  We report on a 3600 s spectrum of GRB 021004 obtained with the Nordic Optical
Telecope on La Palma 10.71 hours after the burst. We identify absorption lines
from five systems at redshifts 1.3806, 1.6039, 2.2983, 2.3230, and 2.3292. In
addition we find an emission line which, if due to Ly-alpha from the host
galaxy, gives a redshift of 2.3351. The nearest absorber is blueshifted by 530
km/s with respect to this line, consistent with shifts seen in Damped Ly-alpha
and Lyman-Break galaxies at similar redshifts. The emission line flux is
2.46+-0.50 x 10^-16 erg/s/cm^2. Some of the absorption systems are
"line-locked", an effect often seen in QSO absorption systems believed to
originate close to the QSO central engine.
