[Tex/LaTex] customized \footcite command

biblatexcitingfootnotes

Based on an answer on new line for doi eprint url in the bibliography with biblatex, a question arose on the possible use of the \footcite command with the provided new style. This \footcite command seems to be a good compromise for rather long scripts where you do not want to disturb the main text with things like [Author Year] (authoryear style) or when you want to provide more information than [1] (numeric style). So, the question is how to create a personal biblatex style based on the numeric style that would provide information in a footnote when \footcite is used. Minimal information here should be thought for each case @article, @book, @phdthesis, @inproceedings but would just indicate contracted author names, title, year… The link to the main reference in the bibliography section should be added as well in the footnote.

Best Answer

You can define a new citation command based on \footcite under the numeric style and the generic citation commands \citeauthor, \citetitle and \citeyear. How all the entry information is ordered and delimited is up to you. Here's an example.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{csquotes}
\usepackage[american]{babel}
\usepackage[colorlinks]{hyperref}
\usepackage[style=numeric]{biblatex}

% Adapted from \footcite in numeric.cbx and generic citation
% commands \citeauthor, \citetitle, \citeyear in biblatex.def
\DeclareCiteCommand{\footpartcite}[\mkbibfootnote]
  {\usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \mkbibbrackets{\usebibmacro{cite}}%
   \setunit{\addnbspace}
   \printnames{labelname}%
   \setunit{\labelnamepunct}
   \printfield[citetitle]{title}%
   \newunit
   \printfield{year}}
  {\addsemicolon\space}
  {\usebibmacro{postnote}}

\DeclareMultiCiteCommand{\footpartcites}[\mkbibfootnote]{\footpartcite}{\addsemicolon\space}

\addbibresource{biblatex-examples.bib}

\begin{document}
\null\vfill\noindent
Filler text.\footpartcite{bertram}
Filler text.\footpartcites(See)(for example){markey}[10--15]{companion}
\printbibliography
\end{document}

[Tex/LaTex] Problem Footcite Biblatex

If the first name is displayed with style=authoryear and \footcite, you're doing something wrong -- my guess is an additional set of braces around the author in your .bib file.

The formatting of the footnote has nothing to do with biblatex. You may use, e.g., the scrextend package (part of KOMA-Script) to get a space between footnote mark and text.

EDIT: Added solution for "semicolon after title of articles".

EDIT 2: It seems you need semicolons after every "unit". Try to remove the redefinition of the in: bibmacro and add instead \renewcommand*{\newunitpunct}{\addsemicolon\space}.

\documentclass{article}

\usepackage{scrextend}
\deffootnote{1.5em}{1em}{\textsuperscript{\thefootnotemark}~}

\usepackage[style=authoryear,autocite=footnote]{biblatex}

\renewbibmacro*{cite:labelyear+extrayear}{%

   \printtext[parens]{% <- space
   \printfield{labelyear}%
   \printfield{extrayear}}}}}

\renewbibmacro{in:}{%
  \ifentrytype{article}{%

    \printtext{\bibstring{in}\intitlepunct}%

}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@article{A01,
  author = {Author, A.},
  year = {2001},

  journaltitle = {A Journal},
  volume = {1},
  number = {1},
}
@misc{B02,
  author = {{Buthor, B.}},% Too many braces!

[Tex/LaTex] Citing author inline and year in footnote using biblatex

Second solution

Edited again, so most multicite commands work.

Edited so \footcite now works.

A reasonably effective solution that preserves many of biblatex's featuers is provided by adjusting the way the year gets printed in citations. This can be done by redifining the commands associated to cite:year and cite:extrayear. This has the advantage of preserving the ibidem feature.

The code below includes a sample bibliography and then the main file with the redefined citation code.

\begin{filecontents}{test.bib}
@Article{Test,
author = {Author, A. N.},
title = {Article title},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
@Article{Test2,
author = {Author, A. N.},
title = {Second article},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
@Article{Test3,
author = {Author, A. B.},
title = {Third article},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
@Article{Test4,
author = {Author, A. N.},
title = {Fourth article},
year = 2007,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
\end{filecontents}

\documentclass{article}
\usepackage[style=authoryear-icomp,autocite=plain]{biblatex}

\addbibresource{test.bib}

\renewbibmacro*{cite:labelyear+extrayear}{%
  \iffieldundef{labelyear}
    {}
    {\iftoggle{blx@footnote}
      {\printtext[bibhyperref]{%
       \printfield{labelyear}%
       \printfield{extrayear}}}
      {\footnote{\printtext[bibhyperref]{%
       \printfield{labelyear}%
       \printfield{extrayear}}}}}}

\renewbibmacro*{cite:extrayear}{%
  \iffieldundef{extrayear}
    {}
    {\iftoggle{blx@footnote}
      {\printtext[bibhyperref]{\printfield{extrayear}}}%
      {\footnote{\printtext[bibhyperref]{%
      \printfield{labelyear}%
      \printfield{extrayear}}}}}}

\renewcommand{\compcitedelim}{\space}

\begin{document}
\thispagestyle{empty}
\autocite{Test} and
\autocite[page 3]{Test}.
Some text \parencite{Test2}.

Here is a footnote citation\footcite{Test}.

\autocite{Test,Test4,Test3}.

\printbibliography
\end{document}

Sample output

As the above shows this works with \autocite, \parencite and accepts their optional arguments. In this style \autocite is the same as \cite.

I haven't demonstrated \textcite, though its ouptut may be useful sometimes; \footcite has also been set up to work, thanks to biblatex's blx@footnote toggle that detects whether we are in a footnote or not.

The code also takes care of most multiple citations \cite{ref1,ref2}. However, there is a spurious comma, if ref1 and ref2 are two publications from the same author in the same year. Fixing that requires, more substanitial rewriting of the citation style file: each of the commands \cite, \textcite, etc. in author-icomp.cbx contains an explicit comma via \setunit{\addcomma}, that needs to be deleted.

Original solution

Here is a repost of the original solution, as this apparently helps the OP best. It simply defines a newcommand \citepfy (plain-foot-year) that calls \citeauthor followed by a modified \footcite command that produces only the year. It does not accept any of the optional arguments cite commands in biblatex usually do.

\begin{filecontents}{b.bib}
@Article{Test,
author = {Author, A. N.},
title = {Article title},
year = 2005,
pages = {10-20},
journal = {Jour.},
vol = {100}
}
\end{filecontents}

\documentclass{article}
\usepackage[style=authoryear-icomp]{biblatex}

\addbibresource{b.bib}

\newcommand{\citepfy}[1]{\citeauthor{#1}\footyearcite{#1}}
\DeclareCiteCommand{\footyearcite}[\mkbibfootnote]
  {\usebibmacro{cite:init}%
   \usebibmacro{prenote}}
  {\usebibmacro{citeindex}%
   \usebibmacro{citeyear}}
  {}
  {\usebibmacro{cite:postnote}}
