If I want to add the numbering for a book in a series, which field should be used?
texdoc bibtex, it says
number The number of a journal, magazine, technical report, or of a work in a series.
volume The volume of a journal or multivolume book.
texdoc biblatex, it says
number The number of a journal or the volume/number of a book in a series.
volume The volume of a multi-volume book or a periodical.
It seems that both bibtex and biblatex recommend using the field
number for the designation of a book in the book series.
But usually these two fields will be formatted as "No. xx" and "Vol. xx` for book entries.
Now I am confused, which one should I use in general? Or there is no general choice and it depends on the style in use?
