Government bodies frequently publish reports and studies on topics relevant to health science. In Canada, government bodies at both the national and provincial levels produce relevant material.
Many institutions have institutional repositories, online databases of publications by their members. These can include publications by faculty and student dissertations and theses.
Conferences are nodes of new research, often featuring studies before they appear in journals.
Students conduct both systematic reviews and original studies for their theses and dissertations. These texts are not usually included in major databases.
U of T’s Theses and Dissertations in the Sciences research guide is an excellent resource, with links for both U of T theses and dissertations and those from other institutions.

Newspapers and magazines can be helpful sources of non-academic information. While the information in newspapers might not be acceptable as a source of scientific evidence, newspapers can often point you to key references or provide a source of evidence for public opinion.
U of T's research guide on Newspapers includes thorough information and some databases that also index magazines. You can also look up individual magazines in the library catalogue to determine our access.
Sometimes, the best way to find grey lit is to search the Web. Different search engines have their own search algorithms that will pick up different results.
When searching Google, it helps to use versions from different countries. If you are looking for grey lit from the UK, for example, use Google UK to find results from that country. This list links to all Google domains for different countries.
