He has collaborated on limited editions with poet Denise Duhamel (for the DVD animation “Laiterie”) and artist Trevor Winkfield (for the silkscreen portfolio "I Come In Search Of Walnuts").
More recent experiments of collaborative poetry include the collaborative works of American poets Denise Duhamel and Maureen Seaton, who have been writing poetry together for 15 years and have published three collaborative books: Exquisite Politics (1997), Oyl (2000) and Little Novels (2002).
Her best selling and most popular book to date, Kinky (1997), marries her bent for satire, humor, and feminism in portraying an icon of popular culture, the Barbie doll, through an extended series of satirical postures ("Beatnik Barbie," "Buddhist Barbie," etc.).
Her newest book, Nothing Between Us: The Berkeley Years, a novel in prose poems set in Berkeley in the sixties (Del Sol Press, 2009), has been called “unforgettably moving” by Sandra M. Gilbert; “a captivating page-turner” by Alicia Ostriker; and an “exciting tribute to a decade of change” by Denise Duhamel.

The poet David Graham has described Halliday as one of the "ablest practitioners" of the "ultra-talk poem," a term said to have been coined by Halliday himself to describe the work of a group of contemporary American poets, including David Kirby, Denise Duhamel, David Clewell, Albert Goldbarth, and Barbara Hamby, who frequently write in a wry, exuberant, garrulous, accessible style.
In 2004, Pfefferle published Poets on Place, the story of his year-long trip around America interviewing and photographing American poets: Mark Strand, Rita Dove, Denise Duhamel, Charles Wright, Mark Wunderlich, Henry Taylor, David St. John, and Nikki Giovanni.
