Some of it was published in 1906/1907 in the Transactions of the Honourable Society of Cymmrodorion under the title Some incidents in the life of Edward Lhuyd.

He also worked at the Codrington Library at All Souls College, Oxford, and was the only assistant librarian between 1916 and the end of the First World War.

This led to Facsimiles of Letters of Oxford Welshmen (the writers including Henry Vaughan, Sir Leoline Jenkins, Ellis Wynne, Edward Samuel and Moses Williams).

In 1904, he published An Elizabethan Broadside in the Welsh Language, being a Brief granted in 1591 to Sion Salusburi of Gwyddelwern, Merionethshire.
