Here is a test document:

\documentclass[doc]{apa6}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa,sortcites=true,sorting=nyt,apabackref=true,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}

\printbibliography

\end{document}

I obtain this mess: Boker, S. et al., Neale, M. et al., Maes, H., et al., Wilde, M., et al., Spiegel, M., et al., Brick, T., et al., . . . Et al., et al., et al., Bates, T., et al. (2011). OpenMx: An open source extended structural equation modeling framework. Psychometrika, 76 (2), 306–317. (Cit. on p. 17).

I thought maybe I had a bad mix of versions. I tried "tlmgr update --all". I have biblatex 2.8 installed and I just installed biber 1.8 from http://biblatex-biber.sourceforge.net/. I still get too many "et al."

Suggestions?

  • Perhaps it is due to the mix or provide a long list of authors and then also adding and others. What happens if you get rid of the and others or provide the full list of authors? – jon Oct 30 '13 at 19:14
  • It seems to be connected to biblatex-apa: it does seem to do some weird things with the name list. One might add that getting rid of the and others string fixes the weird "et al"s appearing everywhere. – moewe Oct 30 '13 at 19:18
  • This has been corrected in biblatex-apa 6.4 which which has just been released. Thanks for spotting this. – PLK Oct 30 '13 at 21:36

This problem is due to biblatex-apa's (apa.bbx's) apaauthor name format; you might want to notify the author of this small bug.

The string and others in the author list sets ifmorenames to true. apaauthor checks for this case whenever a name is printed, not just at the very end of the list; consequently it prints the andothers string ("et al.") after each name.

The fix is to add the following lines to your preamble.

\DeclareNameFormat{apaauthor}{%
  \ifthenelse{\value{listcount}=\maxprtauth\AND\value{listcount}<\value{listtotal}}
    {\addcomma\addspace\ldots\addspace}
    {\ifthenelse{\value{listcount}>\maxprtauth\AND\value{listcount}<\value{listtotal}}
      {}
      {\ifthenelse{\iffieldequalstr{doubtfulauthor}{true}}
        {\mkbibbrackets{\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}?}}
        {\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}}}}%
  \ifthenelse{\value{listcount}=\value{listtotal}}% this test is new
    {\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{}}
