In '1984', what is the title of the forbidden book by Emmanuel Goldstein?

In George Orwell’s “1984,” the forbidden book by Emmanuel Goldstein is “The Theory and Practice of Oligarchical Collectivism.”

Winston Smith first hears of it as a terrifying underground book, supposedly written by Goldstein, the Party’s declared enemy. O’Brien later gives Winston a copy, allowing him to read its analysis of Oceania’s political system and the Party’s methods of control.

The book explains ideas such as perpetual war, social hierarchy, manipulated history, and the Party’s pursuit of power for its own sake. It is often called simply “the book” in the novel, which can cause confusion, but the title appears on its title page.

Orwell’s fictional work echoes real political writing, especially Leon Trotsky’s critique of Stalinism, The Revolution Betrayed, and James Burnham’s The Managerial Revolution. Another twist is that O’Brien claims the book was produced collectively by members of the Inner Party, making Goldstein’s authorship—and possibly the Brotherhood itself—part of the regime’s deception.
