Version 2.2
July 2005		 Updated the links for the "Atomic Spectra Database" to access the new version, Version 3.0.
Version 2.1
August 2004		 Added access to two new, online databases: "Energy Levels of Hydrogen and Deuterium" for H and "Potential Energy Surface Database of Group II Dimer Molecules" for Mg, Ca, Sr & Ba; and added access to "Electron-Impact Cross Sections for Ionization and Excitation" for Li, B, C, N, O, Al, Ga & In.
Version 2.0
July 2003		 Added access to three new, online databases: "Handbook of Basic Atomic Spectroscopic Data" (Z = 1 to 99), "Spectral Data for the Chandra X-ray Observatory" (S, Si, Mg, Ne), & "X-ray Transition Energies" (Z = 10 to 100). Added access to "Radionuclide Half-Life Measurements" for P and Ru. Additionally, there were minor changes made to some of the values of the atomic weights and the ionization energies.
Version 1.2
August 2001		 Activated elements Z = 105-112, 114, and 116; and added access to atomic masses for elements without isotopic abundance. (Access to atomic masses for elements with isotopic abundance was previously available.)
Version 1.1
May 2000		 Minor interface improvements, better page layout.
Version 1.0
September 1999		 Available online.
