Mark Eisner conceived, edited, and was one of the principal translators for The Essential Neruda: Selected Poems (City Lights, 2004). For Neruda's centennial that year, Eisner was interviewed on NPR's Morning Edition. Eisner has also written what the bestselling novelist Cristina García called a "definitive" biography on Neruda, Neruda: The Poet's Calling, one that "reads like a beautifully written novel," forthcoming from Ecco in March 2018. Finally, he is currently producing a documentary on Neruda, to be completed in 2018, with support from Latino Public Broadcasting. An initial, short version of the documentary, narrated by Isabel Allende, won the Latin American Studies Association Award of Merit.
Other work includes his critically acclaimed translation of the Spanish poet and scholar Tina Escaja's award-winning book-length poem Free Fall / Caída Libre (Fomite Press, 2015.) He was also involved with the founding of the literary non-profit Red Poppy Art House in San Francisco. He and Escaja also co-edited a forthcoming multilingual anthology of Latin American Poetry in Resistance, a project of Red Poppy, dedicated to promoting the power of Latin American poetry to evoke social consciousness.
