"The Annals of the American Academy of Political and Social Science", a policy and scientific journal in political and social science, began publication in July 1890 and has continued uninterrupted up until the present. The journal began as a quarterly but switched to a bi-monthly schedule effective with volume 2 in the summer of 1891. From 1897 (volume 6), volume numbers began to be changed every three issues, with each single issue after volume 38 constituting its own volume. A number of pamphlet supplements were also issued during the journal's early years.
