I have enclosed a link to a website that publishes books on Irish genealogy by county.
Over the years I have found several of them extremely useful in my research and highly recommend them to researchers no matter what level you are researching from.
There are 15 titles available at the moment. I'm sure if you have any questions on how to obtain a copy of any one title I am sure they will be delighted to hear from you.
