Should any writer down the road choose to give William Butler Yeats the treatment Colm Tibn has given Henry James, Scribner's 14-volume series on the writings of Yeats will surely be invaluable. The latest volume, titled "W.B. Yeats Early Articles and Reviews," edited by John P. Frayne and Madeleine Marchaterre, explores articles and reviews written between 1886 and 1900. Obviously this is not exactly light reading. Still, fans of Yeats will likely be fascinated by the extent to which Yeats was deeply engaged in intellectual arguments of his time, particularly those revolving around the "Irish Renaissance" he famously championed. Already collected by Scribner have been the poems, plays and early and later essays of Yeats. Up next are later articles and reviews, "mythologies," and two volumes intriguingly entitled A Vision.
