[Tex/LaTex] Multilingual bibliographies with biblatex-chicago babel hyphenation

biberbiblatexlanguages

Don't know what I did (if I did anything) but seems multilingual libraries don't work for me anymore… I have some german and english references in an english document and so I want that english references are all output in small letters – for german titles, however, I want to keep the original spelling, including all capitals. Here's a minimal example:

\documentclass[10pt,oneside,a4paper]{scrartcl}

\usepackage[utf8]{inputenc}
\usepackage[usenames]{color} %used for font color
\usepackage{graphics}
\usepackage[british,german]{babel}
\usepackage{csquotes}
\setquotestyle{british}
\usepackage{mathdots}
\usepackage{amssymb} %maths
\usepackage{amsmath} %maths
\usepackage{authblk}
\setcounter{secnumdepth}{-1}

\clubpenalty=10000
\widowpenalty=10000
\displaywidowpenalty=10000


% ********************************BIBLATEX**************************
\usepackage[language=british,isbn=false,authordate,doi=false,babel=other]{biblatex-chicago}

\defbibheading{quell}{\section{Primary Ressources}}
\defbibheading{lit}{\section{References}}
% ******************************************************************

references would be, for example:

@book{aunger_darwinizing_2001,
title = {Darwinizing Culture: The Status of Memetics as a Science},
isbn = {0192632442},
language = {english},
hyphenation = {english},
pagetotal = {256},
publisher = {Oxford University Press},
editor = {Aunger, Robert},
date = {2001-01-04},
}

@book{rautenberg_einfuhrung_2008,
location = {Wiesbaden},
title = {Einführung in die mathematische Logik: ein Lehrbuch},
isbn = {9783834805782 3834805785},
shorttitle = {Einführung in die mathematische Logik},
hyphenation = {german},
publisher = {Vieweg + Teubner},
author = {Rautenberg, Wolfgang},
date = {2008},
}

but what happens is that all are

The Chicago Manual of Style no longer imposes sentence-style capitalization on titles. In response to this change the biblatex-chicago author moved sentence case title formatting from the default authordate style to a new style call authordate-trad. So to obtain an English bibliography with sentence-cased titles load babel and biblatex with the option settings:

\usepackage[german,british]{babel}
\usepackage[authordate-trad,babel=hyphen]{biblatex-chicago}

For a multilingual bibliography incorporating both English and German strings, change the setting babel=hyphen to babel=other. Note that you might need to protect some words in titles from down-casing. For example:

title = {Darwinizing Culture: {The} Status of Memetics as a Science},

Alternatively you can use the subtitle field:

title = {Darwinizing Culture},
subtitle = {The Status of Memetics as a Science},

Also note that sentence case is applied only under the language modules specified in \DeclareCaseLangs. By default:

\DeclareCaseLangs{%
  american,british,canadian,english,australian,newzealand,
  USenglish,UKenglish}

To include german in this list, add the following to your preamble:

\DeclareCaseLangs*{german}
