Publishing mattered to Shelley. But he knew that he was not a successful author certainly by comparison with Byron with whom he was regularly in proximity, especially in Italy. As a schoolboy and university student, Shelley arranged for the printing, advertising, and distribution of his verse and prose with boldness and ambition, sometimes putting those who printed, published, and sold it at risk on legal grounds. A significant proportion of what he published or intended to publish as a mature writer was also withdrawn or suppressed or did not appear because it was not publishable at the time. The gradual emergence of a significant amount of his writing hitherto unpublished, or not published in full, in editions curated by his widow from 1824 until her death established his reputation. However, it has taken until the early twenty-first century for his manuscript and print oeuvre to come into fuller view.
