RR Lyrae stars are of great importance for investigations
of Galactic structure.
However, a complete compendium of all RR-Lyraes in the solar neighbourhood
with accurate classifications and coordinates does not exist to this day.
Here we present a catalogue of 561 local RR-Lyrae stars
(
mag) according to the magnitudes given
in the Combined General Catalogue of
Variable Stars (GCVS)
and 16 fainter ones.
The Tycho2 catalogue
contains 
100 RR Lyr stars.
However, many objects have
inaccurate coordinates in the GCVS,
the primary source of variable star information,
so that a reliable cross-identification is difficult.
We identified RR Lyrae from both catalogues based on
an intensive literature search.
In dubious cases we carried out photometry of fields to identify the variable.
Mennessier & Colome (2002, A&A, 390, 173) have published a paper with
Tyc2-GCVS identifications,
but we found that many of their identifications are wrong.
