  We present the preliminary results of a survey performed with Swift to
observe a sample of radio-loud Narrow-Line Seyfert 1 Galaxies (RLNLS1s).
Optical-to-X-ray data from Swift are complemented with gamma-ray observations
from Fermi/LAT and radio measurements available in the literature. The
comparison with a sample of bright Fermi blazars indicates that RLNLS1s seem to
be the low-power tail of the distribution.
