A computus manuscript, now lost, which appears to have been consulted by Bede in the library of Jarrow and which is thought to have been an influential resource when he wrote his own computistical treatise De temporum ratione. To an extent, its contents can be reconstructed from an 11th-century copy in the so-called Sirmond manuscript and other, related manuscripts, although the precise extent of the material that can be said to derive from the lost compilation is uncertain. Charles W. Jones originally singled out a narrower set of items (items 13-45 in his catalogue description of the Sirmond manuscript), but on later occasions, revised his opinion.

A manuscript now lost but cited by name in Keating’s Foras feasa Érinn (iii 32) and Dubhaltach Mac Fhir Bhisigh’s Leabhar mór na ngenealach.
Irish manuscript now lost but cited by Mícheál Ó Cléirigh as a source for his transcription of the text Cogad Gáedel re Gallaib, of which he made a secondary copy in Brussels MS 2569-72 (dated March 1628 from Multyfarnham, Co. Westmeath). The title suggests an association with the bardic poet Cú Chonnacht Ó Dálaigh (d. 1139).
A manuscript now lost but cited as a source in Irish genealogical material.
Manuscript used as an exemplar for texts in the Dublin, Royal Irish Academy, MS 23 P 12.
A manuscript now lost but apparently credited as a source for three poems in Brussels, Bibliothèque Royale de Belgique, MS 5100-5104, p. 53, in which Suibne is said to have composed the verse: Tuiccther asin rand sin ⁊ as an dá dhán gurab é Suibhne dorinne iad gé gurab ar Moling chuires as sein-leabhar iad .i. leabhur Murchaid meic Briain, “It is understood from this poem (rann) and from the two poems (dán) that Suibne composed them, although the old book, i.e. the book of Murchad mac Briain, attributes them to Moling”). The manuscript is apparently named for Murchad mac Bríain, i.e. son of Brían Bóruma.
A manuscript now lost but cited as a source for a genealogical tract on the Dál Fiatach.
Irish and Latin variants of the title ‘the Book of Sligo’ are attested in a number of sources from the 15th and 17th centuries. Its identity cannot be established beyond doubt nor is it necessarily true that the references are all to the same manuscript. Pádraig Ó Riain (CGSH, p. lii) has shown that those at least that can be dated to the 17th century refer to the Book of Lecan (Co. Sligo): these are James Ussher’s quotation of a triad about ‘St Patrick’s three Wednesdays’ and a Latin note added (by Ussher?) to a copy of the Vita sancti Declani which credits the Liber Sligunt as the source for a copy of the genealogies of Irish saints. There are two 15th-century mentions by the Irish title Leabhar Sligigh: one by the scribe of Aided Díarmata meic Cerbaill (first recension) in Egerton 1782, who acknowledges the Leabhar Sligig as having been the exemplar of his text; and an honourable co-mention, with Saltair Caisil, in a poem on the king of Tír Conaill, beg. Dimghach do Chonall Clann Dálaigh. Aided Díarmata is not found in the Book of Lecan, at least in the form in which it survives today. Ó Riain allows for the possibility that ‘the Book of Sligo’ “is indeed a lost codex whose name was mistakenly applied in the seventeenth century, perhaps by Ussher, to the well-known Book of Lecan”.
A manuscript now lost but used by Mícheál Ó Cléirigh as an exemplar for the Life of Mo Ling in Brussels, Bibliothèque Royale de Belgique, MS 4190-4200, f. 53v: I nAthcliath do scriobad as Leabhur Tighe Molling. Ocus léiccim Moling atá il-Laidin i muinigin na mbrathar Ccléirigh cidh im Cléirich-sa féin .15. juil. 1628 (‘In Dublin (this) has been copied out of the Book of Timulling. And I leave Moling's miracles, which are in Latin, in trust of the friars Clery, though I myself am a Clery, 15 July, 1628’ - ed. and tr. by Stokes).
