The catalogue presented here offers a survey of all the available literature on the distribution of Irish spiders. The species names have been up-dated to take account of recent taxonomic and nomenclatural work but it has not been possible to check the validity of the records themselves, because the original material has not been re-examined. It is hoped that this catalogue will enable future students of the Irish spider fauna to find and use the sources of data on distribution and ecology and that it will thus support progress in Irish spider faunistics.
