  We present a new library of fully-radiative shock models calculated with the
MAPPINGS III shock and photoionization code. The library consists of grids of
models with shock velocities in the range v=100-1000 km/s and magnetic
parameters B/sqrt(n) of 10^-4 - 10 muG cm^(3/2) for five different atomic
abundance sets, and for a pre-shock density of 1.0 cm^(-3). Additionally, Solar
abundance model grids have been calculated for densities of 0.01, 0.1, 10, 100,
and 1000 cm^(-3) with the same range in v and B/sqrt(n). Each model includes
components of both the radiative shock and its photoionized precursor, ionized
by the EUV and soft X-ray radiation generated in the radiative gas. We present
the details of the ionization structure, the column densities, and the
luminosities of the shock and its precursor. Emission line ratio predictions
are separately given for the shock and its precursor as well as for the
composite shock+precursor structure to facilitate comparison with observations
in cases where the shock and its precursor are not resolved. Emission line
ratio grids for shock and shock+precursor are presented on standard line ratio
diagnostic diagrams, and we compare these grids to observations of radio
galaxies and a sample of AGN and star forming galaxies from the Sloan Digital
Sky Survey. This library is available online, along with a suite of tools to
enable the analysis of the shocks and the easy creation of emission line ratio
diagnostic diagrams. These models represent a significant increase in parameter
space coverage over previously available models, and therefore provide a unique
tool in the diagnosis of emission by shocks.
