CINDA contains bibliographic references to measurements, calculations, reviews, and evaluations of neutron cross-sections and other microscopic neutron data; it also includes index references to computer libraries of numerical neutron data available from four regional neutron data centers.
Contains over 5.5 million e-prints in basic and applied sciences, primarily in physics but also including subject areas such as chemistry, biology and life sciences, materials science, nuclear sciences and engineering, energy research, computer and information technologies, and other disciplines of interest to DOE.
eprintweb.org is an e-print service in the fields of physics, mathematics, non-linear science, computer science, and quantitative biology, and consists of e-print records which can be browsed and searched.
The Physics and Astronomy Classification Scheme® (PACS) was developed by the American Institute of Physics (AIP) and has been used in Physical Review since 1975 to identify fields and sub-fields of physics. It is used in a variety of ways, for example, in the online journals as a tool in searching for articles by subject. PACS is arranged hierarchically, by subdivision of the whole spectrum of subject matter in physics- and astronomy-related sciences into segments and then repeating the process of subdivision down to four levels.
