The original question of this thread (Dashed=true option in biblatex gives biblatex2.sty error), was addressed by @JosephWright below, and should be kept for future reference.

As I understood better the nature of the problem, I decided to edit the original title and provide an answer to it below. I also deleted my old comments so as to clean up the thread.

I use \RequirePackage[backend=biber,sorting=nyt]{biblatex}

  • dashed is an options for individual styles, not the biblatex core: does style sbl say it supports dashed? (I'm not familiar with the sbl style.) – Joseph Wright Sep 6 '14 at 19:42
  • Please add that (important) information to the question – Joseph Wright Sep 6 '14 at 20:01

The dashed option is not built in to biblatex but is provided by some of the standard styles: authoryear and derivatives. In authoryear.bbx you will find


along with


and use of this new macro in various places.

Thus to provide the dashed option a custom style must either load authoryear and make changes or contain the above lines (or a variant thereof).


This macro, inserted in my .def file, produces a horizontal line, period, and space for different bibliography items by the same author.

The height of the line can be adjusted by "ex" and the length by "em"

  \leavevmode\raise -0.4ex\hbox to 5.5em{\hrulefill}.\space}

    test {\iffieldequals{fullhash}{\bbx@lasthash}}
    not test \iffirstonpage
