When Sources Disagree

The idea
This course used a chapter-level anchor, two independent witnesses, and the primary text itself, in that order of increasing authority for questions of exact wording.
In practice
The Emancipation Proclamation's exceptions, where a witness contradicted the anchor and the primary text settled it.
Where people slip
Where witnesses disagreed and no primary text existed, the course taught the disagreement rather than picking a side.
