Source criticism[edit]
Main article: Source criticism
Source criticism (or information evaluation) is the process of evaluating the qualities of an information source, such as its validity, reliability, and relevance to the subject under investigation.
Gilbert J Garraghan divides source criticism into six inquiries:[1]
1.When was the source, written or unwritten, produced (date)?
2.Where was it produced (localization)?
3.By whom was it produced (authorship)?
4.From what pre-existing material was it produced (analysis)?
5.In what original form was it produced (integrity)?
6.What is the evidential value of its contents (credibility)?
