Articles are rated from 1 to 5 with 5 being highest. Criteria in descending order of weighting:
Originality with the page. Highest weighting. Items written by the project or exclusively for the page. Project-generated items are also highlighted in red.
Out-of-the-way source. Next highest weighting. Items of significance that our readers are unlikely to have encountered elsewhere.
Quality of analysis. Logical argumentation supported by fact. Because more subjective, this criterion has less weight.
