The letters, 1900-1925, concern books, publishing, printing and librarianship matters. Many of the letters relate to the publication of J. H. Davies's Bibliography of Welsh Ballads. Some concern the affairs of the Welsh Bibliographical Society or the Carmarthen Antiquarian Society, and some derive from D. Rhys Phillips's work as Welsh Librarian at Swansea.
