Does anyone have an idea as to why my bibliography is rendered in this way (see image)? This happens to all @article entries.

Strange Quote Behavior

The .bib entry is

author={Lecun, Y. and Bottou, L. and Bengio, Y. and Haffner, P.},
journal={Proceedings of the IEEE},
title={Gradient-based learning applied to document recognition},

I am using cleanthesis.sty with the defaults (bibtex), editing with Texmaker on Windows.

    It is because you, some package you are loading, or cleanthesis.sty (not cleanthesis.cls?) is likely loading a language module like german for either babel or polyglossia.

  • Welcome to TeX.SX! Can you be a bit more precise about what you object to in the output. I can't see a broken quotation mark. (They are not your standard English/American quotation marks though, they look like the ones used in German amongst other languages.) What I think a bit meh is the space between the label and the entry which is almost non-existent. But to change that we would need to know more about your document, to that end a MWE would be extremely helpful.

  • Yes, you are both correct, it was loading csquotes with german. Thanks to both of you! Sep 21, 2015 at 8:28

The solution is to remove the german-style quotes option.

In cleanthesis.sty

\RequirePackage[                    % advanced quotes
    strict=true,                    %   - warning are errors now
    style=german                    %   - german quotes


\RequirePackage[                    % advanced quotes
    strict=true,                    %   - warning are errors now
    style=english                   %   - english quotes
  • I'd rather say that the solution would be avoiding such a rigid style or, at least, asking its author to fix the language dependences of the style.
