There can be multiple sources to collect secondary data. While it is easy to research and collect data for secondary purposes, it is also very effective in many terms.

Sources of secondary data:

  • Books
  • Unpublished Sources
  • Published Sources
  • Journal
  • Newspapers
  • Websites
  • Blogs
  • Diaries
  • Government Records
  • Podcasts

The only thing to keep in mind while collecting secondary data is the reliability and authenticity of it. For a dissertation, you need to be precise.
