Encyclopedia of Esperanto

Encyclopedias in Esperanto (Esperanto: Enciklopedio de Esperanto) There have been several different attempts of creating an encyclopedia of all Esperanto topics. A modern Esperantist encyclopedias include the () or the Enciklopedio Kalblanda.

In 1913 Petro Stojan proposed a Universal Monograph Encyclopedia (Esperanto: Universala Slipa Enciklopedio), which would be continuously published with separate monographs for each subject. The first five monographs ("The Encyclopedia and its future", "Kinematic theory on time", the hymn "La Espero", "Transcription of proper names", and "Gathering", a poem by L. Levenzon) were published at that time.

In 1917, in Petrograd, Vladimír Szmurlo published another encyclopedia called Ariadne's Thread, with mere references as "A first try of an Encyclopedia of Esperantism; with a firm belief that out of that ... seed will grow a huge tree of the Universal Esperanto Encyclopedia." The first pages (1–88) were printed in Riga. Due to military circumstances, the next pages of the book appeared infrequently, only after the letter "E", and with contents in very short supply and content.
