# make all author names in bibliography (chicage style) bold and make the bibliography title “reference” not bold

I am using the following code for my latex project:

        \usepackage[authordate, maxcitenames=3,
backend=biber]{biblatex-chicago}


and

    \printbibliography[
title={REFERENCES}
]


I want to all the author names in the bibliography bold. And at the same time, the title word "Referece" of the bibliography not bold. I searched a lot, but failed to find a solution, can someone help? any help will be greatly appreciated.

• Those are two completely orthogonal questions. I suggest you ask separate questions about them (see also tex.meta.stackexchange.com/q/7425/35864). – moewe Feb 23 at 7:43
• For the bibliography heading the solution will also depend on your document class and other modifications you are applying to headings. \printbibliography typesets its heading with a normal \section* or \chapter* command that is formatted like all similar commands in the document. If you want the bibliography heading to behave differently from normal chapter headings, additional work is needed. – moewe Feb 23 at 7:44

The formatting of the bibliography heading will depend on the document class (and other things), which you haven't shown us. So I will try to answer the question about bold names and encourage you to ask a new question about the bibliography heading with a compilable example document (an MWE: I've just been asked to write a minimal working example (MWE), what is that?).

You can get bold names easily with the new name wrapper commands (added in biblatex v3.12 from 2018-10-30)
