Source Analysis Basics

A source is any surviving trace of the past — a piece of evidence left behind by people who lived through the events you are studying. Working with sources is one of the most important skills in GCSE History because it is what historians actually do. Every board tests it, and every board rewards students who read sources carefully before they judge them.

What Counts as a Source?

A primary source is created at or near the time of the events it concerns. A secondary source is created later, usually by a historian analysing primary evidence. GCSE exams focus overwhelmingly on primary sources for AO3 questions.

Source family	Examples
Written	Letters, diaries, government records, newspapers, speeches, treaties, memoirs
Visual	Paintings, photographs, political cartoons, propaganda posters, maps, film stills
Oral	Speeches (recorded), oral history interviews, recorded testimony
Material	Buildings, archaeological finds, coins, weapons, objects, clothing
Quantitative	Census data, trade statistics, election results, parish registers

Every type has its own strengths and weaknesses, but the reading technique below applies to all of them.

The Three-Pass Reading Technique

Good source analysis is not a single action; it is a sequence of progressively deeper reads. Students who rush to judgement on a first read consistently miss marks.

flowchart LR
    A[First pass: What does it SAY?] --> B[Second pass: WHO, WHEN, WHY?]
    B --> C[Third pass: What does it REVEAL between the lines?]
    C --> D[Now you can judge it]

First pass — what does it say?

Read the source through once, simply to understand its surface meaning. Underline the key claim or claims. If it is a visual source, identify every object, figure and symbol you can see. Write a one-sentence summary: "This source says that…"

Second pass — who, when, why?

Now read the attribution line carefully. Every exam source comes with a caption telling you who produced it, when, and often why. This is your provenance data. Ask:

• Who wrote or made it? What was their position, role, nationality, class?
• When was it produced — during the event, immediately after, years later?
• Why was it produced — private reflection, public persuasion, official record, personal attack?
• For whom — a private audience, a mass audience, a government, a friend?

Third pass — what does it reveal between the lines?

The deepest reading asks what the source shows unintentionally. A propaganda poster trying to make you support a war also reveals what its government feared you were thinking. A letter home from a soldier that plays down danger reveals the existence of danger by the very effort to play it down. This "implicit" reading separates mid-band from top-band answers.

Worked Example 1: A Short Written Source

Source A: From a letter written by a British factory owner to a newspaper, May 1833.

"The proposal to restrict the hours that children may work will ruin English industry. My own child workers are well cared for, paid fairly, and far happier in my factory than they would be wandering the streets. I speak as a Christian and a father."

First pass (what it says): The author opposes restrictions on child labour and claims his own child workers are well-treated.

Second pass (who, when, why): A British factory owner writing in 1833 — the year the Factory Act was debated and passed. He writes to a newspaper, so his audience is the reading public, and his purpose is to influence public opinion against reform. He has a direct financial interest in children continuing to work long hours.

Third pass (between the lines): His defensive language ("well cared for", "fairly", "happier") suggests the opposite was widely reported — otherwise he would not need to rebut it. His appeal to Christianity and fatherhood shows that moral and religious arguments were being deployed against child labour, and he is trying to reclaim those frames. The letter reveals not only its author's views but the existence and force of a reform movement.

Worked Example 2: A Visual Source

Source B: A British recruitment poster from 1915 showing a father in an armchair, his daughter on his knee and his son playing with toy soldiers on the floor. The caption reads: "Daddy, what did YOU do in the Great War?"

First pass: The poster imagines a future in which a child asks her father what he did during the war.

Second pass: Produced by the British government in 1915, after the initial rush of volunteers had slowed and before conscription (introduced January 1916). The audience is men of military age who had not yet enlisted.

Third pass: The poster targets shame and masculinity rather than patriotism directly. The father's uncomfortable expression implies that not fighting is something he will have to answer for. The toy soldiers at the son's feet suggest that fighting is natural and admirable. The poster tells us that by 1915 voluntary recruitment was failing and the government was resorting to emotional coercion — one of the pressures that led to conscription.

Worked Example 3: A Quantitative Source

Source C: Extract from a table of Russian industrial output, 1928–1940 (from Soviet official statistics):

Product	1928	1940
Coal (million tonnes)	35.4	166
Steel (million tonnes)	4.0	18.3
Electricity (billion kWh)	5.0	48.3

First pass: Dramatic increases in all three categories.

Second pass: Soviet official statistics, covering the First, Second and part of the Third Five-Year Plans. The source is produced by the state that is being praised by the numbers. Purpose: almost certainly to demonstrate the success of planned industrialisation.

Third pass: The source is useful as evidence of the scale of Soviet industrial transformation, which no serious historian doubts. But because the statistics are produced by the regime measuring its own success — and because Soviet targets created strong incentives to inflate figures — the precise numbers should be treated cautiously. The source is more reliable for order of magnitude than for exact values.
