Learned society

A learned society (also known as a learned academy, scholarly society or academic association) is an organization that exists to promote an academic discipline or profession, or a group of related disciplines or professions. Membership may be open to all, may require possession of some qualification, or may be an honor conferred by election.

Most learned societies are non-profit organizations, and many are professional associations. Their activities typically include holding regular conferences for the presentation and discussion of new research results and publishing or sponsoring academic journals in their discipline. Some also act as professional bodies, regulating the activities of their members in the public interest or the collective interest of the membership.
