Mr. English is the author of, among other books, “The CIA Book Club: The Secret Mission to Win the Cold War with Forbidden Literature.”

I traced a copy of George Orwell’s “1984” to the library of the social sciences department at Warsaw University, a literary treasure trove heavy with the scent of dust and old paper, and so jammed with shelves that in places the only way to move around was sideways. For months I had been searching for this particular volume, a book that had played, in my view, a small but significant role in winning the Cold War.
