The scholarly and scientific publications of the United States National Museuminclude two series, Proceedings of the United States National Museum and United StatesNational Museum Bulletin.

In these series, the Museum publishes original articles and monographs dealingwith the collections and work of its constituent museums—The Museum of NaturalHistory and the Museum of History and Technology—setting forth newly acquiredfacts in the fields of anthropology, biology, history, geology, and technology. Copiesof each publication are distributed to libraries, to cultural and scientific organizations,and to specialists and others interested in the different subjects.

The Proceedings, begun in 1878, are intended for the publication, in separateform, of shorter papers from the Museum of Natural History. These are gatheredin volumes, octavo in size, with the publication date of each paper recorded in thetable of contents of the volume.

In the Bulletin series, the first of which was issued in 1875, appear longer, separatepublications consisting of monographs (occasionally in several parts) and volumesin which are collected works on related subjects. Bulletins are either octavo orquarto in size, depending on the needs of the presentation.
