    Vellum Manuscript sources
  1. The Book of Hy Many (written 1378-94) ff. 76 a 1-80 c 29.
  2. The Book of Ballymote (written 1384-1406) ff. 268 a 36-281 b 53.
  3. The Book of Lecan (written 1416-18) ff. 194 d 12-202 d 26.
  4. The Book of Lismore (late 15th century) ff. 98 d 20-105 b 21.
  5. National Library Gaelic MS. VI (16th century ?) ff. 13r 1-19v 18 (f.20 is misplaced).
    Paper Manuscript sources
  1. None of the following manuscripts are earlier than the eighteenth century: Royal Irish Academy, Dublin, no. 288 p. 251 (19th century).
  2. Royal Irish Academy, Dublin, no. 485 p. 276 (18th century).
  3. Royal Irish Academy, Dublin, no. 689 p. 103 (18th century).
  4. Royal Irish Academy, Dublin, no. 712 f. 43f (18th century).
  5. Royal Irish Academy, Dublin, no. 756 p. 208 (18th century).
  6. Royal Irish Academy, Dublin, no. 757 (copy of 756) p. 319 (18th century).
  7. Royal Irish Academy, Dublin, no. 930 p. 75a (19th century).
  8. Royal Irish Academy, Dublin, no. 1012 p. 119 (19th century).
  9. Royal Irish Academy, Dublin, no. 1195 p. 1 (18th century). These do not include the two manuscripts of Lismore (nos, 261 by O'Curry and 478 by O'Longan) nor the transcript of Lecan (no. 894 by Connellan). Of these nos. 712 and 1195 are the most important. Nos. 288, 485, 689 and 930 contain only fragments concerning Cashel. These paper manuscripts have not been closely examined. Only no. 712 (23 H 28) had been regularly consulted; it usually agrees with Lismore but is not a mere copy. The Abbotsford Irish manuscript contains a good text of the same recension.
