BibTeX, biblatex and biber ⇒ Extra blank page before References when the last page is full - APA6 A4 template, Xetex

[ocoolio]

I badly need your expert help, tried to find solutions to no avail.

In a simple document when the last line of the last page is full, LaTeX will render a blank page before inserting the references. If the last page is not full, there is no blank page.

I think I haven't used anything special so I have no idea what this is and how to fix it.

Help please!

Welcome to the forum!

A quick solution would be adding heading=bibnumbered:

Code: Select all

\printbibliography[heading=bibnumbered]

hey Stefan, thanks heaps for such a quick response!

Your solution is almost perfect but it changes the "Refereces" heading to bold and that is not APA compliant.

Any other suggestions perhaps?

Thanks!

EDIT: meanwhile, it seems I got the perfect response on the Stackexchange forum, in case someone finds this thread.

That's easy to change too. Anyway, I guess that's the best (of moewe):

Code: Select all

\AtEndPreamble{%
  \defbibheading{bibliography}{\clearpage\section*{\normalfont\refname}}%
}

Or, after \begin{document} but before the bibliography

Code: Select all

\defbibheading{bibliography}{\clearpage\section*{\normalfont\refname}}%

Especially because \clearpage forces printing the remaining figures and tables before the bibliography starts. That's desirable.

Can you please explain the difference between the AtEndPreamble and the other approach? I think it's a noob question but I'm really interested
Thanks again Stefan!

[Stefan Kottwitz]

\AtEndPreamble is hook command for executing code right at the end of the preamble, so one can override document class definitions. But I think it's from the etoolbox package, so it's required to load etoolbox. The other quick approach is simply placing that definition yourself. I guess apa6.cls already loads etoolbox implicitly, my remark was for the case it won't or it's not installed or another reader stumbles across it later.
