Wikipedia's reference list can lead a researcher to publications with identifiable authors. Following those references makes it easier to trace a claim and establish where an error originated. A collaborative article can change repeatedly, and its contributors may use names that do not identify them outside the site. The joke about finding someone to blame expresses a more useful research principle: citations should let a reader follow the chain of responsibility for a claim. A named source offers a clearer point of reference when checking or challenging historical information.
