These are out of print or historical editions, which we clean, straighten, touch up, and digitally reprint. Due to the age of original documents, you may find occasional blemishes, damage, or skewing of print. While we do extensive cleaning and editing to improve the image quality, some items are not able to be repaired. A portion of each book sold is donated to small performing arts organizations to create jobs for performers and to encourage audience growth.
