# 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)
```
