[Tex/LaTex] Direct citations inside of footnotes

citingfootnotes

Consider a document in which footnotes are shown as a bibliography items in the citation list. Furthermore, there are footnotes which contain citations. For example

\footnote{See also \cite{citation}.}

shows up as

Bibliography
[1] See also [2].
[2] citation, Journal Name, *Journal number*.

Here comes the question: Is it possible to directly insert the citation in the footnote, i. e. with a command like

\footnote{See also \directcite{citation}.}

so that it reads

Bibliography
[1] See also citation, Journal Name, *Journal number*.

without copy-pasting the bibliography text and style manually into the footnote?

Minimal working example:

CITE.TEX

\documentclass[ a4paper, 10pt, notitlepage, aps, pra ]{revtex4-1} 
\RequirePackage[utf8x]{inputenc}
\bibliographystyle{apsrev4-1}
\begin{document}
This is a text with a Footnote \footnote{Also see \cite{book}.}.
\bibliography{CITE.bib}
\end{document}

CITE.BIB

@book{book,
author  = "Joe Cool",
title   = "How to make good citations" }

I must preface my answer by saying I did a solution in the article class rather than the class you gave (because my antique system couldn't conveniently download the new packages). Hopefully, these results still apply.

Perhaps you could get what you want with either the optional argument to \cite or else the \nocite command.

junk.tex

\documentclass{article}
\bibliographystyle{unsrt}
\begin{document}

This is a text with a Footnote \footnote{Also see \cite[Joe Cool,
\textit{How to make a good citation}]{bk1}.}.  For the default document
class, the use of the optional argument may not be to your liking.
However, I didn't (couldn't) try it for revtex4.1 class.

Alternately, you might try this\footnote{Also see \nocite{bk2} citation
Sam Cool, \textit{What He Said}.}

In both these cases, BibTeX doesn't put the cite material in the
footnote, you do.  However, since you know the cite material, it won't
be prone to screw-ups if your references get renumbered.
\bibliography{junk}
\end{document}

and junk.bib

@book{bk1,
author  = "Joe Cool",
title   = "How to make good citations" }

@book{bk2,
author  = "Sam Cool",
title   = "What He Said" }

And here is the result

For future reference, here is another solution that allows you to overwrite the default setting for the citations with an automatic "See:" prenote.

As discussed with lockstep, this functionality is not absolutely needed as an answer to the OP's question, but since \citelitand \cite have a semantic meaning in this case (i.e. direct and indirect citation), it may be relevant to have commands that reflect it. Furthermore, this solution is more customisable than a \newcommand, and could be used by other people who want to achieve a similar result.

Here is what you can write in the preamble:

% Create a cite command that uses the default autocite=footnote behaviour
\DeclareCiteCommand{\seecite}[\iffootnote\mkbibparens\mkbibfootnote]
    {% Replace \usebibmacro{prenote} by its demfinition and modify it
    \iffieldundef{prenote}
        {\bibstring{see}\addcolon%
        \setunit{\prenotedelim}}%
        {\printfield{prenote}%
        \setunit{\prenotedelim}}%
    }
    {\usebibmacro{citeindex}%
    \usebibmacro{cite}}
    {\multicitedelim}
    {\usebibmacro{postnote}}

As suggested in the original question, we use \citelit and \cite:

\let\citelit\autocite
\let\cite\seecite

Now, we can write this in the document:

\cite[92]{wayne12a}
\cite[Contra\addcolon][73]{joker10b}
\citelit[127]{joker10b}

Output for the above code

[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.
