Recently, research material originally produced during the mid-to-late 19th century and early 20th century by researchers at the Harvard College Observatory was re-discovered in the HCO Plate Stacks holdings. These early notebooks and other materials are absolutely irreplaceable and they represents the history of the Harvard College Observatory. The Wolbach Library has embarked on a journey to help preserve Harvard early data and research in astronomy.
