In digital data banks, images travel more frequently from one archive to another than they did in analog archives. Sometimes images that are in the public domain are taken by commercial stock-image agencies and offered for sale. This is the case for a series of images of breaker boys in Pennsylvania that Lewis Hine made in the 1910s as part of his series on child labor. The images are both digitally available for free from the Library of Congress in Washington, D.C., and for a fee from Corbis, Bill Gates’s stock-image company, which offered them for sale until it ceased operations in 2016.
