Change Biblatex Citation Style After Preamble

Question

Is it possible to change the citation style after the preamble? My document requires "numeric" citation in the document, but then I would like to use "authoryear" as the headings for my appendices. Any ideas? MWE follows:

\listfiles
\documentclass{article}
\usepackage[backend=biber,style=numeric]{biblatex}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}

Some text \autocite{A01}.

\printbibliography
\clearpage

\appendix
\newpage
\vspace*{2in}
\begin{center}
\section{\Cite{A01}} % I want this to be the authoryear citation
\end{center}
\end{document}

Answer 1

Biblatex can't support multiple citation styles in the same document. However there are a variety of citation commands for printing specified fields from a given entry. For example:

\citeauthor{<key>}~\citeyear{<key>}

Here \citeauthor prints the labelname list for the entry <key>. The starred variant \citeauthor* truncates this list to the first name. \citeyear prints the year field. The starred variant \citeyear* appends year with extrayear to disambiguate multiple works having the same labelname and year. To access extrayear you need the labelyear option enabled:

\usepackage[style=numeric,labelyear]{biblatex}

Other entry fields can be cited via \citedate, \citetitle, \citeurl and the low-level citation commands:

\citename[<prenote>][<postnote>]{<key>}[<format>]{<name list>}
\citelist[<prenote>][<postnote>]{<key>}[<format>]{<literal list>}
\citefield[<prenote>][<postnote>]{<key>}[<format>]{<field>}

Note that these are specific to the data type (name list, literal list, field) of the entry field. Data types for all entry fields in the default data model can be found in the Entry Fields section of the biblatex manual's Database Guide. Further details on citation commands are provided in the Citation Commands section of the manual's User Guide.
