I've added information about the source of our page images for each edition of Leaves of Grass and added language to the introductory prose that directs users to seek permission to use images from the owners from whom we got them.
Scholars have long relied on print-based resources that are stable, or that remain more or less constant over time. The Whitman Archive, by contrast, changes frequently as new content is added and as errors are located and corrected. This record of additions and changes to the content to the Archive responds to the challenge of creating a digital resource that can serve as a scholarly reference. It represents an effort to be transparent about our methods and history and to render visible changes that would be otherwise largely invisible. We do not record minor changes to the appearance of the site or temporary server outages.
