His recent critical studies, "x, y, z, t: Dimensions of Science Fiction" (2004), "Ferocious Minds: Polymathy and the New Enlightenment" (2005) and "Unleashing the Strange" (2009) were released by a small US press, Wildside. Several of his books feature cover art by Swedish transhumanist Anders Sandberg, including "Earth is but a Star" (2001), Broderick's anthology of science fiction stories, and thematically related critical discussions, concerned with the far future. In 2012, with Paul Di Filippo, he published "Science Fiction: The 101 Best Novels, 1985–2010," which was short-listed for a 2013 Locus Award.
