Although the CUP was not a fully commercial entity, the assessment of manuscripts was rigorous, readers were chosen carefully and were paid an honorarium. The amount was five guineas in 1960, ten guineas in 1967 and forty pounds in 1983. The CUP rejected works of students, amateur authors and memoirists. Some works were rejected due to inadequate resources. Raymond Crotty's "Irish Agricultural Production" (1966) was a notable, quality, landmark publication. The CUP carefully protected its prestige with wariness of co-publications. At times, the CUP committee, experienced difficulties with publishing industry agents, advisers, and printers which could be costly. In the 1980s, CUP established a fruitful relationship with Seán Daly of Tower Books.
