  We present high-precision VI photometry of stars from the middle of the giant
branch to about 5 magnitudes below the main-sequence turnoff in the globular
cluster Palomar 13 based on images obtained with the Keck II 10m telescope. We
tabulate a complete sample of blue stragglers in the cluster out to about 18
core radii. The blue straggler population is significantly more centrally
concentrated than the giant star sample, which is in turn significantly more
centrally concentrated than the main-sequence star sample. Palomar 13 has one
of the highest specific frequencies of blue stragglers of any known globular
cluster, but the specific frequency of blue stragglers in the outskirts of the
cluster does not increase as has been seen in denser clusters. We also identify
a group of faint blue stragglers (bluer than the turnoff, but having about the
same magnitude) that outnumbers the brighter stragglers by more than a factor
of 2. The cluster's color-magnitude diagram shows a large excess of stars to
the red of the main sequence, indicating that the cluster's binary fraction is
at least 30% +/- 4%, which appears to be similar to that of the low-mass
cluster E3 but significantly higher than that of the more massive clusters Pal
5 and NGC 288.
