PUBLICATIONS 
THE publications of the American Museum of Natural History- 
consist of the "Annual Report," the "Bulletin," the 
"Memoirs," "Anthropological Papers," an " Ethnographical 
Album," and the "American Museum Journal." 
Bulletin. The "Bulletin" is a strictly scientific publication in which are pub- 
lished the shorter articles embodying the results of the research work 
of the various departments of the Museum. These papers are less 
voluminous and of more general interest than those which appear in 
the "Memoirs." The first number was issued in December, 1881 — 
the first year of President Jesup's administration — and the first volume 
was completed five years later. Since 1892 a complete volume has 
been issued every year. Each volume contains about twenty-four 
articles, published separately during the year, which relate about 
equally to Geology, Palaeontology, Mammalogy, Ornithology, and Ento- 
mology. It is octavo in size, and contains 400 to 975 pages, with many 
plates and text figures. It has an edition of 750 and is distributed 
mainly to other scientific institutions in exchange for their publica- 
tions, and is thus an important means for the increase of our Library. 
Memoirs. The "Memoirs," like the "Bulletin," are strictly scientific, but are 
devoted to special articles requiring more exhaustive treatment. 
The issue of "Memoirs" was suggested by Professor Osborn in 1892. 
Each part forms a separate and complete monograph, usually with 
numerous plates. The " Memoirs " are quarto in size, and have been 
published in parts at irregular intervals since 1893. The present edi- 
tion is 600 copies. 
The amount of material brought in and the observations made by 
the parties at work under the Jesup North Pacific Exploration Fund 
made necessary the estabhshment in 1898 of a special series of pub- 
lications in the " Memoir " form. At first these were issued by the 
Museum, but since 1904 they have been published by E. J. Brill, Ley-
