Hilbert's second collection, "All of You on the Good Earth", was published on March 1, 2013. According to the publisher, it "guides the reader through chambers occupied by visionary gravediggers, spaced-out movie stars, frenzied dropouts, sullen pirates, and unrelenting stalkers, noble war correspondents and cornered dictators, unlucky drunks and supercilious scientists, impatient goddesses and sad sea monsters, zoned-out denizens of Plutonian strip-clubs and earnest haunters of ancient ruins, the infamous Rakewell in TriBeCa and sea nymph Kalypso in a beach house at the Jersey shore, characters wandering an America demoralized by economic decline. These poems contain fasts and feasts, laments and love songs, histories, fantasies, and elegies, the amusing and heartbreaking debris of life on this world, all the while recalling Seneca’s dictum, non est ad astra mollis e terris via ('the road from the earth to the stars is not easy')." His third collection, "Caligulan", was published on September 24, 2015 by Measure Press. It is described by the publisher as "a book haunted by the poet’s many affections and angers, its poems animated by horror films and science-fiction novels, heavy metal and opera, remote wilderness and ruined cities. Departing from the experimental sonnet forms he pioneered in his earlier books, Hilbert delivers a chorus of poems that are conversational yet bizarre, stormy and surreal yet dexterously accomplished; brash, abrupt, and sometimes scathingly sarcastic. In four chapters of fourteen poems each, Hilbert leads the reader through modern America’s triumphs and tragedies, elusive consolations and primeval horrors, all the while telling jokes, posing questions, and sounding warnings of things to come."
