[Tex/LaTex] Formatting back references in bibliography [BibTeX]

babelback-referencingbibtexhyperref

I'm using the option pagebackref in hyperref package and I get just the links list at the end of each reference name. It should print something like "Cited on page/s ", but I don't manage it even to do that.

My aim is to change some command to make it say that in Spanish, and I found it already considers Spanish in backref.sty, which is called by hyperref, I think… Reading hyperref, backref, backrefx's documentation didn't help.

Any guess?

Use:

\usepackage[pagebackref=true]{hyperref}
\renewcommand*{\backref}[1]{}
\renewcommand*{\backrefalt}[4]{[{\tiny%
    \ifcase #1 Not cited.%
          \or Cited on page~#2.%
          \else Cited on pages #2.%
    \fi%
    }]}

I put this is in a \tiny font in between square brackets []. Change to your own tastes:)

[Tex/LaTex] Formatting back references in bibliography

Here's a solution using biblatex:

\documentclass{article}

\usepackage[backref=true]{biblatex}

\usepackage{hyperref}

\DefineBibliographyStrings{english}{%
  backrefpage = {page},% originally "cited on page"
  backrefpages = {pages},% originally "cited on pages"
}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
@misc{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

Some text \autocite{A01,B02}.

\clearpage

Some more text \autocite{A01}.

\printbibliography

\end{document}

enter image description here

And a brute-force solution for natbib/backref:

\documentclass{article}

\usepackage[numbers]{natbib}

\usepackage[backref=page]{hyperref}

\usepackage{etoolbox}
\makeatletter
\patchcmd{\BR@backref}{\newblock}{\newblock(page~}{}{}
\patchcmd{\BR@backref}{\par}{)\par}{}{}
\makeatother

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
@misc{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
\end{filecontents}

\begin{document}

Some text \citep{A01,B02}.

\clearpage

Some more text \citep{A01}.

\bibliographystyle{plainnat}
\bibliography{\jobname}

\end{document}

[Tex/LaTex] Precise back-reference target with hyperref and backref

There are essentially three parts to the patch.

Adding a \phantomsection before every \cite does most of the work. These phantom sections are what the hyperrefs point back to.
Convince backref to point the hyperlinks back to the phantom sections even if using page numbers as the labels.
Don't let backref over-rule our hyper-target (and use the start of the document instead) if it thinks there's no section to point back to.

The patch has now been updated to hopefully work as expected in all situations, either when using natbib or not. See the post history if not interested in natbib support. Note that biblatex provides its own backref mode, but does not provide direct links, and this patch does not work there (and should not be used!)

Patch code (use in document preamble after loading the hyperref package with a backref option; note this will fail ungracefully without hyperref!):

%%%% these patches ensure that the backrefs point to the actual occurrences of the citations in the text, not just the page or section in which they appeared
%%%% https://tex.stackexchange.com/questions/54541/precise-back-reference-target-with-hyperref-and-backref
%%%% BEGIN BACKREF DIRECT PATCH, apply these AFTER loading hyperref package with appropriate backref option
% The following options are provided for the patch, currently with a poor interface!
% * If there are multiple cites on the same (page|section) (depending on backref mode),
%   should we show only the first one or should we show them all?
\newif\ifbackrefshowonlyfirst
\backrefshowonlyfirstfalse
%\backrefshowonlyfirsttrue
%%%% end of options

%    * in case natbib is loaded. hyperref provides an appropriate hook so this should be safe, and we don't even need to check if natbib is loaded!
\let\BR@direct@old@hyper@natlinkstart\hyper@natlinkstart
\renewcommand*{\hyper@natlinkstart}{\phantomsection\BR@direct@old@hyper@natlinkstart}% note that the anchor will appear after any brackets at the start of the citation, but that's not really a big issue?
%    * if natbib isn't used, backref lets \@citex to \BR@citex during \AtBeginDocument
%      so just patch \BR@citex
\let\BR@direct@oldBR@citex\BR@citex
\renewcommand*{\BR@citex}{\phantomsection\BR@direct@oldBR@citex}%

% 2. if using page numbers, show the page number but still hyperlink to the phantomsection instead of just the page!
\long\def\hyper@page@BR@direct@ref#1#2#3{\hyperlink{#3}{#1}}

% check which package option the user loaded (pages (hyperpageref) or sections (hyperref)?)
\ifx\backrefxxx\hyper@page@backref
    % they wanted pages! make sure they get our re-definition
    \let\backrefxxx\hyper@page@BR@direct@ref
    \ifbackrefshowonlyfirst
        %\let\backrefxxxdupe\hyper@page@backref% test only the page number
        \newcommand*{\backrefxxxdupe}[3]{#1}% test only the page number
    \fi
\else
    \ifbackrefshowonlyfirst
        \newcommand*{\backrefxxxdupe}[3]{#2}% test only the section name
    \fi
\fi

% 3. now make sure that even if there is no numbered section, the hyperref's still work instead of going to the start of the document!
\RequirePackage{etoolbox}
\patchcmd{\Hy@backout}{Doc-Start}{\@currentHref}{}{\errmessage{I can't seem to patch backref}}
\makeatother
%%%% END BACKREF PATCHES

And all together in the context of an MWE (based on the provided one, but extended), and now using the biblio.bib example file which should hopefully get found automatically (otherwise use the link to get it from CTAN):

\begin{document}
Top of page. No sections at all here yet.
\vfill
\cite{GSM97}
\vfill
\cite{Lam94}
\section*{Unnumbered}
Check that things work in unnumbered sections.

\cite{Lam94}

\newpage
\section{Numbered}
And in numbered sections!

This is just a test \citep{GSM97} on another page and not at the start of the line to see how well things work.

And other citation to something already cited \cite{GSM97} on the same page in the same section.

\section{Another numbered one}
And another dupe test \citet{GSM97}.

\newpage
\bibliography{biblio}
\end{document}

Note that this example uses \citet and \citep from natbib just to check that they work as expected.
