Manuscripts, [1905x1908]-[1937x1938], of the Rev. David David Williams, comprising mainly essays on cultural, literary and historical topics submitted for competition at the National Eisteddfod; together with a draft summary of a proposed history of Wales, and an album of correspondence and miscellaneous papers.

The records deposited in 1934 included two major groups, the 'Trevecka Group' and the 'Bala College Group'. The former, which represents the largely autonomous 18th-century development of Methodism in Wales, beginning in the 1730s, is centred on the archives of the founding father of Welsh Methodism, Howell Harris, and of the religious community which he established, the 'Trevecka Family'. Besides the 290 volumes of Howell Harris's diaries (for 1735-73), it comprises some 3000 letters, accounts of Societies (individual groups of adherents) and records of Associations. The 'Bala College Group' represents the development of Methodism during the 19th century, its spread in North Wales, the separation from the Established Church in 1811 and the formation of the Confession of Faith in 1823. The accessions of the years 1934 to 1974 include the records of the Sasiwn [the Association], district meetings, colleges, some individual chapels and churches, personal archives (both those of ministers and laymen), and those of the Foreign Mission. In content, the accessions of the years 1974-83 are distinguished from those of the earlier period by the high proportion of records of individual churches, many of them deposited because of the closure of the church. A third series, following a classification similar to that of the second, lists accessions from July 1983 onwards. The records of the North Cardiganshire Presbytery, detailed in a schedule [c.1940], have been withdrawn. Particular mention should be made of the archives of the Foreign Mission, which cover the missionary work of the Church in North East India from its beginning in the 1840s.

The file comprises letters to Hugh Hughes, 1735-1749, all from personal, academic friends, including William Herring, 1740-1749, on literary matters, church officials and preferments, national events in Europe and the West Indies, Denbigh parliamentary election, persecution of Methodists and threat of a French invasion during the Jacobite Rebellion.

A volume containing a holograph translation made in 1810 by the Reverend Ebenezer Richard (1781-1837), Calvinistic Methodist minister, of Tregaron, etc., of an unknown Welsh treatise written in support of the Ordination movement. The title-page reads: 'The Complaint of the Calvinistic Methodists in Wales On account of their being destitute of the Ordinances of Christ in his Churches, viz. Baptism and the Supper of the Lord. Translated from the Ancient British 1810'. According to the dedicatory letter, the translation was undertaken at the request of Ebenezer Richard's friend and patron, Captain James Bowen of Cardigan and subsequently of Llwyn-gwair, Pembrokeshire.
