If This Is a Man (US: Survival in Auschwitz; Se questo è un uomo)

No book-club issue is documented for the 1947 De Silva in the sources consulted. The 1961 Collier Books paperback is a mass-market retitling of the same Woolf translation, not a new text, and is a reprint. Later Einaudi issues — Saggi, Super ET, ET Scrittori, the school editions and the omnibus pairing with La tregua — are all reprints or "first thus" repackagings of the 1958 revised text and carry modern ISBNs. The single most common misattribution is treating any Einaudi copy, including 1958, as the first edition; only the 1947 De Silva Biblioteca Leone Ginzburg volume is.
