Editing César Vallejo (section)

===Essay===
Vallejo published a chronicles book entitled ''Russia in 1931. Reflections at the foot of the Kremlin'' (Madrid, 1931) and prepared another similar book for the presses titled ''Russia before the second five-year plan'' (finished in 1932 but was later published in 1965).

Also, he organized two prose books about essay and reflection: ''Against Professional Secrecy'' (written, according to Georgette, between 1923 and 1929), and ''Art and Revolution'' (written between 1929 and 1931), which bring together diverse articles, some which were published in magazines and newspapers during the lifetime of the author. No Spanish editorial wanted to publish these books because of their Marxist and revolutionary character. They would later be published in 1973.
