## Research Techniques

### Building a Timeline

1. **Start with overview** - Wikipedia, encyclopedia for basic timeline
2. **Find contemporary coverage** - News from the time
3. **Locate official records** - Government reports, investigations
4. **Add personal accounts** - Memoirs, interviews
5. **Cross-reference dates** - Verify against multiple sources
6. **Note discrepancies** - When sources disagree on dates

### Finding Contemporary Coverage

**Search pattern**:
```
"[event]" site:newspapers.com
"[event]" [year] site:archive.org
"[event]" newspaper [month] [year]
```

**Why contemporary matters**:
- Written before outcome known
- Captures uncertainty of moment
- Different framing than retrospective

### Accessing Archives

**Tips**:
- University libraries often have remote access
- Inter-library loan for books
- FOIA requests for government docs (slow)
- Contact archivists directly (helpful)

### Verifying Historical Claims

1. **Multiple sources** - Don't rely on single account
2. **Primary vs. secondary** - Prefer contemporary documents
3. **Consider perspective** - Who wrote it, why?
4. **Check for corrections** - Later scholarship may revise
5. **Note uncertainty** - Some things remain disputed
