A more extensive collection would be the volumes of: "Duanaire Dháibhidh Uí Bhruadair I - III" (McErlean, J.C., ed.). Cumann na Scríbheann nGaedhilge/Irish Texts Society (ITS), 1910 - 1917.
If and when I ever have a day to spend at the library of the University of Ulster, Coleraine, I might be able to look through these books. (I'd start with the smaller one recomended by Mían). But I don't know why I THINK Ó Bruadair is the authot of the original Tomás an Buile. And James Stephen's "Collected Poems" are also held at UU, Coleraine.
