Books as a whole have been banned in Ray Bradbury's dystopian sci-fi masterpiece Fahrenheit 451. This blanket ban on all of literature is key to the plot of the novel. Even the title refers back to it: Fahrenheit 451 is the temperature at which paper burns.
That said, specific books are referenced and alluded to throughout the novel. As all books have been banned, any book that is referenced is a banned book, so any of them would work as an example with which to answer your question.
To emphasize just how much culture is lost when books are banned, Bradbury makes a point to reference a great many classics and cultural staples. For example, during Montag and Captain Beatty's discussion in part 1 about how books came to be banned, William Shakespeare's Hamlet comes up and Beatty explicitly states: "you know the title certainly, Montag; it is probably only a faint rumour of a title to you, Mrs. Montag."
At the end of the novel, when Montag meets up with a group of rebellious, runaway intellectuals, a great number of books that Montag will now have access to are referenced in quick succession, among them: Plato's Republic, Gulliver's Travels, Walden, and the Bible.
