Health Science: Finding Grey Literature

This guide contains resources and guidance to help students completing the Bachelor of Health Science.

What is grey literature?


The term grey literature refers to published and unpublished research, such as reports, government documents, and presentations which you can find simply through Google!

Grey literature is often the best source of up-to-date research as you don’t have to wait for it to go through the publication process. Grey literature usually is not found on the library website or in databases.

Grey literature does not go through the same peer-review process as journal articles. However, it can still be a reliable resource for you to use. Just make sure that you evaluate grey literature before using it.



Grey Literature is a valuable resource for all health students, from government and non-government organisation (NGO) reports to guidelines, policy and statistics. They often contain an overview of an issue as it applies to a specific region, state, country or even worldwide.

NGO reports

You can also try searching other NGOs or Organisations that are specific to diseases and conditions you are researching, such as DiabetesAustralia.
