"The American Diabetes Association is the nation's leading nonprofit health organization providing diabetes research, information and advocacy."
This is a very good resource for patients, practitioners, care givers as well as the general public on numerous issues involved with diabetes.

This site has a Diabetes Research Database, "Access: Diabetes Research," which presents summaries of late-breaking research published in respected medical journals on diabetes and related conditions.
