This book is a resource to enable scholars and students in Yeats studies to explore the materials in his library, which, together with his unpublished papers and manuscripts, forms part of the writer's archive in the National Library. Continuing from the first volume (Reading Notes), Volume II describes copies of books he wrote or edited solely in his name and subsequently revised or marked for other purposes, on occasion aided by his wife and others.This book could not have been written without the generous participation of the Yeats family over many years. Their legacy, now entrusted to the National Library, is robust and endless in potential. This book is about individual cases but also the building of an oeuvre.
