  Narrow-Line Seyfert 1 galaxies have been established as a new class of
gamma-ray emitting AGN with relatively low black hole masses, but
near-Eddington accretion rates. Other extragalactic gamma-ray sources observed
so far such as Flat Spectrum Radio Quasars, Radio Galaxies, and BL Lacertae
Objects generally exhibit much higher black hole masses and, in the case of BL
Lac objects and FRI Radio Galaxies, much lower accretions rates. The
multifrequency campaign of 2013 centered on the bright source 1H 0323+342 will
provide further insights into the nature of the jets and their gamma ray
production mechanisms in a largely unexplored corner of AGN parameter space.
Here, we show preliminary results of this campaign and discuss them.
