  The status of lattice calculations of the quark spin, the quark orbital
angular momentum, the glue angular momentum and glue spin in the nucleon is
summarized. The quark spin calculation is recently carried out from the
anomalous Ward identity with chiral fermions and is found to be small mainly
due to the large negative anomaly term which is believed to be the source of
the `proton spin crisis'. We also present the first calculation of the glue
spin at finite nucleon momenta.
