The Evangelical Library of Wales, an imprint of the Evangelical Movement of Wales, published 18 Lectures on aspects of Welsh Church History between 1971 and 1994, 9 in Welsh and 9 in English. In addition to these, one further lecture was published in 1996 under the “Evangelical Press of Wales” imprint (marked ‘EPW’ below). It is hoped to reproduce these lectures here.
