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. An aspect of this involves the production of Annual Evidence Updates, which aim to highlight the best current evidence for selected healthcare topics. Annual Evidence Updates consist of the good quality evidence from 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 Annual Evidence Updates has been subject to rigorous selection criteria.
