The Shorenstein Center on Media, Politics and Public Policy at the Harvard Kennedy School has assembled a guide to databases, with a focus on health and public health. Their list includes both free (open source) and paid access databases. Some, like PubMed or Public Library of Science (PLoS), are well known to health journalists but others, like the Social Science Research Network or HighWire, may not be. This is a comprehensive list, with descriptions, and it’s helpful.
