I am about to start a term paper on the novella The Metamorphosis by Franz Kafka, and my teacher told the class to use only sources from published writers. That day for homework, she told us to find some resources on the 'net that we could use. One of my classmates brought in something, but my teacher said that the information the classmate brought in could not be used because they are not a published author, just some guy on the 'net giving his own word on the topic. Well, why not? Why should people who gives their own word on something be completely disregarded, and settle for someone else who is published?
Why does being a "published writer" matter?
