  We present initial pulsar results from the first station of the Long
Wavelength Array (LWA1) obtained during the commissioning period of LWA1 and
early science results. We present detections of periodic emission from 44
previously known pulsars, including 3 millisecond pulsars (MSPs). The effects
of the interstellar medium on pulsar emission are significantly enhanced at the
low frequencies of the LWA1 band (10--88 MHz), making LWA1 a very sensitive
instrument for characterizing changes in dispersion measures (DM) and other
effects from the interstellar medium. Pulsars also often have significant
evolution in their pulse profile at low frequency and a break in their spectral
index. We report DM measurements for 44 pulsars, mean flux density measurements
for 36 pulsars, and multi-frequency component spacing and widths for 15 pulsars
with more than one profile component. For 27 pulsars, we report spectral index
measurements within our frequency range. We also introduce the LWA1 Pulsar Data
Archive, which stores reduced data products from LWA1 pulsar observations.
Reduced data products for the observations presented here can be found on the
archive. Reduced data products from future LWA1 pulsar observations will also
be made available through the archive.
