Every reader knows that a book can change your life.
But what about the lives of an entire generation? Can a book change the future?
Miriam Tuliao, assistant director of central collection development at the New York Public Library, helped us come up with a list of the books that changed the course of history.
We also added a few ideas of our choosing.
From William Shakespeare's plays to George Orwell's "1984," these 30 titles (listed here in alphabetical order) have had a major impact. 
Do you think another book belongs on this list? Let us know in the comments.
