We have updated the editions of Leaves of Grass to standardize the presentation of the Tables of Contents and horizontal bars. I have also added two commas that were missing in the copyright statement associated with the 1891-2 edition.
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.
