Evidence searching and critical appraisal

NHS Knowledge and Library Hub

The NHS Knowledge and Library Hub is the simplest way to find books, e-books, articles and much more. It is the best place to start your search.

Finding primary research

If you don't find what you're looking for in the Knowledge Hub then you should consult one of our other databases. Each database covers a different area of research so some will be more appropriate for your question than others. 

To identify which databases you should search consult our guides for different professional roles or our guides for different health specialisms. These outline the key databases for different areas.
