Bluebook Citations Fixer

⚠️ Beta / experimental. This plugin is in active development and likely buggy. Install only if you want to help beta test and are comfortable reporting issues. Back up any document you run it against.

Rewrites Zotero's citation output inside the integration pipeline to apply Bluebook rules that CSL alone can't express cleanly. Runs automatically on every insert/refresh.

Install: Download Bluebook_Citations_Fixer_v0.1.10.xpi

Current rules:

• Hereinafter (Rule 4.2(b)) — When a document cites multiple works by the same author, appends [hereinafter <i>Short Title</i>] to each work's first full cite and rewrites subsequent supra note cites to include the short title (e.g. Epps, supra note 1 → Epps, <i>Adversarial Asymmetry</i>, supra note 1). Skips Id. cites, including signal-prefixed forms like See id.
• Journal volume/year — Suppresses the trailing (YYYY) parenthetical for journal articles when the volume number itself is a four-digit year-like value.
• Book , at — When a book title ends in a numeral, rewrites bare page locators into the Bluebook , at <page> form to avoid ambiguous output like ... 1868 45 (2006).

Platform: Word and LibreOffice (RTF output). Google Docs not yet supported.
