The Library of Congress By The People project has released two new datasets from its crowdsourced transcription campaigns, the correspondence of Georgia O’Keeffe and Alfred Stieglitz and the notebooks of Frederick Hockley. The O’Keeffe/Stieglitz dataset includes over 500 letters they wrote between 1929-1947 to their friend Henwar Rodakiewicz, a documentary filmmaker. The digital collection of these letters is also available. The Hockley dataset contains the transcription of his 11 notebooks where he recorded his supernatural visions, which make up volumes 4-5 and 7-15 of The Crystal, his manuscript about his crystal and mirror-gazing experiments.
