Can a historian add details that are not present in one cited source by drawing on other evidence?
Short answerYes, through a synthesized reference, but the writer must disclose that multiple sources were combined and identify all of them.
NotesThe prompt raises a dispute over an author supplying details that were not present in one cited source. Historians may combine several sources to support one point, a practice called a synthesized reference. The method is not a license to blur provenance. The writer must indicate that several sources were used and point readers to all of them.
