PUBLICATIONS 



THE publications of the American Museum of Natural History 

 consist of the "Annual Report/' the "Bulletin," the "Me- 

 moirs," "Anthropological Papers," an " Ethnographical 

 Album," and the "American Museum Journal." 



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 Bulletin, 

 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. 



The "Memoirs," like the "Bulletin," are strictly scientific, but are 

 devoted to special articles requiring more exhaustive treatment. Memoirs. 

 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 establishment 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-
