The Welsh-language Primary Sector and Secondary Sector awards honour one book written for primary school children and one for secondary school children. It is sponsored by the British Chartered Institute of Library and Information Professionals, Cymru Wales division (CILIP/Wales), and presented at that association's annual conference in May. The English-language award honours one book with an "authentic Welsh background" whose original language is English. The awards are named for Tír na nÓg, the "Land of the Young", an otherworldly realm in Irish mythology. Their purpose is " the standard of children's and young people's books and to encourage the buying and reading of good books." There is no restriction to fiction or prose. They are presented by the Books Council of Wales to the best books published during the preceding calendar year in each of three awards categories, one English-language and two Welsh-language. The Tir na n-Og Awards (abbreviated TnaO) are a set of annual children's literary awards in Wales from 1976.
