BibTeX, biblatex and biber ⇒ biblatex does not keep capital letters in Journal name

[Curran92]

Hi everyone,

I am new to LaTeX and I have an issue with the bibliography that I am writing using biblatex. The problem is that the journal names appear in the printed bibliography with just the first letter capitalized, for example I get "Materials research society bulletin" instead of "Materials Research Society Bulletin". I know that this is what should happen with the article titles (and in fact it happens), but how can I avoid this to happen also for the journal names?

Here is an excerpt of my main file:

Code: Select all

\documentclass[12pt,a4paper,titlepage]{memoir}
\usepackage[OT1]{fontenc}
\usepackage[french,english]{babel}
\usepackage[utf8]{inputenc}
\usepackage[linkcolor=black,colorlinks=true,citecolor=black,filecolor=black]{hyperref}
\usepackage[backend=bibtex,style=ieee]{biblatex}
\addbibresource{refs.bib}

\begin{document}
\backmatter
\printbibliography
\end{document}

and here is an example of one entry of my references file, refs.bib:

Code: Select all

@article{2014rogers,
  title={Materials for semiconductor devices that can bend, fold, twist and stretch},
  author={Rogers, J. A.},
  journal={Materials Research Society Bulletin},
  year={2014},
  number={},
  pages={549-556},
  volume={39},
  doi={10.1557/mrs.2014.102},
}

Thank you for your help!

I am still running an old version of TeX Live, and i can't reproduce the issue. With TeX Live 2016, according the the friendly people ich chat, the behaviour can be seen for english (which is normal for the english language), but not with german (where it is uncommon).

Thank you for your help.

However, I don't understand how to use the \DeclareCaseLangs{} command to fix my issue. I have tried to type it in the following way:

Code: Select all

\usepackage[backend=bibtex,style=ieee]{biblatex}
\DeclareCaseLangs{}
\addbibresource{refs.bib}

but it did not change anything.

Anyway, I have checked the biblatex-ieee package released by Joseph Wright on the 27th of June, and I see that the latest version (v1.1o) brought a change that "fixes the capitalization of journal titles". So I think this might be a solution to my issue; I'll try to update the package, compile again and let you know if something changes.

EDIT: updated the package, now journal names are capitalized in the correct way.

Thank you very much for your support.

Just in case it would not work: capitalization could be protected by enclosing the whole title in braces.
