[Tex/LaTex] Multiple citations styles in the body text (biblatex), based on keywords

biblatexcitingkeywords

I've been looking for a while, but I don't manage to use multiple citation styles with biblatex, depending on different keywords contained in the .bib file.

I already use keywords to sort my bibliography, using \printbibliography[keyword=primary] and \printbibliography[notkeyword=primary].

I would like, the same way, to differentiate primary and secondary sources in the text of my thesis. My goal is to use only \autocite in the body text. Depending on the keyword of the reference (=primary or not), I'd like my primary sources to automatically appear in footnotes (precisely using \footfullcite), and my secondary sources to appear in traditional authoryear style in the body text.

Is there a way to define it so in the preamble? Maybe using categories?

Very short answer: this is simply not possible at the moment. biblatex doesn't support multiple styles in one document. biblatex 2.0 which is due soon will support multiple sorting schemes, but that's it for the moment.

Maybe a feature request is in order here.

[Tex/LaTex] biblatex: multiple bibliographies categorised by different .bib files

This is now implemented in Biber 0.9.8. Here is how to deal with your question. Given the sample file:

\begin{filecontents}{\jobname-primary.bib}
@BOOK{hectic,
  AUTHOR    = {Henry Hectic},
  TITLE     = {How Horticulturalists Howl},
  PUBLISHER = {Honorary Books: Henage},
  YEAR      = {2000}
}
\end{filecontents}
\begin{filecontents}{\jobname-secondary.bib}
@BOOK{flutter,
  AUTHOR    = {Frederick Flutter},
  TITLE     = {Fraternising with Flowers},
  PUBLISHER = {Frippery Pamphlets: Folkestone},
  YEAR      = {1995}
}
\end{filecontents}
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[backend=biber,style=authoryear]{biblatex}
\usepackage{csquotes}
\addbibresource{\jobname-primary.bib}
\addbibresource{\jobname-secondary.bib}

\begin{document}
Some citations: \cite{hectic}, \cite{flutter}.
\printbibliography[title=Primary Sources, keyword=primary]
\printbibliography[title=Secondary Sources, keyword=secondary]
\end{document}

You can automatically add the correct keywords to your data as Biber reads it by using the following biber.conf file:

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <sourcemap>
    <maps datatype="bibtex" bmap_overwrite="1">
      <map>
        <per_datasource>test-primary.bib</per_datasource>
        <map_step map_field_set="KEYWORDS" map_field_value="primary"/>
      </map>
      <map>
        <per_datasource>test-secondary.bib</per_datasource>
        <map_step map_field_set="KEYWORDS" map_field_value="secondary"/>
      </map>
    </maps>
  </sourcemap>
</config>

This will add the necessary keywords based on the datasource names. If you already had a KEYWORD field in your datasources which you wanted to keep, you could use the match/replace functionality instead:

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <sourcemap>
    <maps datatype="bibtex" map_overwrite="1">
      <map>
        <per_datasource>test-primary.bib</per_datasource>
        <map_step map_field_source="KEYWORDS" map_match="^" map_replace="primary,"/>
      </map>
      <map>
        <per_datasource>test-secondary.bib</per_datasource>
        <map_step map_field_source="KEYWORDS" map_match="^" map_replace="secondary,"/>
      </map>
    </maps>
  </sourcemap>
</config>

The Biber manual has been updated in 0.9.8 with documentation of the config file format and has more examples. The format of the user config file is a major change from 0.9.6 (and some changes also from 0.9.7) as the older format was a bit of a mess and couldn't be extended to cope with situations like this due to inherent limitations of the format itself. I opted for a real XML format for flexibility. You can also validate your config file now by passing the --validate_config option to Biber.

EDIT: Since biber 1.3, you there is an "append" mode for setting values in sourcemaps so it's easier like this, which deals with entries with or without an existing KEYWORDS field when you want to keep any existing values:

<?xml version="1.0" encoding="UTF-8"?>
<config>
  <sourcemap>
    <maps datatype="bibtex" bmap_overwrite="1">
      <map>
        <per_datasource>test-primary.bib</per_datasource>
        <map_step map_field_set="KEYWORDS" map_field_value="primary" map_append="1"/>
      </map>
      <map>
        <per_datasource>test-secondary.bib</per_datasource>
        <map_step map_field_set="KEYWORDS" map_field_value="secondary" map_append="1"/>
      </map>
    </maps>
  </sourcemap>
</config>

Here is the same thing using the biblatex macro interface which you can put directly in your document:

\DeclareSourcemap{
  \maps[datatype=bibtex, overwrite]{
    \map{
      \perdatasource{test-primary.bib}
      \step[fieldset=KEYWORDS, fieldvalue=primary, append]
    }
    \map{
      \perdatasource{test-secondary.bib}
      \step[fieldset=KEYWORDS, fieldvalue=secondary, append]
    }
  }
}

[Tex/LaTex] Define a bibliography environment

As I wrote in the comment it's not possible to use a bibenvironment for your purpose, since bibenvironments are ment to format the bibliography list.

Also biblatex doesn't provide an implemented solution to mix different bibliography styles (as far as I know), so you have to try to find a way on your own to achieve what you want.

My solution:

Choose a default bibliography style (authoryear in your case)
Create drivers and macros which will differ from the default bibliography style (bibdriver for article and author-macro in your case)
Create and implement a toggle, with which you can switch between the default bibliography style and your new macros.

This solution will (adapted) also work for more than 2 bibliography styles.

However, the weak point is, you have to take care of every difference to your default bibliography style – and in the case you want to change your default bibliography style you have to start over...

Here is your updated and commented MWE. I've deleted a lot of unnecessary (for our issue) macros / packages. It should show you the idea of my solution.

In addition to the MWE you may modify the new macros and also set up a sorting option in the \printbibliography command etc.
