Looking forward to reading this selection! I went with Hamlet53's recommendation of
The Best of Frank O'Connor from the Amazon Kindle Store. Thank you! It was edited by Julian Barnes with input from his widow, Harriet O'Donovan Sheehy. I like the way it's organized into categories such as war, childhood, writers, Ireland, abroad, "last things" and several more. It also has a chronology and explanation of Irish historical events at the beginning which appeals to my research tendencies.
