Science today is published overwhelmingly in journals.
Depending on their field, young scientists measure their careers not only in degrees granted and jobs won, but in articles published in Nature , Cell , or American Physical Review Letters . Having published their articles, many older scientists judge their success by election to review boards and academies. Journals and professional societies are two of the fundamental organizing principles of science in the twentieth century. This was not always the case. This exhibition offers a glimpse of the ways ideas were disseminated and science was organized in the years just before and after the invention of journals and academies.
