The author was a high-ranking government official, and as such he had a particular agenda. The book's purpose was to try to justify the imprisonment of the Japanese-Americans while trying to show the camps in a positive light. Where the author of the first book detailed the inadequate living conditions to which she and her family were subjected, the government official's book showed pictures of barracks furnished like houses, including a picture of a Japanese-American family sitting on a couch together reading a book as if they were having quality family time at home. They looked happy, and not at all like prisoners. With the increased use of the Internet, the use of biased material is becoming more and more of a problem.
People can put up web pages of their own regardless of the accuracy of their contents.
Furthermore, these contents are uncensored, so people can say just about anything on their pages. Searching the web, he inadvertently came across a neo-Nazi site. This site claimed that the Holocaust never existed, and the student, not having done the proper research, took this site at face value and submitted a report that the holocaust never existed. So my point is that when using primary references, be aware of any bias. This is not to say that biased primary references are not useful.
