# How to make the author field bold, including the conjunction “and” in Biblatex? [duplicate]

I am using style = authoryear in Biblatex and I want to make all author names, including the conjunction "and" in bold. I have used the following commands

\renewcommand{\mkbibnamefirst}[1]{\textbf{#1}}
\renewcommand{\mkbibnamelast}[1]{\textbf{#1}}


however this only makes the author names bold but not the "and" conjunction, so I get something like this

How can I make the "and" and the commas bold in the author field?

• Seeing that you just copied the approach from the other answer, I would prefer to vote to close as a duplicate of Make author names bold in bibliography only. WOuld that be OK with you. – moewe Jun 2 '15 at 6:01

This answer is from the following post.

\DeclareNameFormat{last-first/first-last-bold}{\mkbibbold{%
\ifnumequal{\value{listcount}}{1}
{\iffirstinits
{\usebibmacro{name:last-first}{#1}{#4}{#5}{#7}}
{\usebibmacro{name:last-first}{#1}{#3}{#5}{#7}}%
\ifblank{#3#5}
{}
{\usebibmacro{name:revsdelim}}}
{\iffirstinits
{\usebibmacro{name:first-last}{#1}{#4}{#5}{#7}}
{\usebibmacro{name:first-last}{#1}{#3}{#5}{#7}}}%
\usebibmacro{name:andothers}}}
\DeclareNameAlias{sortname}{last-first/first-last-bold}
