Is éard atá i gCnuasach Bhéaloideas Éireann cartlanna Lámhscríbhinní, Grianghrafadóireachta agus Fuaime/ Físe, Sainleabharlann agus Cartlann Ceoil. Tá thart ar 3 milliún leathanach lámhscríbhinne sa Chnuasach, chomh maith le hinnéacs cárta 300,000 mír agus innéacsanna ríomhairithe eile, na mílte uaireanta taifeadtaí fuaime (lena n-áirítear fiteáin chéarach luatha), thart ar 70,000 grianghraf agus léaráid agus cnuasach péintéireachtaí. Tá faisnéis maidir le gnéithe de bhealóideas agus saol tuaithe gach contae in Éirinn mar chuid den Chnuasach, chomh maith le roinnt ábhair a bailíodh in Albain, Manainn, sa Bhriotáin agus i Stáit Aontaithe Mheiriceá. Tá 50,000 éigin leabhar clóite, tréimhseachán agus seach-chló sa sainleabharlann a bhaineann le béaloideas na hÉireann agus leis an mbéaloideas comparáideach, le heitneolaíocht agus le réimsí bainteacha. Cuimsíonn acmhainní do Chnuasach Bhéaloideas Éireann acmhainní airgeadais agus daonna, chomh maith le háitreabh. Rinne COBÁC leithdháileadh buiséadaithe ar leithligh sa bhliain 2006 ar mhaithe leis an gCnuasach a chothabháil. Léirítear sna poist foirne scaradh ábhar acadúil Bhéaloideas na hÉireann ó Chnuasach Bhéaloideas Éireann, a rinneadh ag an uair chéanna a bunaíodh an Cnuasach mar aonán ar leithligh. The National Folklore Collection consists of Manuscript, Photographic and Audio/Video Archives, a specialist Library, and a Music Archive. The Collection contains approximately 3 million manuscript pages, a 300,000-item card index and other computerised indices, thousands of hours of audio recordings (including early wax cylinders), approximately 70,000 photographs and drawings, and a collection of paintings. Information regarding aspects of the folklore and folk life of every county in Ireland is contained in the Collection, as well as some material collected in Scotland, the Isle of Man, Brittany and the USA. The specialist library contains some 50,000 printed books, periodicals and offprints relating to Irish and comparative folklore, ethnology and related fields. Resources for the National Folklore Collection comprise financial and human resources as well as premises. In 2006 a separate budgetary allocation was made by UCD for maintenance of the Collection. The separation of the academic subject Irish Folklore from the National Folklore Collection, which coincided with the establishment of the Collection as a separate entity, is reflected in staff positions.
