Passage Summary: Logan thinks old newspapers are historical junk because they ignore the big stuff. Mendez thinks they are a goldmine because they show what regular people were thinking back then.

Reasoning: Logan claims old newspapers are useless to historians because they focus on the trivial; Mendez counters that they are valuable because they reveal the public's thoughts and feelings.

Analysis: The disagreement here centers on the utility of a specific source. Logan takes a hard line, calling old newspapers 'useless' for historical research. Mendez doesn't just disagree; she provides a specific reason why they are actually a 'wealth of information.' To find the point at issue, apply the 'Agree/Disagree' test: Logan would agree that they are useless, while Mendez would explicitly disagree. The core conflict is whether old newspapers have value for historians.
