  Calculations of the heavy-heavy spectrum present a good opportunity for
precision tests of QCD using lattice techniques. All methods make use of a
non-relativistic expansion of the action and its systematic improvement to
remove lattice artefacts. There was convincing demonstration this year that
these methods work and that the associated perturbation theory is well-behaved.
Comparison to experimental results yields an accurate value for the lattice
spacing, a, a key result in the determination of \alpha_{s}, and (for the first
time this year) the mass of the b quark (4.7(1) GeV).
