UK Surface Analysis Forum
The Surface Analysis Forum is for scientists from academia and industry with a common interest in Electron Spectroscopy for Chemical Analysis and surface science in general. The site also includes an introduction on experimental techniques and links to online databases.

X-ray Photoelectron Spectroscopy Database
The XPS database gives easy access to the energies of many photoelectron and Auger-electron spectral lines. The database contains over 22,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines.
