Two Voices from the 1912 Lawrence Strike
A student researching the 1912 Lawrence, Massachusetts textile strike finds two sources. Source A is a Boston newspaper editorial from February 1912 calling the strikers 'foreign agitators' and praising police. Source B is a 1974 oral-history interview with a striker's daughter recalling that families shared bread and that police broke up a peaceful march. The student has 45 minutes, a library database, and one textbook paragraph. The student writes: 'The newspaper is biased, so the oral history is reliable and proves the strike was peaceful.' The assignment asks for a 300-word evidence-based paragraph, and the student has not yet opened the database.
1. Identify the reasoning error in the student's conclusion and explain what source criticism would require for each source.

The student commits a false dilemma: one source's bias does not make another source reliable. Source criticism asks about provenance, purpose, audience, genre, and temporal distance. The newspaper editorial is evidence of contemporary business and elite opinion and of how police action was framed; its bias is itself historical evidence, but it limits claims about what actually happened. The oral history is retrospective memory from 1974, shaped by family identity, aging, and later narratives about labor and civil rights. It can attest to family memory and community meaning, but it cannot by itself prove police behavior in 1912. Both sources are partial. Reliability is claim-specific, not a property of a whole document. To test the claim that the march was peaceful, the student should seek independent contemporaneous records such as other newspapers, police arrest logs, strike committee minutes, and court testimony, then check whether accounts were independent. The textbook can supply chronology, not a verdict. The correct move is corroboration and qualified claims, not swapping one biased source for another.
2. Design a 20-minute database search that would help test the claim that police broke up a peaceful march. Name source types and explain what each could establish.

Search the labor press, newspapers from other cities, and court or police records. Each source type has a different evidentiary value. The labor press may report striker testimony but has an advocacy purpose. Out-of-town newspapers may be less dependent on local elites but often rely on wire copy. Arrest logs can establish time, place, and charges but not whether a march was peaceful. Court testimony under oath can be cross-examined, but it reflects prosecution priorities. Search by date from January to March 1912, by names of strike leaders, and by terms such as parade, arrest, and clash. Record provenance and check whether accounts share a single origin. A 20-minute search cannot settle the claim, but it can show whether independent sources converge on the sequence of events and whether the word peaceful is disputed. The student should log what was not found, because absence in one database is weak evidence.
3. How should the student use both sources in the final paragraph without overclaiming?
Read the worked answer
The student should assign each source a distinct evidentiary role. The editorial can support a claim such as: Some Boston editors framed the strike as foreign radicalism and praised police, which shows contemporary elite opinion and rhetorical strategy. The oral history can support a claim such as: In one striker family's memory, the march was peaceful and the community shared food, which shows how participants' descendants constructed meaning. Neither alone proves the character of the march. The paragraph should state the claim, present the two sources as partial perspectives, note the missing independent records, and end with a qualified judgment, for example: The sources disagree about police conduct, and contemporary records are needed before calling the march peaceful. This models historical thinking: bias is not disqualification, memory is not transparent, and corroboration is the standard.
