About the Publisher In the 1930s, Manuel H. Barron opened a bookstore in Brooklyn, New York. People from the community asked Mr. Barron about books that might be available to help their children study for the New York State Regents exams. After realizing there wasn't anything available, Mr. Barron's created his own study guides. 80 years later, Barron's has helped millions of people prepare for their next step.
