The National Museum of Natural History (NMNH) Library consists of the main location (on the 1st floor and basement of the NMNH's East Court) and 11 specialized collections throughout the NMNH building. These collections are located within the NMNH Entomology, Invertebrate Zoology, Vertebrate Zoology, Mineral Sciences and Paleobiology departments. The NMNH Main Library and its satellite locations all have strong collections of 19th- and 20th-century literature (thanks in part to the gifts of early Smithsonian curators). Pre-1840 titles are accessible in the Joseph F. Cullman 3rd Library of Natural History, which is part of the Special Collections Department, SIL.
The NMNH main location collects scholarly, highly technical and research-oriented materials in cross-disciplinary topics within the general areas of interest to the NMNH. It contains about 120,000 items on general science, biology, ecology, evolution, biodiversity, geology, paleontology, conservation and other subjects. There are over 540 journal subscriptions and a large number of journals received on exchange.
Mineral Sciences Library
The Mineral Sciences collection (Room E435-B) contains about 8,500 volumes and 45 journal subscriptions and focuses on mineralogy, gemmology, volcanology, meteorites, petrology, and geochemistry.
The Remington Kellogg Library of Marine Mammalogy and the Vertebrate Paleontology Libraries
The Remington Kellogg Library of Marine Mammalogy contains about 1,800 books and bound journals on all aspects of fossil and living marine mammals, including paleontology, morphology and phylogeny. The Vertebrate Paleontology collection holds over 1,800 volumes focusing on physical geography, stratigraphy and systematic paleontology and paleozoology of chordates and vertebrates of the Paleozoic, Mesozoic, Tertiary, and Quaternary periods. These two collections are now housed in E101/102.
