BibTeX, biblatex and biber ⇒ Problem with natbib/longnamesfirst option

[blackvoid]

Hi there,
I found on various websites that using the longnamesfirst option with the natbib package should print out full author lists for the first time a paper is cited. However, all citations (i.e. also the first) are still coming out as in the format "Smith et al., 1993" (rather than "Smith, Jones, and Miller, 1993"). I'm using texshop on a Mac and would be very grateful for any hints on what to do. Thanks!

I'm using the following:

Code: Select all

\usepackage[round,longnamesfirst]{natbib}
...
\bibliographystyle{apa}
\bibliography{mybibliography}

I just figured out what was wrong, so for future reference:
the longnamesfirst option works fine (with APA style references) when using \bibliographystyle{newapa}

Thank you, you made my day! (really!)
