Physics, Earth Science, and Astronomy Research Guide

The online edition ASFA 1: Biological Sciences & Living Resources. ASFA 1 provides extensive coverage of basic and applied research on aquatic organisms. Coverage is 1971 - present.

The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 13.4 million records covering publications in Astronomy and Astrophysics, Physics, and thearXiv e-prints.

The GeoRef database, produced by the American Geosciences Institute, is focused on comprehensive coverage of geoscience literature published worldwide. The content is indexed with geoscience terms from the GeoRef Thesaurus, and geolocation data (latitude/longitude) is also assigned, when applicable. GeoRef is the most in-depth A&I database available for geoscience literature and research. It helps researchers to address some of the most urgent environmental concerns, such as: Continuing need for natural resources including critical minerals and fossil fuels, critical shortages in clean water supplies, preparedness for natural disasters – earthquakes, tsunamis, and developing changes in climate.

Includes online access to the full-text of more than 30 peer-reviewed journals in the earth sciences and geology. All titles have backfiles to 2000 and some have complete runs back to 1911.

GreenFILE offers well-researched information covering all aspects of human impact to the environment. Its collection of scholarly, government and general-interest titles includes content on global warming, green building, pollution, sustainable agriculture, renewable energy, recycling, and more. The database provides indexing and abstracts for more than 384,000 records, as well as Open Access full text for more than 4,700 records.

Online version of the classic and well-known reference originally published from 1926 - 1930 for the National Research Council. It contains an enormous amount of critical data on inorganic and organic compounds, and pure substances. Featuring physical, thermodynamic, mechanical, and other key properties, it is a major reference source used by those involved in chemistry, physics, and engineering.

Originally published by Smithsonian Institution Press, this classic reference source comprises 901 tables of general interest to scientists and engineers, and of particular interest to those involved with physics in its larger sense. All entries in the index are hyperlinked to their page numbers.
