The present list and index have been compiled in the Editorial Division of the Smithsonian Institution. Forty years have elapsed since the publication of the first list and index in 1902, so the present work is overdue. Inasmuch as the publication (i.e., the "diffusion of knowledge") is one of the two prime functions of the Smithsonian Institution, another complete list is especially appropriate this year (1946) when the one-hundreth anniversary of the Institution's found is being observed. Publications of the National Museum have appeared in five series as follows: Annual Reports, Bulletins, Proceedings, Special Bulletins, and Circulars.
