[Tex/LaTex] way to prevent URLs from appearing in \bibentry citations

bibliographiesbibtexnatbibtufte

I'm using Tufte document classes, in which citations appear as sidenotes consisting of the full bibliography entry, using (I believe) \bibentry. Many of my bibliography entries contain URLs (and I want them there) but I don't want those URLs to appear in the citations.

Is there a way to omit URLs from such citations but keep them in the bibliography?

Example of citation with unwanted URL

\documentclass[]{tufte-handout}

\begin{document}

This,\cite{Sarukkai:2005} includes the URL for the citation, which I don't want; thought I do want it in the bibliography.

\bibliographystyle{unsrtnat}
\bibliography{References}

\end{document}

@article{Sarukkai:2005,
author = {Sarukkai, S},
title = {{Revisiting the 'unreasonable effectiveness' of mathematics}},
journal = {Current science},
year = {2005},
url = {http://www.ias.ac.in/currsci/feb102005/415.pdf},
}

This is possible by modifying the bst-file.

Copy the file unsrtnat.bst in your working folder. I recommand to rename the file maybe something like MYunsrtnat.bst. At line 285 of MYunsrtnat.bst you find the definition of the url output.

FUNCTION {format.url}
{ url empty$
    { "" }
    { new.block "URL \url{" url * "}" * }
  if$
}

Change this definition as follow:

FUNCTION {format.url}
{ url empty$
    { "" }
    { new.block "\urlname{URL} \url{" url * "}" * }
  if$
}

After this changing you can use the following example. There commands \urlname and \url gobble their argument. Before the bibliography is printed to commands are set to

\renewcommand*{\urlname}[1]{#1}
\renewcommand*{\url}[1]{\texttt{#1}}

Here the example:

\documentclass[]{tufte-handout}
\usepackage{filecontents}
\begin{filecontents}{References.bib}
@article{Sarukkai:2005,
author = {Sarukkai, S},
title = {{Revisiting the 'unreasonable effectiveness' of mathematics}},
journal = {Current science},
year = {2005},
url = {http://www.ias.ac.in/currsci/feb102005/415.pdf},
}


\end{filecontents}
\providecommand*{\urlname}[1]{}
\renewcommand*{\url}[1]{}
\begin{document}
This,\cite{Sarukkai:2005} includes the URL for the citation, which I don't want; thought I do want it in the bibliography.

\renewcommand*{\urlname}[1]{#1}
\renewcommand*{\url}[1]{\texttt{#1}}
\bibliographystyle{unsrtnat}
\bibliography{References}

\end{document}

[Tex/LaTex] automatically generate abbreviated citations in Tufte documents after the first occurrence

Add the following code to the preamble of your document:

\usepackage{etoolbox}% provides some support for comma-separated lists

\makeatletter
% We'll keep track of the old/seen bibkeys here.
\def\@tufte@old@bibkeys{}

% This macro prints the full citation if it's the first time it's been used
% and a shorter citation if it's been used before.
\newcommand{\@tufte@print@margin@citation}[1]{%
  % print full citation if bibkey is not in the old bibkeys list
  \ifinlist{#1}{\@tufte@old@bibkeys}{%
    \citealp{#1}% print short entry
  }{%
    \bibentry{#1}% print full entry
  }%
  % add bibkey to the old bibkeys list
  \listgadd{\@tufte@old@bibkeys}{#1}%
}

% We've modified this Tufte-LaTeX macro to call \@tufte@print@margin@citation
% instead of \bibentry.
\renewcommand{\@tufte@normal@cite}[2][0pt]{%
  % Snag the last bibentry in the list for later comparison
  \let\@temp@last@bibkey\@empty%
  \@for\@temp@bibkey:=#2\do{\let\@temp@last@bibkey\@temp@bibkey}%
  \sidenote[][#1]{%
    % Loop through all the bibentries, separating them with semicolons and spaces
    \normalsize\normalfont\@tufte@citation@font%
    \setcounter{@tufte@num@bibkeys}{0}%
    \@for\@temp@bibkeyx:=#2\do{%
      \ifthenelse{\equal{\@temp@last@bibkey}{\@temp@bibkeyx}}{%
        \ifthenelse{\equal{\value{@tufte@num@bibkeys}}{0}}{}{and\ }%
        \@tufte@trim@spaces\@temp@bibkeyx% trim spaces around bibkey
        \@tufte@print@margin@citation{\@temp@bibkeyx}%
      }{%
        \@tufte@trim@spaces\@temp@bibkeyx% trim spaces around bibkey
        \@tufte@print@margin@citation{\@temp@bibkeyx};\space
      }%
      \stepcounter{@tufte@num@bibkeys}%
    }%
  }%
}


% Calling this macro will reset the list of remembered citations. This is
% useful if you want to revert to full citations at the beginning of each
% chapter.
\newcommand{\resetcitations}{%
  \gdef\@tufte@old@bibkeys{}%
}
\makeatother

It keeps a list of known/old/seen bibkeys. Each time you call \cite{key}, it will add those bibkeys to the list. When it prints the reference in the margin, it will check the list of known keys. If we've seen the key before, we'll call \citealp{key}. If we haven't seen the key before, we'll call the usual \bibentry{key}.

I've thrown in a \resetcitations macro (for free!) that will cause LaTeX to forget all the bibkeys it's seen before. This can be used, for instance, at the beginning of each chapter so that you'll see the full reference for the first citation of each chapter.

Note that this macro isn't particularly efficient. It doesn't sort the list of known bibkeys and checking the list is a linear-time process, so it will take longer the more \cites you have.

[Tex/LaTex] IEEEtran BibTeX Style – how to deactivate URLs

If you don't want BibTeX to print out the URL field for a given entry even though a URL field is present, you need to edit the bibliography style file -- in the present case, the file IEEEtran.bst -- to disable this printing. Make a copy of the file IEEEtran.bst and call it, say, myIEEEtran.bst. Open the new file in a text editor and search for the function format.url. It should look like this:

FUNCTION {format.url}
{ url empty$
    { "" }
    { this.to.prev.status
      this.status.std
      cap.yes 'status.cap :=
      name.url.prefix " " *
      "\url{" * url * "}" *
      punct.no 'this.status.punct :=
      punct.period 'prev.status.punct :=
      space.normal 'this.status.space :=
      space.normal 'prev.status.space :=
      quote.no 'this.status.quote :=
    }
  if$
}

Replace this function with the following "dummy" function:

FUNCTION {format.url}
{ url empty$
    { "" }
    { "" }
  if$
}

In short, you're telling BibTeX not to print out any information contained in the URL field. Save the file, update the filename database if necessary (e.g., if using TeXLive, type texhash in a command window), and be sure to use the new bibliography style file from now on. Happy TeXing!
