• Vallejo's second poetry collection, Trilce, is a complex and innovative masterpiece consisting of seventy-seven poems rich in inventive syntax and punctuation, as well as intricate imagery. Released in 1922, this work creatively distorts the Spanish language by incorporating Incan expressions and medical jargon to convey deeply personal feelings.

• The book Complete Later Poems: 1923–1938, translated by Valentino Gianuzzi and Michael Smith and published in 2005, compiles all of Vallejo's poetry from his time in Paris until his death. This includes Poemas Humanos, or Human Poems, which is considered one of Vallejo’s finest poetic achievements.

• Vallejo authored Tungsten: A Novel (translated by Robert Mezey and released by Syracuse University Press in 1988) to shed light on the plight of exploited native Peruvians in the tungsten mining sector. The novel, popular in the U.S.S.R. and Spain upon its initial release, complements the themes of "The Black Heralds" and stands as one of the pioneering social-realist novels from Spanish America.

• Ruben Dario’s Selected Writings (2005) offers an English translation of some of the most outstanding poetry by the Nicaraguan modernismo leader, who significantly influenced Vallejo's work.

• "The Black Heralds" mirrors the style of Paul Verlaine’s “Art Poetique,” which was featured in a 1913 anthology that Vallejo studied. It appears again in Selected Poems, a 2000 collection of Verlaine's selected works.

• Pablo Neruda, from Chile, is often regarded as South America's greatest poet. Neruda and Vallejo: Selected Poems (1993) showcases a selection of Neruda’s poetry alongside Vallejo’s, providing a valuable comparison of these two literary giants.
