件列表添加到 BibTeX 应查看的文件列表中。的语法\addbibfile与的参数的语法相同\bibliography：您可以给出一个不带扩展名的逗号分隔的文件名列表.bib。给定的文件名将\addbibfile被收集并写入.aux文档末尾的 BibTeX 中。

MWE（假设有一个简单的参考书目设置，并且没有任何\inputs 和\includes，因为它们对于此处提供的代码实际上并不重要）

来自两个不同文件的引文和参考书目

请注意，此解决方案仅生成一个与正常相同的全局书目\bibliography。对于与和朋友的拆分书目，必须进行额外的工作multibib。
