# Validate Bibliography Cross-reference all citations in lecture files against bibliography entries. ## Steps 1. **Read the bibliography file** and extract all citation keys 2. **Scan all deck files for citation keys:** - `.qmd` files: look for `@key`, `[@key]`, `[@key1; @key2]` - Extract all unique citation keys used 3. **Cross-reference:** - **Missing entries:** Citations used in lectures but NOT in bibliography - **Unused entries:** Entries in bibliography not cited anywhere - **Potential typos:** Similar-but-not-matching keys 4. **Check entry quality** for each bib entry: - Required fields present (author, title, year, journal/booktitle) - Author field properly formatted - Year is reasonable - No malformed characters or encoding issues 5. **Report findings:** - List of missing bibliography entries (CRITICAL) - List of unused entries (informational) - List of potential typos in citation keys - List of quality issues ## Files to scan: ``` Quarto/*/*.qmd # decks are one level down, under their genre Quarto/lectures/_series/*/*.qmd # shared include slides, rendered into series decks ``` (`python3 scripts/deckpath.py --list` names every deck.) ## Bibliography location: ``` Bibliography_base.bib (repo root) ```
