  The FIRST (Faint Images of the Radio Sky at Twenty Centimeters) survey now
covers 1550 square degrees of sky where $07^{h}16 < \alpha < 17^{h}40$ and
$28^{\circ}.3 < \delta < 42^{\circ}$. This yields a catalog of 138,665 sources
above the survey threshold of 1 mJy, about one third of which are in
double-lobed and multi-component sources. We have used these data to obtain the
first high-significance measurement of the two-point angular correlation for a
deep radio sample. We find that the correlation function between $0.02^{\circ}$
and $2^{\circ}$ is well fitted by a power law of the form $A\theta^{\gamma}$
where $A\approx 3\times 10^{-3}$ and $\gamma\approx -1.1$. On small scales
($\theta<0.2^{\circ}$), double and multi-component sources are shown to have a
larger clustering amplitude than that of the whole sample. Sources with flux
densities below 2 mJy are found to have a shallower slope than that obtained
for the whole sample, consistent with there being a significant contribution
from starbursting galaxies at these faint fluxes. The cross-correlation of
radio sources and Abell clusters is determined. A preliminary approach to
inferring spatial information is outlined.
