I have made three corrections to transcriptions in the Published Works section of the site:1. In the 1881-1882 edition (http://whitman-dev.unl.edu/published/LG/1881/whole.html), I corrected the capitalization of ñ to Ñ, where necessary.
2. In the 1856 edition (http://whitmanarchive.org/published/LG/1856/whole.html), I corrected the mis-transcription "enemies'lands" to "enemies' lands"
3. In "A Death Sonnet for Custer" in the Poems in Periodicals section, http://www.whitmanarchive.org/published/periodical/poems/per.00142, I corrected the singular "Cañon" to "Cañons" in the editorial footnote to the poem.
Brett Barney pointed out these errors.
