我正在使用以下内容：
\documentclass{article}
\usepackage[american]{babel}
\usepackage{filecontents}
\usepackage[style=authoryear,%
natbib=true, % enable natbib macros
%firstinits=true, % use initials as first names
dashed=false, % do not use a dash instead of author name in case of several publications
useprefix=true,
maxnames=100, % in the bibliography show all names
maxcitenames=2, % in the text use et al. for more than 2
backref=true, % have backrefs in the bibliography
]{biblatex}
\setlength\bibitemsep{1mm}
\setlength\bibhang{1cm}
%print authors in smallcaps everywhere
\renewcommand*{\mkbibnamelast}[1]{%
\ifmknamesc{\textsc{#1}}{#1}}
\renewcommand*{\mkbibnameprefix}[1]{%
\ifboolexpr{ test {\ifmknamesc} and test {\ifuseprefix} }
{\textsc{#1}}
{#1}}
\def\ifmknamesc{%
\ifboolexpr{ test {\ifcurrentname{labelname}}
or test {\ifcurrentname{author}}
or ( test {\ifnameundef{author}} and test {\ifcurrentname{editor}} ) }}
\begin{filecontents}{\jobname.bib}
@Article{gillies,
author = {Gillies, Alexander and Mister Miller},
title = {Herder and the Preparation of Goethe's Idea of World Literature},
journaltitle = {Publications of the English Goethe Society},
volume = {9},
date = {1933},
pages = {46--67}}
\end{filecontents}
\addbibresource{\jobname.bib}
\begin{document}
\citep{gillies}
\printbibliography
\end{document}
然而这给出了：
GILLIES, Alexander and Mister MILLER (1933). “Herder and the Preparation of Goethe’s Idea of World Literature.” In: Publications of the English Goethe Society 9, pp. 46–67 (cit. on p. 1).
但我想要：
GILLIES, Alexander, and Mister MILLER (1933). “Herder and the Preparation of Goethe’s Idea of World Literature.” In: Publications of the English Goethe Society 9, pp. 46–67 (cit. on p. 1).
我如何添加逗号？
答案1
在您的序言中添加：
\renewcommand*{\finalnamedelim}{%
% \ifnumgreater{\value{liststop}}{2}{\finalandcomma}{}% DELETED
\finalandcomma% ADDED
\addspace\bibstring{and}\space}
或者如果您不想在引用中添加逗号：
\AtBeginBibliography{%
\renewcommand*{\finalnamedelim}{%
% \ifnumgreater{\value{liststop}}{2}{\finalandcomma}{}% DELETED
\finalandcomma% ADDED
\addspace\bibstring{and}\space}%
}
第二种变体的输出：
