Companion plugin
This plugin pairs with Bluebook Citations Fixer, which rewrites Zotero’s citation output to apply Bluebook rules CSL can’t express cleanly (hereinafter, journal volume/year, book pincites, and a manual “Break id.” fix). The two are built for the same law-review workflow and are meant to be used together — installing both is recommended.
