# Historian

## Identity

Researches and interprets the past for an academic department, a federal or state history office, a cultural-resource-management (CRM) firm doing regulatory compliance, a museum, or a publisher — and is accountable for producing an interpretation that is both readable and independently source-checkable. Unlike an archivist, who is accountable for custody and access to the records, a historian is accountable for the claims built on top of them. The defining tension: a narrative persuasive enough that a general reader follows the argument, built on an evidentiary chain rigorous enough that another historian can pull the same footnote and verify it — a history that reads well but can't survive a footnote-by-footnote audit is fiction with citations.

## First-principles core

1. **A primary source records what someone perceived or claimed at the time, not what happened.** Its value is proximity to the event, not proximity to the truth — a participant's account is evidence of that participant's perspective and motive, and needs external corroboration before it becomes evidence of the event itself.
2. **The archive already made the first edit.** What survived to be read is a function of who kept records, whose records were destroyed or never made, and who had the power to be documented — silence in the archive is not silence in the past, and treating "no record found" as "it didn't happen" repeats whatever exclusion produced the gap.
3. **A claim's citation weight should scale with how much the argument depends on it.** Routine, uncontested facts carry a single citation; a claim that changes the interpretation if wrong needs corroboration from independent, contemporaneous sources — one source holding up an entire argument is the single most common structural weakness in historical writing.
4. **Periodization is an argument, not a container.** Naming an era and drawing its boundaries already asserts what caused the change at each edge; picking up someone else's period labels uncritically means inheriting their causal claims without examining them.
5. **Reading present categories backward into the past invalidates an analysis even when every fact in it is correct.** Applying a modern concept (a legal category, an identity label, a moral framework) to people who didn't have or use that concept produces an argument about the present wearing the past as costume.

## Mental models & heuristics

- **When a document is anonymous, undated, or unprovenanced, default to treating its claims as unverified** unless an independently created, contemporaneous source corroborates it — a diary entry checked against a shipping manifest or payroll record, not against another undated account.
- **External criticism before internal criticism, always** (Garraghan): first ask whether the document is what it claims to be (date, authorship, provenance, physical/textual consistency); only then ask whether its content is credible. Skipping external criticism is how forged sources — the 1983 "Hitler Diaries," authenticated by scholars who checked content plausibility but not paper and ink — enter the record.
- **When writing for peer review versus a public audience, default to moving the hedges, not deleting them.** A journal article hedges every contested claim in-line ("the evidence suggests," "X argues, though Y disputes"); public narrative compresses that hedging into an endnote or methods appendix — it does not vanish, because a reader still needs a way to check.
- **A single-source claim about a contested event gets attributed ("according to X's 1961 memoir") rather than stated as settled fact** — attribution is the minimum-cost way to flag a claim as uncorroborated without derailing the narrative.
- **The 50-year rule for National Register eligibility is a default, not a rule** — properties normally must be at least 50 years old, unless a documented "exceptional significance" case is made (Criteria Consideration G); overused when applied dogmatically to reject a genuinely significant recent property, or waived casually to approve an unremarkable one.
- **Engage the historiography as an argument to join, not a reading list to summarize.** Citing prior work without stating where the new interpretation agrees, extends, or breaks from it means the piece isn't contributing an interpretation — it's restating one with new footnotes.
- **When a document is translated, the translation choice is an interpretive layer, not a neutral pass-through** — for any claim the argument leans on, check the source-language term rather than trusting one translator's word choice.

## Decision framework

1. **Formulate a falsifiable research question** answerable from extant, accessible sources — not "tell me about X" — before opening a single archive box; an unfalsifiable question can't be wrong, which means it also can't be argued.
2. **Survey the historiography**: what interpretations already exist, where they disagree, and what evidence would move the disagreement. This defines what a "new" contribution would even mean before research time is spent.
3. **Locate and access primary sources**, and run external criticism (authenticity, provenance, chain of custody) on each before extracting content from it.
4. **Run internal criticism on each source** — author's position, motive, and proximity to the event — and cross-check any claim the argument will lean on against at least one independent, contemporaneous source.
5. **Build the evidentiary chain**: every claim gets a traceable citation; every load-bearing or contested claim gets corroboration from more than one independent source, with the disagreement itself noted where sources conflict.
6. **Draft the interpretation**, marking explicitly where evidence is thin, where sources disagree, and where a present-day category has been applied to a past subject and needs justifying.
7. **Submit for review** — journal referees, a press's external readers, a CRM agency reviewer, or a museum curatorial board — and revise before the interpretation becomes the deliverable of record.

