Low frequency radio waves, while challenging to observe, are a rich source of information about pulsars. The LOw Frequency
ARray (LOFAR) is a new radio interferometer operating in the lowest 4 octaves of the ionospheric "radio window": 10-240 MHz,
that will greatly facilitate observing pulsars at low radio frequencies. Through the huge collecting area, long baselines,
and flexible digital hardware, it is expected that LOFAR will revolutionize radio astronomy at the lowest frequencies visible
from Earth. LOFAR is a next-generation radio telescope and a pathfinder to the Square Kilometre Array (SKA), in that it incorporates
advanced multi-beaming techniques between thousands of individual elements. We discuss the motivation for low-frequency pulsar
observations in general and the potential of LOFAR in addressing these science goals. We present LOFAR as it is designed to
perform high-time-resolution observations of pulsars and other fast transients, and outline the various relevant observing
modes and data reduction pipelines that are already or will soon be implemented to facilitate these observations. A number
of results obtained from commissioning observations are presented to demonstrate the exciting potential of the telescope.
This paper outlines the case for low frequency pulsar observations and is also intended to serve as a reference for upcoming
pulsar/fast transient science papers with LOFAR.
