[Tex/LaTex] Editing the bibliography without changing citations in the text

biblatexline-breakingpage-breaking

Preparing my manuscript for publication, I need to manually redact the bibliography I generated with biblatex (style authortitle-dw) and Biber. This is mostly about fixing the line and page breaks (some nasty URLs, making sure that bib items do not break across pages, etc., see pictures below). I cannot make these fixes in the *.bbl file since the changes there would also affect the citations in the text. Any ideas how to do that?

Bad URL (too long)

Best Answer

To make sure that bibliography items do not break across pages, change the definition of \bibsetup so that \interlinepenalty is set to 10000 instead of 5000.

\patchcmd{\bibsetup}{\interlinepenalty=5000}{\interlinepenalty=10000}{}{}

Here's the original definition from biblatex.def:

\newcommand*{\bibsetup}{%
  \interlinepenalty=5000\relax
  \widowpenalty=10000\relax
  \clubpenalty=10000\relax
  \raggedbottom
  \frenchspacing
  \biburlsetup}

[Tex/LaTex] Manually breaking a long URL (in the bibliography)

Update: This question's OP himself has found a good solution between an extra \\ and a working hyperref.

With the help of the hyperref package one can write (the example is changed to an unpublished publication because there is, apparently, no journal):

@unpublished{koepke2009naturalness,
  year={2009},
  title={Naturalness in formal mathematics},
  note={\\
        \href{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             {\nolinkurl{http://www.math.uni-bonn.de/people/}}
        \\
        \href{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             {\nolinkurl{koepke/Preprints/Naturalness_in_formal_mathematics.pdf}}
       },
  author={Koepke, Peter}
}

which gives
$Output with two \hrefs$

If only one \href is used, like

  note={\\
        \href{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             {\nolinkurl{http://www.math.uni-bonn.de/people/}
             \\
              \nolinkurl{koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             }
       },

the link-active area spans the whole first line: $Output with one \href$

Original answer

An underfull hbox doesn't mean that there's necessarily something wrong. It is merely a warning.

Compare the bibliography entries of the following code.
The one with the extra \\ doesn't give a warning (but breaks the hyperlink, by the way), the other one does give a warning, but looks the same.

(The italic setting from the journal field did mess up the spacing either way.)

Code

\documentclass[natbib]{svmono}
\usepackage{url}
\usepackage[showframe,pass]{geometry}
\begin{filecontents}{test.bib}
@article{koepke2009naturalness,
  year={2009},
  title={Naturalness in formal mathematics},
  journal={Same Journal Name},
  note={\\\url{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_}\\\url{formal_mathematics.pdf}},
  author={Koepke, Peter}
}
@article{koepke2009naturalnessa,

[Tex/LaTex] One \cite crash all

Short answer: A hyphen in one of the bibliography entries gives an encoding error. To solve this, delete the letter and retype it.

How to find the one \cite to crash them all!!!

Make a copy or another form of backup of your project.
Find out which bibliography entry causes the problem by step by step removing the other ones or the cites in your .tex file [I find it easier to see if the error is gone, if I delete all the .log files between compilations, because otherwise it can survive there for a few compilations]
Find out which field is causing the error. Since Biblatex thankfully is very tolerant about missing fields, just remove field by field until the error is gone.
On could probably just have looked up the unicode number of the error message, but from experience - are prone to be some bad characters, so it was just a lucky guess. Other examples of characters prone to be in disguise are spaces, ligatures (such as ﬁ), accented letters or math symbols.
