Oklahomans 2 readers actually get TWO books in one! For perhaps the first time EVER in a printed book, QR Codes (Quick Response Bar Codes) appear throughout the volume aside both narrative passages and sidebar features (biographical sketches, etc.). When you scan these QR Codes with your smart device, they transport you, on the device, directly to the page on this website that contains a larger, unabridged version of that particular passage or feature—more than 200 of them, including more than 100 biographies of great Oklahomans! This provides you with many hundreds of additional pages of Oklahoma History without having to carry around a book that weighs 50 pounds. It’s great for the adult history buff as well as the student working on a report or essay.
