The Westerbork Northern Sky Survey (WENSS) is a
low-frequency radio survey that will cover the whole sky north
of 
at a wavelength of 92 cm to a limiting flux density
of approximately 18 mJy (
). This survey has a resolution of
and a positional accuracy for strong
sources of 
.
Here we present a source list comprising 11 299 sources and maps of 120
extended sources for a 570 square degree region around the
north ecliptic pole, the so-called mini-survey. We discuss the
errors and reliability of the source parameters and the completeness of
the survey.
