# Primary Source Evaluation

Authenticate, date, and critically assess historical documents for provenance, reliability, and bias with systematic source criticism methodology.

## Overview

This skill enables rigorous evaluation of primary historical sources. It encompasses authentication, dating, provenance assessment, and bias analysis using systematic source criticism methodologies to support historical research.

## Capabilities

### Authentication
- Document analysis
- Handwriting examination
- Material assessment
- Seal and signature verification
- Forgery detection

### Dating Methods
- Paleographic analysis
- Content dating
- Cross-referencing
- Material dating
- Contextual placement

### Provenance Assessment
- Ownership history
- Chain of custody
- Archive documentation
- Publication history
- Collection context

### Bias Analysis
- Author perspective
- Purpose identification
- Intended audience
- Contemporary context
- Comparative assessment

## Usage Guidelines

### Evaluation Process
1. Establish source identity
2. Verify authenticity
3. Determine date and origin
4. Trace provenance
5. Analyze purpose and bias
6. Assess reliability
7. Document findings

### Source Criticism Questions
- Who created the source?
- When was it created?
- Why was it created?
- For whom was it intended?
- How has it been transmitted?
- What biases are present?

### Documentation Standards
- Record source metadata
- Note physical characteristics
- Document analytical methods
- Preserve findings
- Cite appropriately

Overview

This skill evaluates primary historical documents to authenticate, date, and assess provenance and bias using systematic source criticism methods. It supports researchers by producing structured findings about a document's origin, reliability, and context. The skill is designed to integrate with archival workflows and produce documented, reproducible conclusions.

How this skill works

The skill inspects physical and textual features—handwriting, materials, seals, and internal content—then applies paleographic, contextual, and cross-referencing techniques to estimate date and origin. It reconstructs provenance by tracing ownership, custody, and publication history and conducts bias analysis by evaluating author intent, audience, and contemporary context. Results are returned as structured metadata, diagnostic notes, and a reliability assessment with cited reasoning.

When to use it

  • Authenticating suspected forgeries or disputed documents
  • Dating undated manuscripts or letters
  • Tracing ownership and custody chains for archival items
  • Evaluating author bias and reliability for historical interpretation
  • Preparing source-critical apparatus for publication
  • Integrating evidence into archival or scholarly workflows

Best practices

  • Start by recording full source metadata and physical characteristics before analysis
  • Combine material analysis with paleography and internal content dating for robust results
  • Document every inference and the supporting evidence or references
  • Use comparative samples from the same period or archive when available
  • Flag degrees of uncertainty and alternative hypotheses clearly

Example use cases

  • Verify authenticity of a newly acquired museum letter and document the chain of custody
  • Estimate the date of an undated diary fragment using handwriting and contextual clues
  • Assess bias and intended audience of a political pamphlet to inform a historical narrative
  • Produce standardized provenance notes for digitized archival collections
  • Support peer review by providing transparent, evidence-based reliability ratings

FAQ

What types of sources can this skill evaluate?

Manuscripts, letters, legal deeds, seals, printed pamphlets, archival records, and other primary materials with physical or textual features to analyze.

How does the skill express uncertainty?

Findings include confidence levels, alternative hypotheses, and the evidence basis for each conclusion so users can weigh uncertainty in downstream use.
