ISTC: Also recorded as [Johann Gutenberg?], 1460 and [between 1460 and about 1472]. Three issues can be distinguished in spite of identical typesetting: a) printed on vellum or Bull's Head paper; b) on Galliziani paper; c) on Tower & Crown paper. This has given rise to the theory that issue a) was printed in 1460, issue b) in 1469 and issue c) about 1472; see P. Needham, in BSA 76 (1982) pp.395-456 and the articles "zur Catholicon-Forschung" in Wolfenbütteler Notizen zur Buchgeschichte 13 (1988) pp.105-232. For an alternative theory that all three states were printed about 1469, see L. Hellinga in Gb Jb 1989 pp. 47-96 and in the Book Collector (Spring 1992) pp. 28-54.
