EMSL's Basis set library
From the Molecular Science Research Center's Basis Set Library you
can order Gaussian basis set, and any related effective core
potentials.The basis set can be formatted to several ways for a wide
variety of popular electronic structure packages.

EMSL Computational Results DataBase
This database contains over 30,000
(V1.9 11/11/2000 - 255 Molecules, 41 Atoms (37,071 entries)) pieces of information from
calculations performed with small to very large basis sets, using everything
from simple Hartree-Fock theory to full CI.
The Sicklist database is a listing of problems that arise from
using a particular computational method with a particular molecule.
