In some subject areas, like health or psychology, you may need to find clinical trials, evidence based practice or papers that use specific methodologies like a meta-analysis or longitudinal study.

Discover@Bolton is great for finding journal articles across a broad range of subjects, but can't limit results to clinical trials or specific methodologies. For this you would need to use a Subject Database. 

You can find a full list of available databases via our A-Z of Databases. Or visit your Subject Guide to find the databases relevant to your subject area.

This isn't a complete list, but here are a few examples of how Subject Databases can help you find specific kinds of articles. 



The advanced search on CINAHL allows you to limit your search to Evidence Based Practice, Randomised Control Trials or types of publications such as Case Studies and Clinical Trials.

You can also limit your search by the sex and age range of patient populations.

You can find CINAHL and other relevant databases on our Subject Guides for Nursing



The Advanced Search on PsycInfo can limit results by publication type and methodology.

You can also limit results by population type.
