The Bibliographical Society of America (BSA) is the only scholarly society in the United States whose primary focus is the study of books and manuscripts as physical objects. It was organized in 1904 and incorporated in 1927 with the principal objectives of promoting bibliographical research and issuing bibliographical publications. These objectives have been and continue to be accomplished through a broad array of activities, including meetings, lectures, and fellowship programs, as well as the publishing of books and the Papers of the Bibliographical Society of America (PBSA), North America’s leading bibliographical journal.
