  • What:
    • What is the source you're using?
    • What are its physical characteristics?
    • What was the historical, cultural, social, or political context in which the item was created?
    • What biases or assumptions may have influenced the creator?
  • Who:
    • Who was the author? Who created this source you're using?
    • Who preserved it?
    • Who was the intended audience? Was this source meant for the public or for an individual?
  • Where/When:
    • Where was this item created?
    • Where did this source come from? (A library database, an archive, a blog?)
    • When was this item created?
    • When was it published? 
  • Why:
    • Why was this item created? (What was its purpose? What was the creator's message or argument?)
    • Why was it made available? Was it meant to be private or was it intended for publication?
  • How:
    • How trustworthy is the creator? Did they actually witness or experience the event related to your item?
    • How does this source compare to other similar sources?
    • How is it presented? Has this source been edited, translated, or altered?
