A learned society, also known as a scholarly society or academic society, is an organization that brings together individuals who share a common interest in a particular academic or intellectual field. These societies are typically composed of experts, scholars, researchers, professionals, and enthusiasts who are dedicated to advancing knowledge and promoting research in their respective fields.
A very extensive list of early learned societies is available through the Internet Archive's Wayback Machine. The page for each learned society lists its publications. The titles of these publications changed frequently and cataloging rules required a separate catalog record for each title change. This can make it very difficult to pin down the location of all volumes. Look at the dates on the society's page to determine what title was used during the time period you are interested in. Then search for that title in UC Library Search.
