[Tex/LaTex] babelbib styles format first and second author names differently

Question

I use babelbib and I have a source with two authors. Contrarily to when using the plain bib style, as soon as I switch to babplain, the author names are formatted like this:

[1] Müller, Jan und Eva Schulze: Name of the book, 2015.

While I would like both author names to be formatted the same way, that is one of these:

[1] Müller, Jan und Schulze, Eva: Name of the book, 2015.
[1] Jan Müller und Eva Schulze: Name of the book, 2015.

sources:

% test.tex
\usepackage[ngerman]{babel}
\usepackage[fixlanguage]{babelbib}
\selectbiblanguage{ngerman}
\bibliographystyle{babplain}
\bibliography{test}

% test.bib
@manual{foo,
    author = "Müller, Jan and Schulze, Eva",
    title = "Name of the book",
    year = "2015",
}

I can fix it by specifying and {Schulze, Eva}, but that way all is treated as the last name, that cannot be the solution, can it?

Answer 1

From the babelbib manual:

If you don’t want this behaviour you can use additional variants that use the same notation for all names. By appending -fl to the style name, e.g., babalpha-fl, all names are written “Forename Lastname”. By appending -lf, e.g., babalpha-lf, all names are written “Lastname, Forename”.

So use babplain-lf instead of babplain if you want

[1] Müller, Jan und Schulze, Eva: Name of the book, 2015.

or babplain-fl if you want

[1] Jan Müller und Eva Schulze: Name of the book, 2015.

Your example with babplain-lf:

\documentclass{article}

\usepackage[utf8]{inputenc}

\usepackage[ngerman]{babel}
\usepackage[fixlanguage]{babelbib}
\selectbiblanguage{ngerman}
\bibliographystyle{babplain-lf}

\begin{document}

\nocite{*}
\bibliography{test}

\end{document}
