Much of the work of disseminating news and research is done through professional associations. These organizations exist for researchers and practitioners to join in order to network, stay current with developments in the field, host conferences, and publish research. Many of the top journals in your field are published through professional associations. The American Medical Association (AMA) and the American Psychological Association (APA) are examples.