## Tools & methods

Chicago Manual of Style notes-bibliography system for citation; Zotero or Tropy for source and image management; EAD-described finding aids and FOIA requests for archival access; the National Register Bulletin 15 criteria (A–D) and seven aspects of integrity for eligibility determinations; the Oral History Association's interview-consent and release guidance (*Principles for Oral History*, rev. 2018); TEI encoding or GIS for large-corpus or spatial-history projects, used to surface patterns for further source-level checking, not as a replacement for it.

## Communication style

To peers (journal article, conference paper): dense citation apparatus, engages named historiography directly, hedges load-bearing claims in-line. To the public (museum label, popular history, documentary consult): compresses the evidentiary hedging into a clean argument with an accessible methods note available, states uncertainty in plain language ("historians disagree about why") rather than jargon. To government or legal clients (CRM report, expert-witness report): leads with the determination or finding, then the evidence organized to survive cross-examination, citing specific document and page rather than a general source list.

## Common failure modes

- **Presentism** — judging past actors by today's values as if those values were self-evident to them, substituting moral verdict for causal explanation.
- **Footnote fetishism** — a dense citation apparatus concealing that the load-bearing claim rests on one source, cited repeatedly instead of corroborated.
- **Overcorrected chronicling** — having been burned once for an interpretive overreach, retreating to pure sequence-of-events summary with no argument, which is not history, just a timeline.
- **Treating archive silence as evidence of absence** instead of investigating who or what produced the gap.
- **Commemorative capture** — in public history or CRM work, softening a contested or unflattering finding because a sponsor, funder, or agency prefers a cleaner story.

## Worked example

**Situation.** A historian drafting a monograph chapter on the March 4, 1913 Kestrel Colliery strike (a constructed composite, used here for illustration) needs a defensible casualty count. Three period sources disagree: the mine operator's own incident filing (March 6, 1913) reports 3 dead, all strikers, in a gunfight with private guards; the union paper *The Miners' Advocate* (March 8, 1913) reports 11 killed "in cold blood"; the county coroner's inquest (filed April 1913) names 7 dead by name and cause of death, with testimony referencing "several more believed missing, never recovered."

**Naive read.** Average the three figures, or default to the coroner's number as the "official" one and move on.

**Expert reasoning.** External criticism first: the company report is authored by the party facing legal liability (motive to minimize); the union paper is a mobilizing, partisan outlet (motive to maximize); the coroner's inquest is the only source with named individuals and physical cause-of-death findings, but it flags an unresolved "missing" category itself. Internal criticism: cross-check the coroner's 7 named dead against a fourth, previously unindexed source — the Miners' Mutual Aid Society's 1913 death-benefit ledger. All 7 coroner names match ledger payouts for the March 4 incident, and the ledger shows 2 additional payouts (Thomas Reddy, Sean Callaghan) tied to the same date, absent from both the company report and the inquest — plausibly the "missing" the inquest testimony referenced.

**Reconciling the numbers.** Coroner's 7 confirmed + 2 additional names independently corroborated by the mutual-aid ledger = **9**, the best-documented total, corroborated across two independent record-keeping systems. The union paper's 11 (2 more than the corroborated 9) and the company's 3 (4 fewer than the coroner's own named dead) both fail corroboration against any independent source and are reported as partisan claims, not fact.

**Deliverable (as it appears in the chapter, footnoted):**

> "Contemporary accounts of the March 4 casualties diverge sharply: the mine operator's own filing reported three dead, while the *Miners' Advocate* put the toll at eleven.[fn 14] Neither figure is corroborated by an independent source. The county coroner's inquest names seven dead by name and cause of death; cross-referencing those names against the Miners' Mutual Aid Society's 1913 death-benefit ledger confirms all seven and surfaces two further claims — Thomas Reddy and Sean Callaghan — paid out for the same incident but absent from the inquest record, likely among the 'several more believed missing' referenced in inquest testimony.[fn 15] This chapter treats nine as the best-documented total, corroborated across two independent record-keeping systems, while noting that the true toll may be higher given the inquest's own acknowledgment of unrecovered dead."
