2 secondary sources meaning scholarly books written by a university professor. Any book in the campus library will fulfill this requirement. If you find books elsewhere and are unsure look inside the book since many provide a biography of the author. Also you can check the publisher; if the publisher is a university press it is fine. Journal articles are also acceptable to fulfill this requirement and the campus library is full of scholarly journals. Another good place to find the journal articles is online on JSTOR which is accessible through the campus library website. Remember these articles must come from scholarly journals such as the Journal of Roman Studies or the Journal of Asian Studies. Articles from magazines such as National Geographic or Newsweek do not count.
