De revolutionibus orbium coelestium

No book-club era applies. The donor-realistic forms are facsimiles and modern reprints, and these are the tells to check: the numbered, limited facsimile printed in 1943 for the quatercentenary; and the 1972 facsimile from Macmillan / Polish Scientific Publishers / Johnson Reprint Corporation, edited by P. Czartoryski with an introduction by Jerzy Zathey. Modern photographic facsimiles also circulate. Any copy on modern white wove paper, or carrying a modern limitation or colophon leaf, a modern editorial introduction, or a publisher's cloth binding, is a facsimile — not the Petreius sheets. The Great Books of the Western World / Encyclopaedia Britannica set volume is a modern translation, not an edition of the 1543.
