- [ ] DOIs resolve correctly to the article
- [ ] No DOI prefix in the BibTeX field (no "doi:" or "https://doi.org/")
- [ ] Metadata from CrossRef matches your BibTeX entry
- [ ] Run: `python scripts/validate_citations.py references.bib --check-dois`

### ✓ Formatting Consistency

- [ ] Page ranges use double hyphen (--) not single (-)

- [ ] Author names use "and" separator (not semicolon or ampersand)
- [ ] Capitalization protected in titles ({AlphaFold}, {CRISPR}, etc.)
- [ ] Month names use standard abbreviations if included
- [ ] Citation keys follow consistent format

### ✓ Duplicate Detection

- [ ] No duplicate DOIs in bibliography
- [ ] No duplicate citation keys
- [ ] No near-duplicate titles
- [ ] Preprints updated to published versions when available
- [ ] Run: `python scripts/validate_citations.py references.bib`

### ✓ Special Characters

- [ ] Chemical formulas properly formatted
- [ ] No unescaped special characters (%, &, $, #, etc.)

### ✓ BibTeX Syntax

- [ ] Run: `python scripts/validate_citations.py references.bib`

### ✓ File Organization

- [ ] Consistent formatting throughout
- [ ] No formatting inconsistencies between entries
- [ ] Run: `python scripts/format_bibtex.py references.bib --sort year`

## Automated Validation

### Step 1: Format and Clean

```bash
python scripts/format_bibtex.py references.bib \
  --deduplicate \
  --sort year \
  --descending \
  --output clean_references.bib
```

**What this does**:
- Removes duplicates
- Standardizes formatting
- Fixes common issues (page ranges, DOI format, etc.)
- Sorts by year (newest first)

### Step 2: Validate

```bash
python scripts/validate_citations.py clean_references.bib \
  --check-dois \
  --report validation_report.json \
  --verbose
```

**What this does**:
- Checks required fields
- Verifies DOIs resolve
- Detects duplicates
- Validates syntax
- Generates detailed report

### Step 3: Review Report

```bash
cat validation_report.json
```

**Address any**:
- **Errors**: Must fix (missing fields, broken DOIs, syntax errors)
- **Warnings**: Should fix (missing recommended fields, formatting issues)
- **Duplicates**: Remove or consolidate

### Step 4: Final Check

```bash
python scripts/validate_citations.py clean_references.bib --verbose
```

**Goal**: Zero errors, minimal warnings

## Manual Review Checklist

### Critical Citations (Top 10-20 Most Important)

For your most important citations, manually verify:

- [ ] Visit DOI link and confirm it's the correct article
- [ ] Check author names against the actual publication
- [ ] Verify year matches publication date
- [ ] Confirm journal/conference name is correct
- [ ] Check that volume/pages match

### Common Issues to Watch For

**Missing Information**:
- [ ] No DOI for papers published after 2000
- [ ] Missing volume or page numbers for journal articles
- [ ] Missing publisher for books
- [ ] Missing conference location for proceedings

**Formatting Errors**:
- [ ] Single hyphen in page ranges (123-145 → 123--145)
- [ ] Ampersands in author lists (Smith & Jones → Smith and Jones)
- [ ] Unprotected acronyms in titles (DNA → {DNA})
- [ ] DOI includes URL prefix (https://doi.org/10.xxx → 10.xxx)

**Metadata Mismatches**:
- [ ] Author names differ from publication
- [ ] Year is online-first instead of print publication
- [ ] Journal name abbreviated when it should be full
- [ ] Volume/issue numbers swapped

**Duplicates**:
- [ ] Same paper cited with different citation keys
- [ ] Preprint and published version both cited
- [ ] Conference paper and journal version both cited

# Option 3: Google Scholar

# Re-extract metadata
python scripts/extract_metadata.py --doi CORRECT_DOI
```

### Missing Information

```bash
# Extract from DOI
python scripts/extract_metadata.py --doi 10.xxxx/yyyy

# Or from PMID (biomedical)
python scripts/extract_metadata.py --pmid 12345678

# Or from arXiv
python scripts/extract_metadata.py --arxiv 2103.12345
```

### Duplicate Entries

```bash
# Auto-remove duplicates
python scripts/format_bibtex.py references.bib \
  --deduplicate \
  --output fixed_references.bib
```

### Formatting Errors

```bash
# Auto-fix common issues
python scripts/format_bibtex.py references.bib \
  --output fixed_references.bib

# Then validate
python scripts/validate_citations.py fixed_references.bib
```

## Long-Term Best Practices

## Tool Quick Reference

### Extract Metadata

```bash
# From DOI
python scripts/doi_to_bibtex.py 10.1038/nature12345

  --doi 10.1038/nature12345 \
  --pmid 12345678 \
  --arxiv 2103.12345 \
  --output references.bib
```

### Validate

```bash
# Basic validation
python scripts/validate_citations.py references.bib

# With DOI checking (slow but thorough)
python scripts/validate_citations.py references.bib --check-dois

# Generate report
python scripts/validate_citations.py references.bib \
  --report validation.json \
  --verbose
```

### Format and Clean

```bash
# Format and fix issues
python scripts/format_bibtex.py references.bib

# Remove duplicates and sort
python scripts/format_bibtex.py references.bib \
  --deduplicate \
