The volume comprises a collection of 21 songs in Gaelic, with English translations, which were collected by Seán Ó hAnnáin (John Hannon) from the last generation of native Gaelic speakers at the end of the 19th century from the greater Crossmaglen area of Co Armagh.
The original phonetic transcriptions of the songs are available in books I-V of Ó hAnnáin's main manuscript collection (now in the possession of Dr Diarmaid Ó Doibhlin) and from which the contents of this manuscript were copied by his hand also. Ó hAnnáin noted that he supplied copies of the same songs given in this manuscript to other sources, including other contemporary Gaelic collectors, Henry Morris and Seosamh Laoide; the latter's initials (S.L.) are most likely those written on the marginalia of the manuscript by Séamus Ó Casaide.
[The volume had formerly been incorrectly attributed to James Hardiman (1782-1855), historian and lawyer. The compiler was identified as Seán Ó hAnnáin by Dr Gearóid Trimble in 2015, whose assistance is grateful acknowledged.]
