The Muckross Newsletter, a successor to ROS, has been published since 1996, on behalf of the Trustees of Muckross House, by Muckross House Research Library. Originally two issues of the newsletter were produced every year. However, in more recent times, one single, enlarged, issue has been produced annually, usually around Christmas. The Muckross Newsletter contains a mixture of news and events relating to Muckross, together with a number of articles covering our most recent areas of research. It is compiled and edited by Patricia O’Hare, Research and Education Officer. All queries concerning the Muckross Newsletter should be addressed to firstname.lastname@example.org A limited number of past issues of the Muckross Newsletter are still available upon request.
