What is a primary source?

THIS PAGE IS UNDER CONSTRUCTION.

A primary source is a first hand account.  Among the type of documents general considered primary sources are:

  • What people say (speeches, interviews).
  • What people write (books, papers, letters, emails, blogs).
  • Newspapers.
  • Government documents.
  • Laws, regulations, court decisions, treaties.
  • Statistics.

Often an old publication, e.g. anything before the twentieth century, is considered a primary document. The reasoning being that it is a first hand account of that time period.

Sometimes, secondary sources, such as scholarly journal or magazine articles, are considered primary sources. It depends on the subject of study. For example, a study of popular culture in the nineteenth century would use magazines as a primary source.  Similarly, topics in intellectual history would use journal articles as primary documents.
