问题：我需要两个书目，第一个采用字母格式并按作者姓名排序。第二个采用数字格式并按引用顺序排序。两者没有共同的参考文献。不知何故我在 biblatex 中搜索了类似这样的内容：
\bibliographystyle{style = alphabetic}
\printbibliography{books.bib}
\bibliographystyle{style = numerical, sorting = none}
\printbibliography{links.bib}
我以为 biblatex 是专门为处理多个参考书目而编写的，但我没有找到除了 MWE 中显示的方法（这显然是一种 hack）之外的任何其他方法。实际上，它工作得很好，直到我想要另一种排序方式。当我使用
\newrefcontext[sorting=none]
引用数量变为零。
答案1
如果您将该选项传递labelnumber给，biblatex您甚至可以使用数字引用style=alphabetic。
cite 命令可以根据关键字进行切换，因此\cite无论如何您都可以对所有条目使用keyword。
对于数字书目，我们必须定义一个新的书目环境来打印数字引用。bibliographyNUM直接从中复制numeric.bbx。要设置书目的排序，只需说
\newrefcontext[sorting=none]
\printbibliography[env=bibliographyNUM, title=References, keyword=secondary, resetnumbers]
在数字书目之前。前一个书目将使用anyt适合字母样式书目的全局排序方案。如果有必要将排序方案分配保持在本地（因为数字书目位于字母书目之前），则可以使用
\begin{refcontext}[sorting=none]
\printbibliography[env=bibliographyNUM, title=References, keyword=secondary, resetnumbers]
\end{refcontext}

非常感谢。我想分享我对这个问题的改编版本。我通过定义不同的引用词将我的 Bib 分为几类。它是从 Driftnet 来源复制而来的，尤其是biblatex：按不同的 .bib 文件分类的多个参考书目所以这不是最佳实践，但它确实有效。希望 biblatex 将来能够原生支持混合参考书目样式。

答案3
按照@moewe 所说的使用数字引用style=alphabetic。
对于不同的排序顺序，有一种更简单的方法，即refcontext环境，它采用排序选项。首先，使用 Biblatex 生成主要参考书目：
\printbibliography[title=Bibliography, keyword=primary]
refcontext然后，通过将其括在作为参数的文件中，创建具有不同排序、过滤器和样式的第二个文件。
\begin{refcontext}[sorting=ydnt]{} % sort chronologically
\printbibliography[title=References, keyword=secondary, resetnumbers]
\end{refcontext}
{}最后一个参数为空，refcontext可让您创建一个临时环境，而无需在其他地方声明任何内容。
当我的学校要求我在论文结尾处附上简历时，我就用了这个，因此除了论文中通常的 AZ 书目外，我还需要按时间倒序生成我的作品书目。它比我以前做的要干净得多。
