Primary Source Analysis Guide
Reading cables, speeches, treaties, and memoirs in context — extracting signal from archival text.
Method
APPARTS method
AP History curriculum's primary-source analysis framework. Works for any document.
Author
Who wrote it? What do we know about their background, position, biases?
Place and time
When and where? What was happening around the author?
Prior knowledge
What do you already know about this context that will inform your reading?
Audience
Who was the intended reader? Contemporaneous or posthumous?
Reason
Why was this written? Persuasive? Informational? Record-keeping?
The main idea
In one sentence, what is the author trying to convey?
Significance
Why does this document matter? What does it reveal that other sources don't?
Sourcing vs content
Sam Wineburg's research shows historians read 'sourcing first' — the author and context — before engaging the content. Novices read content first. The habit transfers to everything: academic papers, news articles, memos.
Document Types
Diplomatic cables
Messages between embassies and foreign ministries. Usually highly formal, often cryptic, always filtered through the author's interests.
Key Points
- WikiLeaks 2010 Cablegate dump: 250K+ US State Department cables from 1966-2010.
- Format: classification (Unclassified / Confidential / Secret / Top Secret) + originator + addressees + subject.
- Read between the lines: what did the ambassador NOT say? What framing were they pushing on DC?
Political speeches
Key Points
- Audience shapes content. Home-crowd speech ≠ international audience speech.
- Check the venue, the occasion, and who was in the room.
- Compare delivered vs prepared text when available — extemporaneous departures matter.
- Rhetorical moves are information: who does the speech honor? Omit? Attack?
Treaties and declarations
Formal legal texts. Every word is fought over in negotiation. Read the preamble for political positioning; the text for obligations; the final clauses for escape hatches.
Memoirs and diaries
Key Points
- Memoirs are self-justifying. Great for the author's worldview; unreliable for 'what happened.'
- Diaries are more contemporary but still shaped by the author's assumed future reader.
- Cross-reference with other participants' accounts.
- Example: multiple accounts of the Cuban Missile Crisis (Kennedy, Sorensen, Khrushchev, Bundy) diverge in significant ways.
Worked Examples
Kennan's 'Long Telegram' (1946)
George Kennan's 8,000-word cable from Moscow shaped US Cold War policy for 40+ years.
Key Points
- Author: Kennan — US chargé d'affaires, Russia specialist, fluent in language and history.
- Context: post-Yalta disillusionment, Soviet uranium deposits, Iran crisis.
- Reason: State Department asked why Soviets were behaving this way.
- Main idea: Soviet expansionism is ideologically driven and must be contained with long-term patience.
- Significance: became the basis for containment doctrine (1947 'X Article' in Foreign Affairs).
Churchill's 'Iron Curtain' speech (March 1946)
Key Points
- Author: Winston Churchill, no longer PM, speaking as a private citizen (but with Truman present).
- Venue: Westminster College, Fulton, Missouri — deliberately chosen.
- Audience: American public via radio; Stalin in the secondary audience.
- Key line: 'From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent.'
- Significance: labeled the Cold War geographic divide for the next 45 years.
FAQ
Where do I find primary sources?

What about documents in other languages?
If you can't read the original, use translations from reputable scholars or institutions (not Google Translate for important work). Always note that you're working from translation — it's a dependency.
