Bibliography style with bold name list (format entire list at once)

Question

Could you please suggest me which style should I use to get the bibliography in the style reported in the picture below?

The entire author/editor name lists is bold (including the "and", so it makes sense to format it as one unit), followed by the year of publication in parentheses.

Author/editor names should be given in the format last name, first initials, junior part, e.g.

Costa, P.T., Jr. and McCrae, R.R.

Answer 1

Using biblatex it should be possible to cook something up. Some aspects of the style may be more complicated to implement than others.

Although the desired style seems to share some elements with APA style (the name format) this answer does not build upon biblatex-apa. It can be quite complicated to apply even simple modifications to biblatex-apa, since the style has to do a lot to implement the complex requirements of the APA manual.

Instead I based the answer on ext-authoryear of my biblatex-ext style bundle, since the bundle offers a few shortcuts for some of the required modifications.

biblatex 3.12 introduced new name and list wrappers that allow you to easily typeset an entire name list in bold and not just parts of it (as is currently possible). This is what the

\DeclareNameWrapperFormat{sortname}{\mkbibbold{#1}}

does, see https://github.com/plk/biblatex/issues/754 and https://github.com/plk/biblatex/pull/829.

Other than that the most complicated redefinitions involves the name format, the rest is fairly straightforward (cf. Guidelines for customizing biblatex styles).
