High Quality Content by WIKIPEDIA articles! Serio Oriento-Okcidento (East-West Series in Esperanto) is a publication series initiated by the World Esperanto Association, which aims to contribute to the "Program of UNESCO for the Study and mutual appreciation of cultures ". In the series, particularly important and representative works of world literature are translated into Esperanto. Various publishers have gradually contributed to the Serio, who have published books according to their ability and financial responsibility. The Steering Committee ("Estraro") of the UEA approves the work for the Serio according to publisher`s proposals, but the UEA has no financial responsibility.
