Gloriana

The UK Allison & Busby hardcover (1978) is the true first; the US Avon paperback followed in 1979. The 1978 text carries Moorcock's original penultimate/climactic chapter; in 1993 he rewrote that scene, and most later editions carry the revised version (often printed as an appendix), so the Allison & Busby 1978 imprint is the only source of the unrevised original text.
