I’m wondering why the Chicago Manual of Style output style has some of the extra information that it does. For example, the bibliography template for books looks like this:
Author. Title Prefix Title [in Language]| [Translated Title]|. Translated by Translator|. Series Title|. edited by Series Editor|. Edition ed. Number of Volumes vols|. Vol. Volume,| Place Published|: Publisher, Year|. Type of Work|.
doi:DOI|. Reprint Edition|. Original Publication|.
So I get a citations like these:
Sand, Jordan. Tokyo Vernacular : Common Spaces, Local Histories, Found Objects [in English]. Berkeley: University of California Press, 2013.
Fielitz, Sonja, and Hans Ulrich Gumbrecht. Präsenz Interdisziplinär : Kritik Und Entfaltung Einer Intuition [in German]. Beiträge Zur Neueren Literaturgeschichte,; Bd. 301; Variation: Beiträge Zur Neueren Literaturgeschichte ;; Bd. 301. Heidelberg: Winter, 2012. Conference publication (cnp).
(I exported these titles from WorldCat.)
As far as I can tell, the Chicago Style (16th ed.) doesn’t call for specifying language in brackets after the title or for indicating the type of work after the publication information. I could edit my copy of the output style, but I mention this because I think the current template (at least in some cases) is incorrect, and corrections could benefit the whole community if they went into the “master” output style.
