  We present the results of a calculation of recombination coefficients for
O^{2+} + e^- using an intermediate coupling treatment that fully accounts for
the dependence of the distribution of population among the ground levels of
O^{2+} on electron density and temperature. The calculation is extended down to
low electron temperatures where dielectronic recombination arising from Rydberg
states converging on the O^{2+} ground levels is an important process. The
data, which consist of emission coefficients for 8889 recombination lines and
recombination coefficients for the ground and metastable states of O^+ are in
Cases A, B and C, and are organised as a function of the electron temperature
and number density, as well as wavelength. An interactive fortran 77 data
server is also provided as an accessory for mining the line emission
coefficients and obtaining Lagrange interpolated values for any choice of the
two variables between the explicitly provided values for any set of
wavelengths. Some illustrations of the application of the new data to nebular
observations are also provided.
