Where can I find tables of ionization energies on the Web?

Data For General, Organic, and Physical Chemistry (Franklin and Marshall College)
Data tables for general, organic, and physical chemistry, including electronegativies, enthalpies of formation, ionization energies, electron affinities, bond energies and bond lengths, lattice energies, entropies, atomic and ionic radii, solubilities, dissociation constants, vapor pressures, electrode potentials, and character tables.

NIST Atomic Spectroscopic Database (National Institute of Standards and Technology)
Energy levels, transition probabilities, and wavelengths for atomic line spectra. Ionization energies for neutral atoms are also available on a hyperlinked periodic table.

NIST Chemistry WebBook (National Institute of Standards and Technology)
Property and spectral data for elements, organic compounds, and small inorganic compounds can be retrieved by chemical formula, name, partial formula, CAS registry number, molecular weight, or by thermochemical properties. The database includes thermochemical data (enthalpies, entropies, heat capacities, ...) for several phases and for reactions and phase transitions, ion energetics data (ionization energies, electron affinities, ...) and spectroscopic information (IR, UV, visible, and mass spectra).

WebElements Periodic Table (Mark Winter, Sheffield University)
The quintessential element database. Each element entry is accessed from a clickable periodic table, and contains a staggering amount of information, including atomic properties (ionization energies, electron affinities, effective nuclear charges, valence shell radii, isotopes, ...), bulk properties, VR crystal structures, thermal properties, lists of compounds, bond enthalpies, reduction potentials, and some context (industrial uses, geological occurrence, and biological role).
