For books older than it of course, from books that were influential in a literary sense like Iliad and Odyssey or Shakespeare or Lord of The Rings to those that had an impact on the society like Plato's Republic or Marx's works or The Prince,(Or the five religious books of the most influential religions for the epitome of social influence) to the scientifically influential books to a tons of other examples, but for the newer books I can't think of anything and I think the current volume of available books and how easy it's to access them and find your own niche although a very welcome change makes it hard for a single book or series to stand out as much.
