O'Connor published four collections of poetry and was elected to
Aosdána, an elite association of Irish artists, serving as Toscaire (co-leader) in 1990. He worked at the Irish Writers Centre and Irish Writers Union. He contributed to
The Great Book of Ireland and died in 1993. He most admired
Samuel Beckett,
Paul Celan and
Miroslav Holub.
Anthony Cronin described O'Connor as "one of Ireland's most distinctive and experimental poets until his premature death in 1993, dissecting the realities of modern Irish life."
Anne Haverty wrote a poem in his honour in a 1997 issue of
Books Ireland, "Death's Gift." ==Bibliography==
