On his retirement in 1953, O'Rahilly acknowledged that some might see CUP as a personal conceit. He said, "no loss has been incurred by any of my publications. I should have had no difficulty in finding other publishers for my books" and, "In 1928 I handed the CUP to the College: since that date the College owns and controls the Press. I have never made nor do I now make, any claims, financial or proprietary, on the CUP." Between 1948 and 1953, O'Rahilly donated £700 and part of his salary to a total of £1,250 to CUP. He took no monetary remuneration from the press.
