The Story of the Glittering Plain (1891) was the first publication issued by the Kelmscott Press. The Golden Legend (1892), a much larger book, was slated to hold this distinction, but the paper initially supplied by J. Batchelor and Son would have only allowed for two pages to be printed at a time. The Story of the Glittering Plain is the only title which was published twice by the Kelmscott Press, the second edition (1894) being set in Troy and Chaucer types and bearing 23 wood-engravings by Walter Crane.
