When Emily Dickinson encountered her first real book as a child, she experienced a moment of pure, joyful recognition. “This, then, is a book!” she exclaimed. “And there are more of them!” The Atlantic would go on to publish Dickinson’s poems; perhaps more important, it introduced her to a lifelong mentor, Thomas Wentworth Higginson. After Dickinson read his article “Letter to a Young Contributor” in the April 1862 issue of The Atlantic, she wrote to him, beginning a decades-long correspondence. Higginson would, eventually, help put together the first collection of her poetry. Looking back, I’m grateful for that early, elated meeting of reader and reading material. This, then, is a book!
