Reasonableness - What kind of page is this?

Checking Reasonableness:

  • What is the domain type? (.com, .gov, .edu, .org, etc.)
  • What is the purpose of the page? is the author advocating a point of view, marketing merchandise/services, educating or providing information, communicating news, entertaining, or providing personal information?
  • Does the page present controversial information? Are the opposing points of view represented or acknowledged?
  • Does the page contain advertising? If so, can you tell the promotional material from the information elsewhere on the page?

Warning Signs:

  • Insulting tone or language (e.g. "Annoying Librarians")
  • Sweeping statements (e.g. "Librarians are the most important people EVER!")
  • Conflict of Interest (e.g. "Welcome to the Society for Promoting Librarians. Click here to read our report on how librarians can help you live longer!")
