A bibliography with entries in several scripts
For non-Roman scripts, it's common to have separate bibliographies. I imagine that this was especially the case when switching languages required switching codesets or linotype font sets. 

So you'd have:


English language bibliography
Chinese language bibliography


and so forth. There's even a question on the TeX.stackexchange on how to do this: https://tex.stackexchange.com/questions/343307/put-chinese-language-entries-before-english-language-entries-in-the-bibliography

These days, it's easy to mix the two together as unicode solved many of the font issues. But separating them allows you to use the name ordering system most appropriate for that language.
