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 11.2 million records covering publications in Astronomy and Astrophysics, Physics, and the arXiv e-prints.

The Weizmann Institute of Science Plasma Laboratory maintains a directory of databases for atomic and plasma physics.

The Durham HepData Project has for more than 30 years compiled the Reactions Database containing what can be loosely described as cross sections from HEP scattering experiments. The data comprise total and differential cross sections, structure functions, fragmentation functions, distributions of jet measures, polarisations, etc., from a wide range of interactions. They are all made publically available in the Reaction Data Database.
