I get an error when I try to use the uni-wtal-ger citation style and since I am fairly new to Latex I am unable to make sense of it (at all).

My usepackage declaration for biblatex looks like this:


This works for all citation styles I tried, including uni-wtal-lin, but not for uni-wtal-ger, which throws the following error:

LaTeX Warning: Reference `edtranslog' on page 3 undefined on input line 60.

! Package etoolbox Error: Boolean '\ifbbx:annotation' undefined.

This seems similar to this problem but the proposed solution there is to use biber which I already do. Any help is much appreciated.

(Dist: Arch Linux with texlive-most, texlive-lang and texlive-bibtexextra)

  • The style looks a bit old, notifiy the maintainer, perhaps they need to update it. Oct 12, 2020 at 10:13
  • @UlrikeFischer Thx, I contacted the maintainer.

  • Unless you know exactly why you are doing it, it is usually recommended not to use separate bibstyle and citestyle instructions, but load a single style with style. In your case citestyle=uni-wtal-ger, bibstyle=authortitle, should probably just become style=uni-wtal-ger,. biblatex allows you to select different citation and bibliography styles, but not all styles support the free 'mix-and-match-approach'. Some custom styles work under the assumption that both bibliography and citation style are set to the same value.

uni-wtal-ger is depending on biblatex-dw. Like many other custom styles, the citation and bibliography styles included in those packages are mutually dependent. So mixing uni-wtal-ger or biblatex-dw with other styles will lead to errors.

The style does still work perfectly when using it completely as citestyle and bibstyle though.

So please try

  • thank you very much, everything is working now!
