biblatex-apa and \fullcite* --> year of ambiguous citation

Question

I writing my PhD thesis with LaTeX using biblatex-apa as bib style.

Besides the bibliography, a section will present a list of my publications during PhD. I do this using the \fullcite commands in a simple list environment.

I have some publications, where the authors and the year of publication are the same. Biblatex sets them like it would do in the bibliography:

• Author1, Author2, & Author3 (2011a). TitleA. JournalA, ...
• Author1, Author2, & Author3 (2011b). TitleB. JournalB, ...

I would like to omit the letters in the year statement (but only for the \fullcite items in my publications section, not generally, i.e. affecting the bibliography)

Is that possible?

Answer 1

You have to add a \clearfield{extrayear} to your \fullcite command. You can to that by redefining it, or by creating your own command.

This MWE redefines the existing \fullcite:

^{I have tried, without success, to patch the command (via xpatch) instead of copying it and adding the \clearfield{extrayear}; perhaps this would be the best solution, but unfortunately, I couldn't do it.}

\documentclass{article}
\begin{filecontents}{\jobname.bib}
  @book{a,
    author = {A. Uthor},
    title = {A title},
    year = {2013}
  }
  @book{b,
    author = {A. Uthor},
    title = {Another title},
    year = {2013}
  }

  @article{c,
    author = {A. Uthor},
    title = {Another title from the same year},
    journal = {Journal},
    date = {2013-09}
  }
\end{filecontents}
