Hardin MD:Infectious Diseases/Bacterial Diseases/Microbiology
As the name "meta directory" implies, Hardin MD is a "list of lists" - Its purpose is to provide easy access to comprehensive resource lists in health-related subjects. It includes subject listings in large "one-stop-shopping" sites, such as MedWeb and Yahoo, and also independent discipline-specific lists. Hardin MD subject pages indicate the length of lists in each subject, making it easy to see at a glance which lists are most comprehensive.
