The styles of the biblatex-chicago
package are a bit special in that it is recommended to load them via the special wrapper package biblatex-chicago
and not via biblatex
and its style
option.
Furthermore, in the question you only load biblatex-chicago
's authordate
style for citations, the bibliography is still in the standard authoryear
style. I can not recommend mixing non-biblatex-chicago
and biblatex-chicago
styles.
Since biblatex-chicago
is for the most part just a thin wrapper around biblatex
that sets relevant options, you should be able to do most things you can do with standard biblatex
also with biblatex-chicago
. (There is a small difference in the option handling of some options. For example, biblatex-chicago
's implementation of the natbib
compatibility option does not accept a value, but biblatex
's version does.)
I suggest you load biblatex-chicago
as
\usepackage[authordate,
backend=biber,
]{biblatex-chicago}
You can add additional options when you have verified that you need them.
\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[authordate,
backend=biber,
]{biblatex-chicago}
\addbibresource{biblatex-examples.bib}
\begin{document}
\autocite{sigfridsson,nussbaum}
\printbibliography
\end{document}

In the comments Paul Stanley mentions a more recent alternative to biblatex-chicago
: windycity
. There are small differences in the output between the two packages, but the general feeling is the same.
biblatex-chicago
's authordate
style corresponds to windycity
's reflist
option.
\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[style=windycity,
reflist,
autocite=inline,
backend=biber,
]{biblatex}
\addbibresource{biblatex-examples.bib}
\begin{document}
\autocite{sigfridsson,nussbaum}
\printbibliography
\end{document}

chicago-authordate
but toauthoryear
... I get an error about conflicting options with this anyway ... I also think you are confused about the waybiblatex-chicago
works: it is a biblatex format, albeit a slightly special one: and in fact I think you are loading it, albeit not in the special way it prefers. An alternative chicago style, more recently developed iswindy-city
.biblatex-chicago
should usually be called with its wrapper package\usepackage[authordate]{biblatex-chicago}
instead of\usepackage[style=chicago-authordate]{biblatex}
. Note further thatstyle=authoryear, citestyle=chicago-authordate,
means that you are essentially not using Chicago style at all. I am also not sure if using a non-Chicago bibliography style with a Chicago citation style is supported. It should be possible to get split bibliographies and similar things also withbiblatex-chicago
and its wrapper package.style=chicago-authordate
solves the whole problem. I might keep it like that or try calling it with\usepackage[authordate]{biblatex-chicago}
. In any case, thank you!
