The CERN Open Data portal is the access point to a growing range of data produced through the research performed at CERN. It disseminates the preserved output from various research activities and includes accompanying software and documentation needed to understand and analyse the data.

Information from the Fermi National Accelerator Laboratory, operated by the US DOE.

The Durham High-Energy Physics Database (HEPData) has been built up over the past four decades as an open-access repository for scattering data from experimental particle physics. It currently comprises the data points from plots and tables related to several thousand publications including those from the Large Hadron Collider (LHC). HEPData is based at the IPPP at Durham University.

A self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. Further, it describes in detail the adjustment of the values of the subset of constants on which the complete set of recommended values is based.

NIST provides reliable datasets on elements, spectroscopy, nuclear and condensed matter physics, radiation, physical constants, and more.

The Review of Particle Physics is updated yearly and published every two years in a HEP journal. It includes a compilation and evaluation of measurements of the properties of known elementary particles and summarizes searches for hypothetical new particles.

NNDC is a worldwide resource for nuclear data, that collects, evaluates, and disseminates nuclear physics data for basic nuclear research and applied nuclear technologies.

Tables of nuclides, gamma rays, code libraries, etc.

Web application that allows users to search and plot nuclear structure and nuclear decay data interactively. It provides an interface between web users and several databases containing nuclear structure, nuclear decay and some neutron-induced nuclear reaction information. Using NuDat, it is possible to search for nuclear level properties (energy, half-life, spin-parity), gamma-ray information (energy, intensity, multipolarity, coincidences), radiation information following nuclear decay (energy, intensity, dose), and neutron-induced reaction data from the ENDF/B-VII.0 library (thermal cross section and fission yields).

There are many free periodic tables and nuclide data to choose from.

One of 17 DOE national laboratories.

The American Institute of Physics advances, promotes and serves the physical sciences for the benefit of humanity. AIP offers authoritative information, services, and expertise in physics education and student programs, science communication, government relations, career services for science and engineering professionals, statistical research in physics employment and education, industrial outreach, and the history of physics and allied fields.

The American Physical Society (APS) is a non-profit membership organization working to advance and diffuse the knowledge of physics through its outstanding research journals, scientific meetings, and education, outreach, advocacy, and international activities. APS represents over 51,000 members, including physicists in academia, national laboratories, and industry in the United States and throughout the world.

The American Association of Physics Teachers is a professional membership association of scientists dedicated to enhancing the understanding and appreciation of physics through teaching. AAPT provides resources for physics teachers as well as awards and grant opportunities.

The European Physical Society (EPS) is a not for profit association whose members include 42 National Physical Societies in Europe, individuals from all fields of physics, and European research institutions. As a learned society, the EPS engages in activities that strengthen ties among the physicists in Europe. As a federation of National Physical Societies, the EPS studies issues of concern to all European countries relating to physics research, science policy and education.

IOP, based in the UK, is both a scientific membership society and a major STEM publisher.

The Niels Bohr Library & Archives in College Park MD is a repository and clearinghouse for information in the history of physics, astronomy, geophysics and allied fields.
