On the Origin of Species by Means of Natural Selection

Numerous later facsimiles and photo-reprints exist (e.g., the Harvard facsimile edition) and carry later imprints or explicit facsimile statements. A genuine 1859 first is identified by the 1859 title-page date together with the two-quotation half-title verso; the 'speceies' misprint and the June 1859 Murray ads are corroborating, not decisive, and neither the ads' presence nor the misprint alone proves a first.
