I'm trying to use the authortitle option described in the manual for biblatex-chicago. I've tried


but I get Package keyval Error: authortitle undefined. I've made sure I'm running the latest version (2.2). Am I missing something?

Looking at the code we see that the option authortitle is defined on the per-entry and per-type level, but not globally. chicago-dates-common.cbx has


So you cannot say authortitle=false, at load-time, but you can say


(As far as I know this is the only relevant setting you have to counter, because biblatex-chicago only sets authortitle=true, for @dataset entries, all other types are not affected.)

  • This didn't work for me, ! Package xkeyval Error: `authortitle' undefined in families `blx@opt@typ'. Any ideas? Jun 20, 2023 at 13:13
  • @jessexknight The example at gist.github.com/moewew/a3bb2524fcd1e01d12a22ec9ae010311 compiles fine for me (no errors) and the authortitle option appears to be working as advertised. I should note that I tested this with the current version of biblatex-chicago (2022/07/02, v2.3a). If you are using an older version, you might get errors.
