Each field of study has its own world of sources, conventions, and vocabularies. The list that follows is not all-inclusive, but will help you to identify primary sources in your own discipline. In general, personal correspondence and diaries or journals are considered to be primary sources by all disciplines. If you are unsure that a source is considered primary by your discipline, ask your professor or a reference librarian for assistance.
