Hilbert's own Nemean Lion Press issued a hand-sewn, signed-limited edition of "Fletching of Hackles", a collaborative effort by Hilbert and David Yezzi. The book, designed by Jennifer Mercer and bound by Melissa Moffa, consists of dueling limericks and clerihews in which Hilbert and Yezzi challenge and insult each other. It is limited to 24 numbered copies with four authors' and artists' proofs, all signed by Hilbert, Yezzi, Mercer, and Moffa. The second title from the press was "3 X 5" ["Three by David Yezzi, Five by Ernest Hilbert"] a small tête-bêche folio, hand-sewn issued in 2010, in Prussian-blue faux-snakeskin binding with cutaway title windows, stiff eggshell-blue wrappers, limited to 12 copies signed by designer, bookmaker, and both authors, only eight for sale by subscription. The third title from the press was "Two Ranges ", a hand-sewn concertina book that unfolds vertically to display two poems about mountaineering, one each by Hilbert and Yezzi on opposite sides, limited to sixteen total copies signed by both authors, only twelve for sale (two authors’ and two artists’ proofs, hors série). It was the final book issued by the press.
