Duncan, like Dante, was a poet of cosmic imagination, intensely aware of his and poetry's role in the ever-expanding logos of creation. His Selected Poems, first published in 1993, is a "useful and portable compilation," says critic Tom Clark, that "provides the most comprehensive available look at the career of the Bay Area's greatest lyric poet." Editor Robert J. Bertholf has enlarged the original collection to include eleven additional poems and excerpts. The second edition of the Selected Poems fully fleshes out the retrospective of works chosen from the whole of Duncan's writing life. From his early poems through his final Ground Work volumes, as well as his serial poems, "Structures of Rime" and "Passages," composed over the course of thirty years, there emerges a prophetic voice of great perception.
