This is a collection of many works that I'm aware of that are likely in the public domain by the standards of the United States. Don't take the year as gospel, as it's often the year of a publication that I'm aware of, and likely does not reflect the year of writing or original year of publication.
Most of these poems are over a 100 years, and even some of the most progressive writers have works that have not aged well. These poems are not necessarily a representation of my views, but are, if nothing else, an interesting window into some views at the time.
