BibTeX, biblatex and biber ⇒ Wrong break in Bibliography

[antonio314159]

Hi everyone.

I am writing my master thesis using overleaf. My problem is in the bibliography section since some entries are causing overfull \hbox. Do you know how to fix this?

I am using biblatex with these specifications:

\usepackage{hyperref}
\hypersetup{colorlinks,citecolor={black},urlcolor={black}}

\usepackage{csquotes}
\PassOptionsToPackage{
natbib=true,
style=authoryear-comp,
hyperref=true,
backend=biber,
giveninits=true,
uniquename=init,
maxcitenames=2,
parentracker=true,
url=true,
doi=true,
isbn=true,
eprint=true,
backref=true,
} {biblatex}
\usepackage{biblatex}
\DeclareNameAlias{sortname}{family-given}



% mit "month" and "language" from Bibliography
\AtEveryBibitem{%
\clearfield{month}{}%
\clearlist{language}{}%
}

% some natbib backwards compatibility
\let\citealp\cite
\let\cite\textcite

% increase vertical space between bibliography items.
\setlength\bibitemsep{0.5ex}
\setlength\bibnamesep{1.2ex}

% Comma before and after journal volume. Thanks to lockstep.
\renewbibmacro*{volume+number+eid}{%
\setunit*{\addcomma\space}% NEW
\printfield{volume}%
\printfield{number}%
\printfield{eid}}
\DeclareFieldFormat[article]{number}{(#1)}% number of a journal

% Citation Hyperlinks (not just years), thanks to Audrey.

The source code is more pleasant to read, if you use the BBCode for code blocks.

Somewhere in your bibliography there is at least one entry where the line break does not work and the content towers over the margin.

Try to create a minimal as possible example that shows the entry or entries in the bibliography.

Hello! Thanks for your answer and sorry for the code!

This is one of my entries in my .bib file where the text goes beyond the margins.

Code: Select all

@article{Kazemi_2015, 
    title={Modeling downstream petroleum supply chain: The importance of multi-mode transportation to strategic planning}, 
    volume={83},
    url={http://dx.doi.org/10.1016/j.tre.2015.09.004},
    DOI={10.1016/j.tre.2015.09.004},
    journal={Transportation Research Part E: Logistics and Transportation Review},

    }

Without a minimal working example you can only guess. If the word petroleum causes the problem, you can use the commands \hyphenation, \babelhyphenation (babel) or \DefineHyphenationExceptions (biblatex) to specify the hyphenation in the preamble yourself.

The hyphenated compound word multi-mode is unlikely to be the cause because of its central position in the line. On the other hand, such words are a possible cause of problems and should therefore be treated with babel shorthands.
