She's Come Undone

The Pocket Books (New York) hardcover of August 1992 is the true first, and the census attribution is correct; Pocket Books is a Simon & Schuster imprint, which is why some records credit Simon & Schuster as publisher for the same book. No UK or foreign edition precedes it — Lamb is American and this was a US debut. The trap here is format rather than country: the title is overwhelmingly encountered as a trade paperback, and only the 1992 Pocket hardcover is the first edition. One general-reference summary describes the novel as appearing in hardcover and paperback, but the points references consulted treat the August 1992 hardcover as the first, and no evidence of a simultaneous or preceding paperback issue was found. Any paperback, including the earliest Pocket trade paperback, is a later issue.
