The Wellcome Trust
"The Wellcome Trust is an independent research-funding charity that aims to improve human and animal health."
As well as providing a comprehensive guide to the Wellcome Trust, and providing access to the Wellcome Library for the History and Understanding of Medicine this site allows you to order online the publications supported by this independent trust (Wellcome News and the specialist supplements are particularly useful because of their scientific updates in genetics and cancer research).
The site also includes a section "A guide to cancer information on the internet" which not only provides an articulate discussion of the pros and cons of patients and professionals accessing information which is essentially unverified; it also provides quick inks to specialist cancer sites, medical information and teaching resources and cancer sites for the patients and public.
The site is easy to navigate, albeit mainly text as opposed to graphics, this nevertheless speeds up the time it takes to download pages.
