Development of the national electronic library for mental health: providing evidence-based information for all.

There has been an explosion of mental health literature available on the Internet over the past 5 years, with current estimates placing the number of health related Websites at over 100,000. The scope and depth of each site is unique and this serves to contribute to the difficulty of finding reliable, high-quality literature. This paper details efforts being made within the UK to provide high quality, evidence-based mental health literature for patients, clinicians and health policy makers as part of the National electronic Library for Health project.
