National Knowledge Weeks aim to highlight the best current evidence for selected healthcare topics - they consist of the good quality evidence from an Annual Evidence Update (a search of research evidence on a particular topic over a 12 month period), plus user-friendly summaries written by relevant experts, and links to guidelines, secondary research and primary research, if applicable. All information included in National Knowledge Weeks has been subject to rigorous selection criteria.

The National Library for Health (NLH) Specialist Libraries have been developed to identify and meet the information needs of particular communities of practice. They are web-based collections containing clinical and non-clinical information on the major health priority areas. Each NLH Specialist Library identifies and provides access to quality assessed information of relevance to the community that it serves.
